Is there any possibility of turning on the system and checking if it boots? Which Operating System was being used before it was turned off? How long ago was the system run? Where has it been stored? Do you have any terminals? Should he bring one with him? Would a VT100 be satisfactory? Jerome Fine Hi Jerome The system was running RSX11M+, and it was used as an RMCS. It had about 6 terminals on it and was gathering data from about 10 sites. I was shut down in 2000 and I have had it since then. It has been in my garage the whole time. There have been no rodents or anything. I used the RMCS but didn't do any of the work on the system. As far as I know the cables were unplugged and put into each cabinet. One of the MDI disks was taken from cabinet 3 by someone I don't know whether it was a MDI 76 or 276. I don't have any terminals That I would be sure works as I never tried to get it going again. It also had two RK07 attached to it that I couldn't get. I do have some spare cards and the original cpu cards that would go with it. It would be a bit of a project to start it up I guess, I don't know which disk it boots off, hopefully not the that's missing.

The service guide mentions a "two level" environment with a "basic" level and a "customer program" level. I'm hoping it means there is a Basic interpreter but I'm not convinced. The manual also mentions a "D12 assembler" as the develoment environment.

Thinking about it, I seem to remember seeing some picture of an 11/70 with bulbs as well, but all 11/70 machines I've seen or worked on had LEDs, so I suspect they might have had bulbs initially as well.

DEC used little modules containing an LED and series resistor that were the same size as the bi-pin T1+3/4 bulbs used earlier. In a CPU panel you had to clip out the pre-heat resistors, for obvious reasons. My 8/e is like that, although I think some 8/e's had bulbs. I've seen RK05s with bulbs and RK05s with LED modules. My 11/45 (I forget the serial number, it's early, perhaps 315) certainly has bulbs. Thinking about it, I find it surprising that on later disk drives -- RL's, RK07s, R80s etc, they used bulbs and not LEDs. By that date LEDs were easily available and reliable. -tony From bqt at update.uu.se Mon Jun 1 12:38:59 2015 From: bqt at update.uu.se (Johnny Billquist) Date: Mon, 01 Jun 2015 19:38:59 +0200 Subject: Panaplex display history In-Reply-To: References: <5568EE2F.2080807@gmail.com> , <5569F3BA.6050008@sydex.com> <556A01A5.6090503@email.wustl.edu> <556C7AC6.6040005@email.wustl.edu>, <556C7BF3.2090709@update.uu.se> Message-ID: <556C98B3.4050203@update.uu.se> On 2015-06-01 18:07, tony duell wrote: >> >> >> Thinking about it, I seem to remember seeing some picture of an 11/70 >> with bulbs as well, but all 11/70 machines I've seen or worked on had >> LEDs, so I suspect they might have had bulbs initially as well. > > DEC used little modules containing an LED and series resistor that were > the same size as the bi-pin T1+3/4 bulbs used earlier.

My 8/Es certainly have bulbs, while my 8/M and 8/F have LEDs.

The first "modern" drive that used LEDs that I can think of is the RA90. And then you didn't have the lamps in the buttons, but next to them, and then you had a 14(?)-segment 4 digit display to show more information.

But there was no reason to introduce illuminated buttons, was there? The older drives had separate indicators. So DEC made a change which essentially forced them to use less reliable, higher current, indicators. IIRC the R80 (and probably others) has a lamp test facility so that when you get a FAULT you can be sure that the bulbs are all working and that the indication is therefore genuine. LEDs probably wouldn't have needed that. I seem to recall that CDC at about that time had a pushbutton with a rectangular LED on the surface of the button. That seemed quite a neat device. I am sure DEC could have come up with something. -tony From bqt at update.uu.se Mon Jun 1 12:53:57 2015 From: bqt at update.uu.se (Johnny Billquist) Date: Mon, 01 Jun 2015 19:53:57 +0200 Subject: Panaplex display history In-Reply-To: References: <5568EE2F.2080807@gmail.com> , <5569F3BA.6050008@sydex.com> <556A01A5.6090503@email.wustl.edu> <556C7AC6.6040005@email.wustl.edu>, <556C7BF3.2090709@update.uu.se> , <556C98B3.4050203@update.uu.se> Message-ID: <556C9C35.1070500@update.uu.se> On 2015-06-01 19:42, tony duell wrote: >>> Thinking about it, I find it surprising that on later disk drives -- RL's, RK07s, >>> R80s etc, they used bulbs and not LEDs.

But there was no reason to introduce illuminated buttons, was there? Looks nice in a dark room. :-) And some of the lamps would flicker when the disk were busy, while others reflected state. The RL02 for instance. The LOAD button could be in or out. In addition you had the lamp inside, which indicated if the drive was locked. You could only open the lid when the lamp was on. And when you pressed the LOAD button, that lamp went out, but the lamp in the unit button only came on when the drive was up to speed and had passed the initial head load. So button positions and lamps provided a combination of indications and operational details. On the RA8x drives, you have a write protect button, but the drive can also become write protected through a software command, so the lamp can go on with the button not pushed in. But that don't really answer your question, as they could definitely have placed the lamps separate from the buttons instead of putting them inside. You could say that it was a space saving solution, but as you have plenty of empty real estate on the front of the drive anyway, there was no real need for this space saving. > The older drives had separate indicators.

Well, we know one works in that it was running while we were there. Booted RT-11 off the fixed platter and then had to do some file deletion on cartridges. As for the other two drives, we'll have to see as Rob finds time to check them. We won't be surprised if they have problems as they may well have earlier drives replaced by the functioning one. The power supply had been pulled out of one, but was still around. There are two spare logic boards for the drives, but I expect problems are more likely to be in the HDA area. Should we end up finding a fault and succeeding in a repair, will let you know.

The bottom 4 lines of text having color bleeding is normal, even on an Apple color composite monitor. The monochrome 80 column screen looks pretty good too. Well, you're right! The text looks like crap on an analog CRT, too. I updated my blog post with a few more pictures. Now I'm even more curious about the reports I've heard about having trouble with video conversion, since the first cheap converter I tried seemed to work OK with an Apple //c. Of course, it still lacks a tuner for the TV-connected computers, but I got the impression that the Apple II series was especially picky about its video converters. Maybe there's a different program I should try running that does weird stuff with video modes, like some game with particularly interesting graphics? I'm also interested in seeing what the converter will do with composite video tapped out from a Color Computer's innards. I seem to recall that it had some screwy video modes that required the user to keep hitting the reset button until the colors weren't swapped. -- Mark J.

Color is always the problem with converters. The cheap composite to VGA converter I have will show all the color as monochrome stripes. It has problems with the Apple II and the Atari 800, but works perfectly fine with the Commodore 64, since the C64 doesn?t use the same weird tricks to get color. I?ve read that sometimes they can handle the Apple II color fine, but there?s no way to distinguish which actual model you?re getting since the cases are all identical and they are sold by Chinese sellers. Most likely early ones worked and later ones don?t. A couple of times I?ve also been tempted to drag my NTSC Apple IIc & ZX Spectrum with composite PAL mod down to a Best Buy and try out some small LCD TVs to see if there?s a model that can handle both. This one looks exactly like yours, but it?s even cheaper! I wonder if it?s the same? http://www.amazon.com/dp/B009A6PJKQ Heh, found another one for 3 bucks more with Prime, so I ordered it.

Most of the functionality appears to be in a single QFP, probably with a central ground/heat slug based on the vias on the bottom side of the board.

(The part number for the distribution panel is 70-19964-00.) (I'm pretty sure the cabkit, which is technically for the DZQ11, will also work with the DZV11, since they are documented as both using the BC11U cable.) I don't have to have the cable (which is a BC05L-xx, which I'm pretty sure is the vanilla 40-pin cable), since I'm set up to make them, although if the panel comes with one, that's fine, of course. Anyone know of a source for any? I looked online, none on eBay, Google showed one dealer with one, but they wanted like $50 each.

But if the NDA would disallow that, then I'd either need to close part or all of my design, or pick out a different tuner option. As far as the crazy cat lady project, as I was trying to explain earlier.. my $.02 which maybe redundant to your own thoughts: VIDEO ADC/DECODER You can certainly use an off-the-shelf part as there are 47 from 5 companies on Digikey alone in solder friendly packages. However if the classic machines you are targetting are producing a clean conforming NTSC_M/J, PAL_B/G/N, or SECAM signals, stock video decoders on most converter boxes would work perfectly already. I doubt you will have much luck with the NDA process explaining a hobby cause but worth a try. Even if you are successful, make sure the parts you are looking at are readily available in 10s and 20s quantity through a distributor chain at a reasonable cost. That may be a second hurdle if it's fairly exotic. What SiLabs part are you looking at? I can't find any recent video decoder offerings. GENERIC ADC/DSP ANALYSIS This is the harder path to go down. You will need a symbol rate of at least 54 Mhz from a single or two interleaved ADCs to have a shot at at least 50% phase accuracy (NTSC = 13.5 MHz). There are some relatively inexpensive options, but I suggest getting a lot of input from folks and other reference designs on the best way to build an analog front-end for composite. And only do composite/S-Video. There are already commodity solutions for stepping down broadcast RF frequencies to base-band. After that, you will need something fairly hefty at the start to find the characteristics of the signal and align the sampling. Then you just need to track clock drift and adjust a VCXO. Straight-forward in hardware, but I doubt many people will have the experience to add new software support for and fix bugs when they occur. So set expectations on your time early with respect to project support. SOC/ZYNQ/MARKET The fact you mention ZynQ throws up a few warning flags for me. It's probably overkill, it's expensive in low quantities through normal distributors, and it's not very hobby friendly. $65 for a '010 alone + DDR3 + BGA assembly would drive the resulting cost for you to make these boards well beyond $200. And your market is small - vintage computing folks w/o a CRT on a limited budget. Considering that, you probably should not try to build the processing core yourself. Run the ADC output or the video decoder Bt.656 output into a stock board like a Parallella, BeagleBone Black, or other EVM that has the processing power, HDMI output, and input interfaces you need; especially to start with. Then go full custom later. -Alan From chrise at pobox.com Tue Jun 2 10:46:29 2015 From: chrise at pobox.com (Chris Elmquist) Date: Tue, 2 Jun 2015 10:46:29 -0500 Subject: 8-bit Computer TV Channel Use In-Reply-To: References: <067BC6A1-2ADE-4874-A5C7-7BE633B6669B@fozztexx.com> <1FBDF44A-108D-4FDD-A336-DED30FD2332E@nf6x.net> <14BC9739-CC9E-495E-854D-DD57D2A91583@fozztexx.com> <756A4E08-7DDC-43D3-B10E-685B1252C358@nf6x.net> Message-ID: <20150602154629.GA5160@n0jcf.net> On Monday (06/01/2015 at 07:39PM -0700), Mark J.

Most of the functionality appears to be in a single QFP, probably with a central ground/heat slug based on the vias on the bottom side of the board. The top of the chip appears to have been sanded to remove the markings. I ordered one too after seeing your pictures. It seems like the Amazon price is not exactly deterministic-- I got mine for $11.90 yesterday and the same link today shows it at $14.48. Perhaps these are commodity priced, you know like corn :-) I will try mine with various DEC terminals, Heathkit H19/H89 and several other composite monochrome sources. Your 80 column display looked really nice. I had similar results with a GBS-82xx converter driving into a VGA LCD but I would say the text is not as crisp there likely due to the additional conversion back to analog VGA which your solution would eliminate.

Right. It's the "clean conforming" part that I have heard is the issue, though my initial success with the first sub-$20 converter I tried makes me wonder whether the perceived desire for Crazy Cat Lady is overstated. > I doubt you will have much > luck with the NDA process explaining a hobby cause but worth a try.

It's Si2137, with 130 pieces on hand at Mouser. But for all I know, they might have bought one tray of somebody's leftover production parts, with no more to appear. If I use the part, I'd consider putting the tuner on a separate board with the expectation that the Si2137 might dry up without warning. > GENERIC ADC/DSP ANALYSIS > > This is the harder path to go down.

I'm looking at a $2.30 commodity part for the tuner, which is probably 1/10 the cost I could roll it myself. But having a tuner is an important feature, as most of the computers I'd want to target have RF/TV outputs, and I'd want to support them without requiring modifications to pull out composite. > After > that, you will need something fairly hefty at the start to find the > characteristics of the signal and align the sampling.

My expectation would be that I would make the design open, but then be very surprised if anybody rolled their own improvements rather than making sad puppy eyes and asking me to add support for their favorite neglected computer. :) > > SOC/ZYNQ/MARKET > > The fact you mention ZynQ throws up a few warning flags for me.

Agreed. But I do use them in my day job, so there's a strong familiarity factor. And another thing that I find compelling is that pushing FPGA + firmware updates would consist of instructing users to place one or more files on an SD or MicroSD card, rather than buying a programmer cable and installing a vast FPGA development platform, without me needing to roll my own FPGA reconfiguration solution. If I rolled my own with a cheaper FPGA + microcontroller, it might end up cheaper in BOM cost, but maybe not by a large margin. And one of my challenges would be for me to try to get the BGA routed on a 4-layer board by careful selection of unused I/O pins and the largest-pitch package available. It's not uncommon to use 16 layers to escape those beasts with all pins used (and I've done it myself, on more cost-insensitive designs), but that wouldn't fly for this product. I won't know if I can do it until I try. It's promising that there are Zynq 010 dev boards in the $100 range. -- Mark J.

So my guess that those parts are a leftover tray with questionable future availability might be unpleasantly accurate. I'm still interested in pursuing a cheap tuner design to see if it goes anywhere. Even if it turns out that some existing composite to HDMI converter satisfies everybody, I think there would be interest in a small, inexpensive standalone RF demod to get composite video out of vintage home machines without internal mods, and Crazy Cat Lady could morph into that. Maybe it would involve custom hardware, maybe it would be a TV tuner dongle operated in SDR mode plugged into a Beaglebone with custom software, maybe it would be a general purpose SDR design that happens to be well-suited for video demod... figuring that out is the fun part for me. -- Mark J.

For the general ADC route, I would put a PLL/clock synth on the board in-case you have gross alignment errors on the incoming signal. The input should be a multiple of 13.5 but you never know with clock short-cuts on early systems. It's been a while since I've looked at the Zynq PLLs, but usually they aren't designed for large bit depth M and Ns. You will need one anyway to generate a 12.288 for audio and the different output dot clocks. I've used TI CDCE906 and IDT's VersaClock IIIs for this in other projects. A VCXO is probably the simplest choice for clock recovery. Simple PWM and RC filter to the tracking pin will allow you to slew the clock 150ppm or so. As far as ZynQ, I would throw up a few warnings about the 300 MHz DLL drop-out point on DDR3 and difficulty of routing. However I'm reminded of the Zed board and their placement of by-pass caps in a pattern that looked 'pretty'. Certainly not a beginner project, but you don't sound like one. If you wanted to start with Parallella boards instead, I have a couple trays of the SamTech mating connectors. I can send some your way. For SoC, it depends on the power you need to look at the signal. If I were faced with the requirements you have created, I would start looking at the Atmel SAMV7x line. The EVMs are starting to ship publicly and it's the first to market for the ARM M7/Pelican core. It's has more DSP performance in a small micro than most DSPs a generation ago. With OTG and integrated highspeed USB PHYs, you could also ship the frame buffer updates to a PC and support USB stick firmware update. Might be a nice alternate solution to HDMI scaling. And it's super cheap. A number of smaller FPGAs might do the trick depending on how complex your RTL pipe-line is. The usual suspects, Spartan 6, MachXO2, and the new MAX10 from Altera. -Alan From t.gardner at computer.org Thu Jun 4 12:47:00 2015 From: t.gardner at computer.org (Tom Gardner) Date: Thu, 4 Jun 2015 10:47:00 -0700 Subject: DEC Runoff to any modern format conversion or DEC MSCP protocol specs Message-ID: <004701d09eee$75cd0580$61671080$@computer.org> Hi I have multiple DEC Runoff (.rno extension) files for the manual on DEC's MSCP protocol.

A much closer relative is Unix ?troff? format, which apparently goes back to something in Multics called ?runoff?. Fancy that.

Doesnt it support postscript output? Not any version I have ever seen; they all produce plain lineprinter output (with overprinting for things like underlining). You can of course take the formatted output and run it through a simple postprocessor like pstext. Some versions of troff can produce PostScript (current Linux or Darwin ones, for example) so if you can do runoff->troff then you have a direct path to PostScript. But you?re right, if someone would offer to run an actual RUNOFF on the sources, that would be a good approach.

The online help says it can produce output for an LN01, LN01E or LN03. While these are laser printers, as far as I know, they are nothing like postscript printers. I did a quick test and the output looks to me like 8 bit ANSI escape sequences and text. Regards, Peter Coghlan.

(4-plane visual (overlay) via X-server on MS-WIndows) Message-ID: <557097DF.5080105@y42.org> [also posted to comp.graphics.x today] Hello Folks, I'm trying to get an application that currently uses a local display on an ancient DEC Alpha workstation with a (for the time) mid-to-high-end graphics controller (ZLX-E2) to instead use an X-server running under MS-Windows. The application is complaining that it cannot find a "4/5-bit visual". It almost certainly wants to use this visual for an overlay, as the application displays moving objects superimposed on a map. On the original hardware, xdpyinfo tells me: > [...] > supported pixmap formats: > [...] > depth 4, bits_per_pixel 8, scanline_pad 32 > [...] > screen #0: > [...] > depths (4): 8, 12, 24, 4 > [...] > number of visuals: 21 > [lots of other visuals here, but no 4-plane except for the following] > visual: > visual id: 0x36 > class: PseudoColor > depth: 4 planes > available colormap entries: 16 > red, green, blue masks: 0x0, 0x0, 0x0 > significant bits in color specification: 4 bits and "xprop -root" tells me: > [...] > SERVER_OVERLAY_VISUALS(SERVER_OVERLAY_VISUALS) = 0x36, 0x1, 0x0, 0x1 As you can see, there seems to be exactly one overlay, whose visual id (0x36) corresponds to the single 4-plane visual listed by xdpyinfo. When I use the above commands to retrieve the capabilities of the MS-Windows X-server (Exceed, in this case), xdpyinfo does not list a 4-plane visual at all. "xprop" lists lots of overlays, 24 in total, all of them 8-plane visuals. The MS-Windows box is running Windows-7 (64bit) and has a Nvidia Quadro 400 GPU. I used the "Nvidia Control Panel" to set "Enable overlay" to "on" in the "Manage 3D settings" section. Also, in the Exceed X-server configuration I enabled "OpenGL", and within that enabled "Overlay Support" and "GLX 1.3 Support". I conclude that the MS-Windows SW/HW system (X-server, MS-Win GPU driver, GPU) cannot offer 4-plane visuals. However, I don't know what system component(s) is/are the cause the problem. I have tested VcXsrv, Reflection-X, Exceed (with 3D option), X-Win32 and even the ancient DEC Pathworks X-server eXcursion with no success. I'm working on getting an evaluation copy of PTC's MKSTools X/Server. Of the X-servers I've tested, Exceed seems to offer the most configuration parameters. I'm not even sure the Quadro 400 can handle 4bpp "visuals", or whatever MS-Windows calls them. In fact, I wonder if any modern hardware offers 4bpp capability. On my Linux box with a GeForce GT 430 I don't have any 4-plane visuals, and xprop doesn't mention any overlays either. I'm somewhat confused about where overlays fit into the X scheme. I have seen lots of references to overlays in an OpenGL context, however the Alpha seems not to have any OpenGL capability: GLX is not in the list of extentions printed by xdpyinfo. Can someone clear this up for me? Am I correct to assume that the GPU must support 4bpp in order for it even to be possible for the X-server to propagate a 4-plane visual to a client? If yes, how can I determine if a GPU supports 4bpp? Nvidia is very sparing with the information in their specs for the Quadro 400 GPU. Assuming I can find a GPU that supports/offers 4bpp, does anyone know an X-server product/project that can provide 4-plane overlays? thanks, Rob From richardlo at admin.athabascau.ca Thu Jun 4 15:53:28 2015 From: richardlo at admin.athabascau.ca (Richard Loken) Date: Thu, 04 Jun 2015 14:53:28 -0600 (MDT) Subject: X11 expertise on ancient HW sought...

There's some stuff called "Rubber Renue" sold for just that purpose. Basically, it's a mixture of methyl salicylate (oil of wintergreen) and xylol.

Its syntax is almost a complete emulation of DSR (Digital Standard Runoff) and it is very compatible with previous versions of Runoff. The document and help file for this version can also be used for DSR. The intent of this program is to support com- plete scientific word processing to produce publication quality output. It has been used to produce thesis, progress reports, and scientific pa- pers here at Rice University. This version allows complete control of any special printer available via user definable escape sequences. In addition a macro facility allows text or sequences of commands to be abbreviated to a single label. If the printer has the correct features, then variable spacing,subscripting, superscripting, and equation formatting are possible. By properly defin- ing escape sequences the user can support different printers in a tran- sparent fashion. In other words the same input text will print in identical fashion on different printers with different control codes and escape sequences. All written in glorious MACRO! Mark.

Ain't that the truth. I had a 11/725 with a working RC25 back in the 1990s, and I've semi-recently replaced it with a different 11/725 that did not come with a removable cartridge so I've not been able to spin it up to test the internal platter. Hopefully it works, but if it doesn't, (see below). > Fortunately for an 11/23 or 11/83 there are lots of alternative drives available. There are. Unfortunately, for Unibus machines (11/725 especially), there are not as many alternatives. One I've seen is to nibble a chunk out of the rim of the cover skin (to prevent pinching) and run a BC-11-A Unibus ribbon cable out to a BA-11 and stick any number of controllers in that, such as an easy-to-find-but-power-hungry UDA50. Also good for adding more serial, etc. Just put RAM in the CPU box and leave all the peripherals in the external BA-11. Not supported by DEC, but it works fine. I've also heard of people using Emulex and other 3rd-party SMD and ESDI controllers. Those aren't too expensive. Unibus SCSI, OTOH, is not common, but a joy if you can find one. -ethan From mattislind at gmail.com Fri Jun 5 02:31:23 2015 From: mattislind at gmail.com (Mattis Lind) Date: Fri, 5 Jun 2015 09:31:23 +0200 Subject: PDP-11/44 M7098 ECO #7? Message-ID: I have been given a PDP-11/44 and I was running through all sorts of diagnostics to check out the machine. It seems to work fine except for the trap test KKABD1 which fails at 23252. It passes an earlier version of the same trap test. The listing (thank you J?rg) is at: ftp://u58104846-pub:open4you@ ftp.j-hoppe.de/fichescanner/bw/gh/AH-F623D-MC__KD11-Z__11-44_TRAPS__CKKABD0__(C)79-82.pdf It tells me that my M7098 board is missing ECO #7. Anyone knows of a list of ECOs for the PDP-11/44. I think I have searched everywhere I can think of but haven't found it.

I have only one cartridge myself, and it's probably bad. Somebody needs to come up with a hack to spin up the Winchester part alone (hint, hint :-) >One I've seen is to nibble a chunk out of the rim of the cover skin (to prevent pinching) and run a BC-11-A > Unibus ribbon cable out to a BA-11 and stick any number of controllers in that Doesn't the 725 have one of the regular bulkhead connector panels on the back? The one with the modular screw in plates? If so, ISTR that there's a cable clamp one that will clear a BC11 cable. In any case, I have no need for such foolishness :-) I have a perfectly good 730 too, with a BA11-K expander in the next rack. It works great, and that configuration (with the 730 instead of the 725) was even supported although uncommon. I should go out in the garage and check how the UNIBUS cable is routed for you. Besides, the cool thing (for me, at least) about the 725 was the packaging. Any replacement drive would have to fit inside the original box to suit my taste. The best option I've come up with is an SMD UNIBUS controller (I have just exactly one!) and a small SMD drive. There were some small SMD drives that I think would fit inside the 725 case. The front panel wouldn't be right, but it's better than nothing. As you said, SCSI would be better, but I don't have a UNIBUS controller. What I'd really like is to build a "LESI disk emulator" that could just plug into the AZTEC controller, but as far as I've ever been able to determine, DEC never documented LESI. Or at least none of the documentation ever escaped. BTW, my 725 is missing the outer sheet metal skin. The previous owner apparently didn't think it was important and discarded it. If anybody happens to have an extra VAX-11/725 skin, I'd love to know.

Yeah. I have one. It's Qbus. Nothing wrong with it - that's about the going price from what I've seen, but it's not Unibus. -ethan > On Fri, Jun 5, 2015 at 5:31 PM, Toby Thain wrote: >> On 2015-06-04 8:49 PM, Ethan Dicks wrote: >> >>> ...

(I'm not sure what the arrow is supposed to indicate). Which way around to install them, or which port is #0, would be my guess. I've seen a similar arrow on the dist panel for the DLV11-J (which also comes in two distinct variants).

Apparently there is nothing off the shelf; I have sent copies of one of the two manuals to three of us who indicated they would try something and will be happy to do the same for anyone else. AFAIK, DEC RUNOFF is only similar to other runoffs in that it uses a period "." at the beginning of a line to designate a command. Most . commands span the single line but some have multi-line and/or multi file implications. E.g. Something like .HL 1 Overview of MSCP Subsystem Converts to

Overview of MSCP Subsystem

Most of the conversions are obvious but some are a bit more complex, in particular the .require command which apparently assembles the chapter files into a book. .referencepoint command which is some form of anchor, perhaps for an index since so far it always seems to follow a HL command so maybe .HL 1 Overview of MSCP Subsystem .referencepoint overvw_mscp_sub Converts to

Overview of MSCP Subsystem

With the ID being called from a Table Of Contents built to include the full name and page number It looks like a multipass converter would be the way to go. Anyhow this is a bit beyond my current coding skill but if anyone else wants to try a converter I'd like to work with them Tom -----Original Message----- From: Tom Gardner [mailto:t.gardner at computer.org] Sent: Thursday, June 04, 2015 10:47 AM To: cctalk at classiccmp.org Subject: DEC Runoff to any modern format conversion or DEC MSCP protocol specs Hi I have multiple DEC Runoff (.rno extension) files for the manual on DEC's MSCP protocol. I'd like to convert them to a modern format. The manual is dated circa 1992 incorporating ecos thru MSCP23-4 and is revision 2.4 (or later) of MSCP. What appears to be an early version (Apr 1982 rev 1.2) is at http://www.textfiles.com/bitsavers/pdf/dec/disc/UDA50/AA-L619A-TK_MSCP_basFn s_82.pdf I've searched for a convertor without much luck, there is a VMS Pascal converter at https://www.ctan.org/tex-archive/support/rnototex which converts to LaTex which can then be converted to pdf, but I don't have any DEC equipment. Anyone know of a converter or perhaps other already converted manuals at other revision levels (e.g. rev 1.2 at link above)? If not, anyone running VMS Pascal or OpenVMS v6.1 (or later) willing to try a conversion to LaTex? DECs Runoff is a markup language that sort of looks like an early HTML, so I suppose I could try a grep conversion to HTML, or just strip out the markup. Any other ideas?

No-one else wanted it, it was luckily only about and hour from me. I have been slowly working on it, it now feeds and registers a card correctly but my main problem is dirty relay contacts it seems. I have zero experience as-well... The 024 and 026 were introduced 48 years before I was born so I honestly am tackling a new beast heh. But I have been slowly making progress :) Really they are complicated in their mechanics, the only overwhelming thing with the electronics are the sheer number of wires, especially to that keyboard! For the keys I am going to try and 3D print semi close replacements until I am lucky enough to find original keys... I wish those looking for an 029 luck, they seem to be quite rare in comparison to the 026 as I have previously said. The only reasoning I have found for this is because IBM seem to have sold off the rest of their inventory of 024/026 Keypunches and parts to a company called MAI which kept them going well after they were intended... Mine had a service booklet that says it had Service coverage affective in 1970 for the US Army. This was 6 years after the 029 was released in 1964 and 21 years after the 026 was introduced! Not to mention I think I have seen a service log entry into the early 80s (I have absolutely tons of these service logs)!! I do although have the desk for an 029... Likely will never find the guts but oh well it makes a cool desk until then :) I got that for free from a set of the desks, the rest were trashed that one was actually nice, but they used a bunch of trashed 029's to barely get one working so it wasn't put to waste I suppose. I at-least stopped the good desk from hitting the trash. -Connork On 6/6/2015 2:39 AM, Brent Hilpert wrote: > On the one hand the 25K is ridiculously excessive; on the other I'm surprised you were able to obtain one for so little, even in poor condition, and there was so little bidding. > > Replacing the missing keycaps may be difficult, but it otherwise looks quite recoverable. > > > On 2015-Jun-05, at 6:21 PM, Connor Krukosky wrote: > >> That has been posted up for a LONG time and will likely NEVER sell at that price or at any offer since this guy seems to think its made of gold. >> It's less rare than an 029 seemingly anyway.

Message-ID: <5572C7C1.1050202@btinternet.com> Hi All I have recently produced a number of high quality custom PDP8/e front panels. They are full size reproductions of the original. The production methods are exactly as used in circa 1971. They are not photographs. The front has the two colours plus the white each done with its own silk screen and the back has the intense black with the clear circular areas for the lamps to shine through. The inks were matched and made to order. The acrylic blanks with the cutouts for the keys were also a custom order. I did the artwork, The four screens were made and the printing done by two young ladies with very good graphic arts skills at 'Squegee & Ink Ltd' local to me here in Newbury UK. I have some photos but they do not do justice to the pin sharp lines and intense colours. The panel fits the bezel and the switches on the key + lamps board line up.

No. However, it is substantially more difficult for an X server to present a visual that the hardware doesn't support, which is probably why the server you have doesn't do it. Well-behaved clients must be prepared to handle whatever capabilities the server presents; the problem here is that the client you have handles the server you have by complaining and dying. Depending on what other capabilities the client is using, you might be able to get the overlay effect using colourmap hackery with comparatively small code changes.

You probably do not need a GPU. The era when 4-bit visuals were common was full of dumb memory-mapped framebuffers; modern CPUs are fast enough that they can probably fake up a 4-bit overlay visual and still run at least as fast as the hardware your client software was designed to run against. I'm not sure how hard it would be to do. My X server hackery has never included faking something the hardware doesn't support, so my experience is rather limited in that direction. But I've done DDX layers for at least three widely disparate framebuffers, and I feel reasonably confident what you want could be done. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mouse at rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B From robert.jarratt at ntlworld.com Sat Jun 6 07:36:40 2015 From: robert.jarratt at ntlworld.com (Robert Jarratt) Date: Sat, 6 Jun 2015 13:36:40 +0100 Subject: DEC Runoff to any modern format conversion - MORE INFO In-Reply-To: <017501d09fea$f7989500$e6c9bf00$@computer.org> References: <017501d09fea$f7989500$e6c9bf00$@computer.org> Message-ID: <015101d0a055$70361040$50a230c0$@ntlworld.com> I have had a go with some of Tom's files but I have encountered some problems.

Depending on the cost, hacking the X-Server might be an option. I have presented MS-Windows as a given here, but in fact I could also use Linux.

The main IBM keypunches (026, 029, and 129) are sort of like Teletypes - yes, they have respectable value, but there are still a whole lot of chances to get into a "right place, right time" situation and get them for nothing. At this point, I have started to pass them by, unless it they are super easy to get. The variants, on the other hand, are very difficult to find, as are verifiers and non-IBM keypunches. -- Will From snhirsch at gmail.com Sat Jun 6 12:31:20 2015 From: snhirsch at gmail.com (Steven Hirsch) Date: Sat, 6 Jun 2015 13:31:20 -0400 (EDT) Subject: Troubleshooting a N* Advantage Message-ID: My Advantage decided to stop booting from floppy disks (the only media it is capable of booting). At first it threw random disk errors, then progressed to the point where I get an immediate "Hardware Failure" diagnostic on screen at power up. If I reset and hit 'Enter' it starts the disk drive comes right back with a "?" prompt and LOAD SYSTEM. I've checked the obvious: - Power supply voltages are good - Pulled, cleaned leads and re-seated 52 very tarnished 4116s - Cleaned and reseated all other socketed parts. A lot does seem to be working. Display is fine. I can enter the mini-monitor and poke around. Keyboard is being read properly. I accidentally found an undocumented diagnostic (enter mini-monitor with Ctrl-C and enter 'A'). This displays the disk controller status registers. The only activity is the sector mark pulse, so something is responding to disk data. Any advice from other Advantage owners or those familiar with the beast would be appreciated. Interesting data point: I replaced the 8035 slave processor with a newer 8035 from the parts bin and none of the I/O operations it manages worked at all - no keyboard no disk activity. Is there perhaps something special about the older part? I'm not aware of any major differences in this part through the years, but you never know. -- From nf6x at nf6x.net Sat Jun 6 12:37:19 2015 From: nf6x at nf6x.net (Mark J.

I'll be happy to do likewise for big stuff that I don't want myself. I figure that for large items like these, the bidding results will depend on whether there are two potential buyers close enough to pick up the item.

Not for sure, but it might be useful to know that Bonner Lab RUNOFF (which was mentioned before) actually have .style headers and .ebb (.enable bar), so those might be figured out from there. There might be some more that Bonner Lab RUNOFF have that you might be looking for.

What I don't understand though is this: are these extensions particular to Bonner Lab, or are they an implementation of Runoff commands that just aren't in any of the versions I happen to have?

Message-ID: <5573771B.3070009@btinternet.com> Hi Guys Thanks for all of the enquiries for panels. I have ten in total. One I have here (as in photo) and the other nine are in the drying rack at the silk screeners. My photo does not do them justice. The screening is a lot sharper and clearer. On Monday I'll go and get the rest of them (10mins down the road) and sort out shipping. I'll let one of the nine go to each of the first nine firm orders. Please send your order to me at rodsmallwood52 at btinternet.com. I'll respond with the total inc. shipping. Payment will be by PayPal. and I'll ship on receipt of payment in full. I'll also instigate another batch of ten. The plexiglas suppliers size the panel and do all the cutouts. They then ship direct to the silkscreeners who are (very) local to me. Total time to second batch availability circa 7-10 (business) days. If I get orders for more than ten then I'll bump up the second batch size accordingly. If there is a demand I'll do other 8's or 11's front panels that use the same plexiglas and silk screen technique.

It allows the .bb (.BEGIN BAR) and .eb (.END BAR) commands to take effect. Without .ebb the .bb and .eb commands don't affect the output. A .dbb (.DISABLE BAR) command will cause the .bb and .eb commands to be ignored. The .style header is a fancy one that controls which levels of headings (1-6) have section numbers before them, which are made into run-in headers or centered headers, and so forth.

I had a hunch that the "Hardware Failure" diagnostic might be a memory parity error (the Advantage is one of the few machines I've seen of this vintage that has a parity chip on each bank). Starting swapping in some extra 4116s and finally brought it to the point where CP/M signs on, the drive steps to the directory track and dies with a an error code: T 1 D 1 S 0010 According to the documentation: T1 = Sync byte not found D1 = Drive A S 0010 = Sector 10 (decimal) It's almost certainly not bad media. I tried several different (and previously working) bootable diskettes with exactly the same results. When I try to boot the GDOS demo diskette, it clears the screen, starts making a repetitive "buzz" from the speaker and hangs.

I should have said with regard to .style headers that I think the problem is the following syntax, it has lines like this: .style header (level=1,before=1,after=1,norunin,firstcap) Which don't appear to conform to the definition of the command in the manual, although there could be more syntax defined somewhere in the manual that allows this, but suffice to say runoff doesn't like those lines. Another example is .EBB, in the file it is: .ebb '|' And it complains about the bit after "ebb", the manual doesn't seem to allow for the bar character to be specified Overall, it looks like some special version of runoff to me. I tried the /DEC_INTERNAL switch, but it made no difference.

Someone mentioned -12's and -15's? I don't (yet) need any -11 ones, although at some point, I might need an 11/20 one (I have a line on an 11/20 that spent a lot of time outside, so its front panel is sadly very faded). The thing we really need to find now is a source for the special switches that DEC used in the front panels of the machines of this generation. Electrically, they are just standard SPDT switches (usually two-position, although for some - e.g. Deposit/Start - they are momentary-contact spring-loaded); the real issue is the mechanical fastening, which uses a special front plate (albeit on a standard micro-switch body). I have a number of different ones in my machines, from various manufacturers, but I have had no luck tracking down new ones through the part numbers on them (they seem to be DEC part numbers, or adaptions thereof). I have asked a number of people, but nobody seems to have spares/extras. Anyone know of a source?

Do any possibilities involving Linux occur to you? Nothing specific, because I don't use Linux - and, given what I've seen in my brushes with Linux-land, I am inclined to doubt that anyone has built out-of-the-box support for such a thing. But I would hope Linux is capable of presenting a dumb 24bpp memory-mapped framebuffer to userland, in which case an X server could be built which presents whatever it wants to clients and then composits it all into the framebuffer, with the main CPU if necessary. (This would make colourmap changes comparatively expensive if the underlying hardware is TrueColor instead of DirectColor, but only _comparatively_ expensive - I'd guess such a change could probably be done within a single vertical retrace.) However, as I said, this is not something I've ever personally tried, so I have only wild guesses at how easy it would be. At least with Linux on the (X) server host, I become much more confident it's just ("just", hah!) a SMOP. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mouse at rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B From geneb at deltasoft.com Sun Jun 7 09:21:58 2015 From: geneb at deltasoft.com (geneb) Date: Sun, 7 Jun 2015 07:21:58 -0700 (PDT) Subject: Need Dos bootable 5 1/4" floppy with binary or hex editor In-Reply-To: <55739C4A.5000700@jwsss.com> References: <55739C4A.5000700@jwsss.com> Message-ID: On Sat, 6 Jun 2015, jwsmobile wrote: > For Pick folks (Mr. F15) I don't know the sysprog password, and need to null > it out. > Cool!

Unless I'm really confused, "EXCHANGE" is not a format. EXCHANGE is a program under VMS to read/write RT-11 format file systems, which is what you usually had on the FE media. However, if you actually have EXCHANGE create an image copy of a tape/disk, and it actually is 512 bytes larger than the device, then I guess EXCHANGE have some sort of image dump format with some extra block with some meta-data. See if you can spot the RT-11 file system in there.

That's something I can look for. My home-grown RT-11 filesystem finagling utility barfed on my "suspected good" raw image, but that could very well be a bug in my own code. I'll dig in with a hex editor tonight and look for the filesystem header blocks. I definitely know that this is the case for the VAX-11/78x and VAX-86x0 machines. And you use EXCHANGE to access the files. I haven't properly looked at the 11/750, 11/730 or 11/725, but I don't think EXCHANGE understands anything else but the RT-11 filesystem. As far as I know, that was EXCHANGE existed for. It might be able to read DOS-11 tapes as well. (If we talk about pure 1/2" magtape.)

DEC standardized on that format for console media, even though there is no actual PDP-11 involved in the 725/730/750. And EXCHANGE has the ability to create "virtual" media images on disk. The CONSCOPY script creates a virtual TU58 image file and then copies all the files from the real console TU58 to the virtual copy. Why the copy has an extra 512 bytes, I don't know. I agree with Johnny - dump out the image and look for the RT11 directory.

He will send us some as a donation. We put some heat-shrink tubing on to stop further damage. Warren repaired and tested the M706 Teletype receiver. We put it back in the PDP-12 and put the borrowed M706 back in the PDP-8/I. The donor brought another M706/M707 pair, so we tested them and then installed them. We have two working serial ports in the PDP-12. Warren is making an Arduino based programmable baud rate generator for this system. We ran more diags. The 8/I Instruction Test #1 & #2, and the random JMP, JMP-JMS, ISZ tests work OK. The LINC Tape-Quickie test and the Memory Address test fail after running OK for a few minutes. We tested all of the G221 Memory Selectors, and they are OK, so the memory address decoding is probably working OK. This may be a case where the processor is sometimes doing the wrong thing when comparing numbers, and the rest of the hardware is actually OK. Debugging this will be the project for next week. The donor dropped off more documentation, spare parts, LINC tapes containing the DIAL operating system, and an RK05 disk pack that likely contains OS/8. We will make image copies of the LINC tapes and the disk pack. -- Michael Thompson From rodsmallwood52 at btinternet.com Sun Jun 7 09:39:39 2015 From: rodsmallwood52 at btinternet.com (Rod Smallwood) Date: Sun, 07 Jun 2015 15:39:39 +0100 Subject: PDP-8/e front panels.

The switches are marked Patent 3217112 They are a normal slide type modified with a U bracket to allow the attachment of a lever arm to operate the switch when toggled up and down. They come in three types ; hold up or down to connect and close to connect. The lever arms are molded from a tough type of plastic (nylon or PET ?) They have maintained their bright colour over the years suggesting a tightly bonded structure. There appear to have been attempts to produce copies but the only results I have seen, have been disappointing. 3D printing looks hopeful but not for production quantities, The tooling for injection moulding (thats how they were produced back in the 1970's ) is too expensive. At this time I'm just doing replacement panels for 8/e's and maybe other 8's Long term a light weight resin bezel and maybe (very maybe) a lamp and switch panel + microprocessr to emulate a real 8.

So I have worked on it some, and I have a new version here: http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/MP01239_MSV11-P.pdf which I feel is much more legigible, and is also a lot smaller (3.5MB instead of 36MB). The default page size is quite small (I have no idea why, I didn't do the re-conversion to PDF, I don't have Acrobat), but if you blow it up to about 300%, it still has good resolution at that point, and it's quite readable - all the signal names, pin numbers, package numbers, etc are quite legible. It doesn't have as much resolution hidden away as the original, but for most purposes, it seems quite acceptable (in fact, more so in some ways, given the increased legibility). I was interested in producing something readable, and easier to manage, and I think this new version succeeds at both. For those who are interested in the details of what I did (because I've seen other FMPS scans with this issue, and it might help someone down the road), after first saving all the pages as individual images (like I said, I don't have Acrobat, so whatever I did had to be done with something else - and I'm not sure Acrobat can do what needed to be done to make them legible, anyway), I started out by trying to simply increase the contrast. That didn't do anything (at least, with my image tool). Looking at the page images under magnification, I discovered why: the areas of ink (lines, letters etc) were actually (in the scanned image) a stipple of white and black pixels, which together produced the (un-readable) light gray printing of the original. So the contrast enhancement knob didn't do anything - each individual pixel was already quite light, or dark. So I used something called an averaging tool (which takes small groups of pixels, and averages them together), with a small averaging box size (I used 2x2), which converted the ink areas to a uniform grey; I could then use contrast enhancement to bring the printing up. I then reduced most pages to 40% of the original size, since the originals were scanned at 600 dpi, in 8-bit/pixel grayscale, and were pretty huge. (I didn't go that far on a few pages - the PCB images - which could use the higher resolution. Also, if you want the full resolution, the original scan is of course still available.) In addition to making the images smaller, this actually increased the crispness of the printing, since the reduction sampling process got rid of a lot of the jaggedness that the previous steps had left. I finally converted the resulting images from 8-bit/pixel grayscale to 1-bit/pixel black-and-white; on inspection of the two side-by-side, this lost a tiny bit of definition, but I felt that the reduction in size was worth it, plus to which my image tool has compression for 1-bit/pixel B+W TIFFs, but not for 8-bit/pixel grayscale TIFFs, so I won doubly on the size.

Message-ID: <5574AF05.8030905@gmail.com> Hi all -- The lovely HP 3082A terminal I've been using with my PDP-11/73 has started exhibiting odd/annoying behavior today. The 3082A is also known as the "Industrial Touch" terminal, it's a compact unit in a rugged housing with an EL display, built in keyboard, and a touchscreen. At powerup, it normally gives a few short beeps and starts normal operation. As of today, it gives one continuous beep for 31 seconds (I timed it), after which it works fine -- until the next time it needs to emit a beep (a ^G, for example) and then it beeps for 31 seconds again. This is, to be quite honest, intolerable :). The manuals on hpmuseum.net are limited to configuration/user manuals and the brief troubleshooting it recommends actually *does* mention the continuous beeping symptom, but gives no suggestions for causes, and suggests as a fix to (a) try turning it off and on again (I've done that...) and (b) replace the terminal (can't do that). I've also tried resetting the terminal config (hold down Help + . at powerup) and this has no effect. The terminal passes all built-in self tests. Anyone happen to have any experience with these, or know where a service manual might be found? If I at least knew what the 31-second beep signified I could start looking...

The trouble appears to have been a simple timing issue: tu58em includes some time delays which run afoul of the 730 console's very aggressive timeout checking. After patching in a command line flag to disable them, my 730 console seems to be happy with tu58em running on my MacBook Air over an FTDI USB/RS-232 converter. I've also tweaked the FTDI's driver settings to make sure that latency is minimized, but I'm not sure if I changed it significantly from the default. But the console appears to time out if the tape drive takes 20ms or more to respond to the initialization sequence, so every millisecond might impact reliability. With the console working and loading up a version 57 11/730 console tape image that I found online, I've been trying to boot the machine up. When I try to boot from either the R80 or RL02, I get error message "%BOOT-F-Unexpected Machine Check". Does that error message mean anything to the VAX experts out there? This machine was believe to be working before time + transport, and I'm trying to bring it up for the first time since I got it. I still have a lot of learning curve to climb, but I'm excited to have made more progress. -- Mark J.

That would be me. I have one -12 with a smashed front panel, and one -15 with the nasty XVM sticky plastic sheet front panel that would look much better with a plexiglass replacement!

The problem is if you would do that, the heads on the empty cartridge would load and smack together. The RC25 has one motor spindle, one positioner, and two pairs of heads. I suppose if you found a way to wedge the upper and lower arms of the removable cartridge so the heads weren't damaged, you could use the fixed platter alone? If you didn't, it would be as bad as forcing an RL02 or an RK05 to load with no platter mounted. -ethan From rodsmallwood52 at btinternet.com Sun Jun 7 23:01:48 2015 From: rodsmallwood52 at btinternet.com (Rod Smallwood) Date: Mon, 08 Jun 2015 05:01:48 +0100 Subject: PDP-8/e front panels.

In every fixed/removeable drive I have worked on (OK, never an RC25, but...) the heads for both the fixed and removeable disks are on the same positioner carriage. With the result that if you load the heads without a removeable cartridge in place, those heads will touch each other, which is a good way to ruin them. -tony From pbirkel at gmail.com Mon Jun 8 05:49:19 2015 From: pbirkel at gmail.com (Paul Birkel) Date: Mon, 8 Jun 2015 06:49:19 -0400 Subject: PDP-8/e front panels.

Ugh OK, I've never laid hands on one as I said; for some reason I thought the cartridge on these was a sealed unit containing the heads, like some IBM drives, e.g. 3340...

No, and I don?t think DEC ever made any drives like that. The removable cartridge drives are all variations on the RK05: one or more platters wrapped in a plastic shell that has an aperture for the heads to enter. The heads are in the drive. The RC25 was one of the last cartridge drives (before fixed drives came back in small sizes and exploding capacity), somewhat interesting because of its compact size, and very odd and hard to use because the designers threw in a fixed platter. Perhaps they thought that it was a good idea because it gave you double the capacity at modest extra cost, but in practice it made for a major pain in the software and operationally. paul From rodsmallwood52 at btinternet.com Mon Jun 8 09:18:46 2015 From: rodsmallwood52 at btinternet.com (Rod Smallwood) Date: Mon, 08 Jun 2015 15:18:46 +0100 Subject: Front Panel Update In-Reply-To: <20150608122141.GO21359@Update.UU.SE> References: <5575885D.4090109@btinternet.com> <20150608122141.GO21359@Update.UU.SE> Message-ID: <5575A446.8030105@btinternet.com> Yes several The originals have rounded corners.

Hmmm IBM used exactly the same trick - removable platter, with a fixed platter below it - in 1969 with rather larger platters on their 5440 disk for the System/3... I have one of these; have had various things to fix (some still unfixed!) but the disks have been entirely reliable.

The marking can be very small and inconspicuous, but it seems like good form to have one. Yes, I was going to mention this as well. The trick (which is not hard at all) is to make the marking declaring it a replica hidden from normal view, but in such a place where it would be discovered easily during an audit or inspection. And, yes, DEC panels did have minor variations in artwork. For example stock green PDP-12 panels come in at least two versions - early ones have lower case in the markings, but later ones do not. -- Will From ard at p850ug1.demon.co.uk Mon Jun 8 10:31:25 2015 From: ard at p850ug1.demon.co.uk (tony duell) Date: Mon, 8 Jun 2015 15:31:25 +0000 Subject: Rescue update: DEC RC-25s + / was Re: DEC cartridge ID In-Reply-To: References: <20150528040526.GA29544@Update.UU.SE> <20150528060218.GB29544@Update.UU.SE> <90C96986-E0F5-41C1-BF6D-BA7AD223CB44@cs.ubc.ca> <005401d09c8d$aa2afc50$fe80f4f0$@com> <00a201d09f43$99c47a40$cd4d6ec0$@com> <1B2934CD-53B4-4E2D-AD04-7D4B6AA47369@comcast.net>, Message-ID: > The RC25 was one of the last cartridge drives (before fixed drives came back in small sizes and exploding > capacity), somewhat interesting because of its compact size, and very odd and hard to use because the > designers threw in a fixed platter.

Many other compainess pulled a similar trick... The CDC 'Phoenix' (is that a 9648 or something) had a removeable pack containing one platter and 3 fixed platters. Capacity was 16MBytes per surface (or so), so the removeable pack stored 16Mbytes) (one data surface, one servo surface), the fixed part was 80 MBytes (5 data, 1 servo surface). Plessey made an RK05-a-like (same interface, linked to their version of the RK11-D, took same cartridges, same format, etc) with a fixed platter as well as the cartridge. Of course the HP7900 was like that too. I never really liked the idea. The main problem was you lost access to the fixed disk(s) while changing the removeable one. -tony From rodsmallwood52 at btinternet.com Mon Jun 8 11:00:07 2015 From: rodsmallwood52 at btinternet.com (Rod Smallwood) Date: Mon, 08 Jun 2015 17:00:07 +0100 Subject: Front Panel Update In-Reply-To: References: <5575885D.4090109@btinternet.com> <20150608122141.GO21359@Update.UU.SE> <5575A446.8030105@btinternet.com> Message-ID: <5575BC07.6040509@btinternet.com> Hi I did consider that and as there will be more that the few I had planned. I can do that. I thought I might call it a Replic8 or a Fake8 or Makan8 for the kit. I am some what flattered that my humble efforts at artwork could be mistaken for the real thing. Thinking back some forty years I seem to remember that whilst at DEC I heard that they (the panels) were made removable so OEM's could brand their own systems.

There have been various development since, and I figured I should encourage people who are using BQTCP/IP for RSX to upgrade to the latest release. A short list of changes: ICMP: . ICMP packets accidentally lost the source IP address informaton when returning information to a program. - Fixed. TCP: . User timers on TCP sockets could erroneously stop. - Fixed. . User timers now reset on completed reads, so that you do not get a timeout if you are constantly completing reads. . Sockets in Fin-Wait-2 could sometimes get stuck in that state. - Fixed. . If a TCP session got an RST, it could get into a bad state. - Fixed. . Added the ability to send URGENT data in TCP. (Receive ignores any URGENT flags.) . Added a special I/O function to read from TCP without formatting. DNS: . Improved stability of DNS client daemon code. FTP: . FTP client and server performance improved. . FTP server logging added. . Improvements in FTP server and client for handling files with implicit CFLF. . Implemented primitive handling of Unix file paths implemented in FTP server. This allows most web browsers to access FTP repositories under RSX. I also did some performance testing using FTP. FTP from a modern Unix system of BQTCP.DSK in binary mode to both RSX and 2.11BSD, running under simh on the same physical machine: 2.11BSD: 210s RSX: 141s From RSX (E11) to the same machines: 2.11BSD: 240s RSX: 137s I honestly do not know why transfer from RSX to 2.11BSD took longer than from Unix, but transfer from RSX to RSX was faster compared to Unix to RSX. I would have expected both to be slower or faster. But the numbers are interesting, and show that the RSX TCP implementation is doing fairly well, even through it goes through the DECnet ethernet driver, as compared to 2.11BSD which runs TCP/IP more "native". As usual, the distribution is available from: ftp://madame.update.uu.se/bqtcp.dsk ftp://madame.update.uu.se/bqtcp.tap ftp://ftp.update.uu.se/pub/pdp11/rsx/tcpip/tcpip.dsk The documentation is also available through ftp on Madame, or also at http://madame.update.uu.se/tcpipdoc I hope people will find this latest release useful, and my next project right now is telnet.

Its made to be a replacement for damaged front panels on real PDP8/e's I doubt it would fit anything else. There is a possibility of a lights and switches panel to go with it if we can solve the problem of the lack of the lever operated switches that are a feature of the PDP8 However its a case of if you don't have an 8/e now or are building one then this panel is not for you.

I've got both, with the front panel-less version connected (on occasion) to the front panel version as an expansion box. 8/F is identical except for color. There was a memory expansion box for the 8/L that is reminiscent of the front panel-less 8/M, though it has four field switches on the front and no key switch (the 8/M just had a key switch and a SW switch).

Got both an 8/M with a front, and an 8/F. I don't remember that there are any differences in color, but my memory might just have bit errors. Also not sure what the "extra markings" would be on the 8/F. As far as I can recall, the 8/F,8/M are darker than the 8/E, but I don't remember there being much else that differs, unless you count the model designation text.

Ah; the 11/05's (which is what I need switches for) use toggle switches (like I said, pretty much standard micro toggle switches, excepts for the front plate). I'm pretty sure the later 11's with complete front panels (40's, 45's, etc) used the same kind of switch. I was assuming all the PDP-x's of that era used the same front panel switch design, but apparently not. Or perhaps I'm mixing my eras a bit, and the slightly earlier ones all used the slide switch stuff (I just checked my KA-11 panel, and it uses slide switches). I think the 11/20 might have used the slide switches (its switch register looks just like the one on the -8M). Anyway, it seems like we all need both kinds! :-) Noel From rodsmallwood52 at btinternet.com Tue Jun 9 08:40:09 2015 From: rodsmallwood52 at btinternet.com (Rod Smallwood) Date: Tue, 09 Jun 2015 14:40:09 +0100 Subject: PDP 8/e Front panel Shipping Forecast Message-ID: <5576ECB9.7060105@btinternet.com> Hi Guys 1.

I?m not sure if that?s completely true. I remember a PDP11 (11/45 probably) at the University of Illinois, around 1975. It was used as a terminal controller for ARPAnet. The system was called ANTS (not sure what that stands for), and it had a custom logo panel for the top of the H960 racks, in red and yellow, showing large ants crawling all along the cabinets. Not allowing the logo to be changed would make sense, since that is one of the rules of trademarks: you risk losing a trademark if you don?t use it consistently, for example if you create or allow variations of what was registered. paul From classiccmp at crash.com Mon Jun 8 05:35:59 2015 From: classiccmp at crash.com (Steven M Jones) Date: Mon, 08 Jun 2015 11:35:59 +0100 Subject: VAX-11/730 %BOOT-F-Unexpected Machine Check In-Reply-To: <5DE0689B-A385-4E63-860F-1FCAD6CF6CC4@nf6x.net> References: <59C0D248-688C-4F76-9EFC-41CE4AFA5CBC@nf6x.net> <5DE0689B-A385-4E63-860F-1FCAD6CF6CC4@nf6x.net> Message-ID: <5575700F.3020902@crash.com> On 06/07/2015 10:02 PM, Mark J.

I think it's even harder than that - the firmware in the drive will spin down if it thinks the removable cartridge isn't working. Otherwise you could just put a bad cartridge in there and let it spin up, and empirically that doesn't work.

I have a 730 I'm going to > have to have a hack at at some point... Sure! I'll take this opportunity to document a lot of the different pieces that I had to dig up to get this all working. First, here is Don AK6DN's TU58 emulator: https://www.ak6dn.dyndns.org/PDP-11/TU58/tu58em/ It's a DEC computer life-saver! I started with v1.4j, and modified it to 1) build on my Mac and 2) remove some delays that caused trouble with the console firmware's very aggressive 20ms IDLE-IDLE to CONTINUE turnaround timeout. Don hasn't had a VAX 725/730/750 to test it against, and it turns out that the 730 didn't like it at first. I've shared my fork here: https://github.com/NF6X/tu58em Note that the master branch, which comes up by default, is Don's original tu58em code. My changes are on the nf6x branch. I believe that Don plans to update his original code based on this experience, but I don't know yet whether he will do it the same way that I did or take a different approach. Both his original code and my fork are likely to change by the time you get back to your 730. :) I got my console tape images here: http://www.heeltoe.com/download/vax/tapes-730/README.html I also put a copy of those images on my GitHub account, along with some other bits such as the extracted files from them: https://github.com/NF6X/VAX-11-730-Console-v57 I have an RL02 pack of the Customer-Runnable Diagnostics that came with my system, and appears to be compatible with the CRD tape in that set of console tape images. I don't have a way to image it yet, but when I do I will add the image to that repository along with the console tape images. In working with the images, I learned that the console boot tapes are in RT11 format, but they don't strictly adhere to the RT11 filesystem documentation. They have, variously, spaces or NULs in place of some key fields such as the first directory segment entry of the header block. That was causing my RT11 filesystem utility to blow chunks on them, so I added a hack to it so it can read them now: https://github.com/NF6X/pyRT11 I have not yet tried to boot my VAX with a console tape image that has been generated with my pyRT11 code, so I don't know yet whether they will like each other. I figure I may need to experiment with that at some point, for example to change the DEFBOO.CMD as appropriate for my system. I found some VAX-11/750 console tape images plus a bunch of other TU58 images here: http://iamvirtual.ca/VAX11/VAX-11-software.html Since I can't seem to boot up my R80 or my other RL02 pack (labeled "VMS53RL02SYS" on top) yet, I've been trying to bring up the VMS 5.3 Standalone Backup tape images I found there. No luck so far. I have never run a VMS Standalone Backup environment before, but I am blindly hoping that it will be a small VMS environment that will let me try to mount filesystems from my hard drives and see what, if anything, is on them. I would greatly appreciate any clues here, because I'm in unknown waters.

You get a "$" prompt and the only command which it accepts is "BACKUP". You don't get to mount anything as BACKUP will perform any mounting needed itself. I'm not sure but it is also possible that only BACKUP /IMAGE works. The typical way to do a fresh VMS install onto a new disk is to boot standalone backup (from a tape or another disk) and then use it to restore the "B" saveset of the VMS distribution onto the target disk. Then boot the target disk and answer the questions. If you manage to get standalone backup running and want to try reading existing filesystems or distribution media without risking overwriting data you want to keep, you could try something like: $ BACKUP /IMAGE /LOG device: NLA0: With any luck, this should back up the files on "device" to the null device and list the filenames as it does it. If it complains, try this: $ BACKUP /IMAGE /LOG device: NLA0:SAVESET.BCK /SAVE_SET but that variation probably won't work for distribution media as that will be provied in saveset form and you can't have a saveset as both input and output.

I think the rocker switches as seen on the KA10 and PDP-12 are slide switches with a rocker mechanism mounted on top.

The system was called ANTS (not sure what that stands for) "ARPA Network Terminal System". According to RFC-597, Illinois had both an 11/20 and an 11/50 (11/45 variant) running ANTS; other sites also ran it on an 11/40. > it had a custom logo panel for the top of the H960 racks, in red and > yellow, showing large ants crawling all along the cabinets. That could have been a local thing. At MIT, the first MIT-built LISP Machines, also housed in H960 racks, had custom logo panels reading "LISP Machine", with an illustration of a LISP two-part cell, with pointers (to other, un-shown, cells).

I don't have an 11/20 (yet!), but I had a look at the KY11-A manual (no print set online, alas), and it does seem to show (pg. 19) a slide switch. Like I said, the 11/20 switch array looks exactly the the 8/E and 8/M ones (except for colour, of course), which seems to support that the actual switch is a slide. Anyone out there have an 11/20, and can give us definitive info? Noel From nf6x at nf6x.net Tue Jun 9 10:15:18 2015 From: nf6x at nf6x.net (Mark J.

My goal here is to figure out what's on the R80 and that RL02 pack, boot them if possible, and extract all of the delicious bytes for archival and examination on my modern machine(s) (primarily Mac). I'm trying to boot the standalone backup tape images because those are what I found that have the same version number as the label on top of the RL02 pack, and are in a format that I can do something with at the moment. Now, the seller of the system stated that he last run OpenVMS 7.3 (if I recall correctly) on it, so it's possible that's what is on the R80. The issue that I'm having at the moment is that when I try to boot from either that RL02 pack or the R80, VMB.EXE reports "%BOOT-F-Unable to locate BOOT file". I don't know yet whether there's something not-right about the contents of the hard drives, or I need to configure something (?) so VMB.EXE knows what to look for. The boot scripts on the console boot tape appear to set up VMB.EXE by shoving numbers into some registers prior to loading it, and I have not yet located any documentation about what the numbers mean. I can just see that they're different in each of the scripts. I've only tried the non-conversational boot scripts so far, since I learned about what the xxnGEN scripts were for after my last experimentation session. I wonder if I might be able to back up the hard drives to an absurd number of emulated TU58 images, so that I could then examine those on my modern machine? I could probably back up onto magtape, but I don't have another means to read the tapes yet. I have another tape drive (which needs repair) that I'll eventually include in my PDP-11/44 restoration, but that's a big project, far in the future. I wonder if the VMS5.3 standalone backup might know how to back up to some network device? I have an ethernet card in the VAX, so that might be a way to get data off the machine for examination. Any suggestions or clues would be greatly appreciated! I'm still learning how to tell the chickens from the eggs. -- Mark J.

No luck so far, but that may still be a tu58em compatibility issue, since I think I'm pushing it into untested areas. Doing a backup of the R80 onto emulated TU58 images seems like it would be pretty painful (if it's even supported by the standalone backup), but it's the only potential path to extracting the data that I've come up with so far, using things I have on hand. > >> If so, another option might be to make a fresh installation onto a blank RL02 (I think I have one), so I could then boot from that and try to examine what's on the R80. > > I do not think you can install VMS on an RL02. It's too small. I think I saw reference of doing a "tailored install" onto RL02 media in a software installation manual (presumably cutting out lots of stuff to make it fit), but it's a moot point without having suitable installation media on hand. -- Mark J.

There can be more than one system root on a VMS system disk, typically one each for different nodes in a cluster, maybe under [SYS0], [SYS10], [SYS11] etc and standalone backup can sometimes be found under [SYSE], if installed. "Unable to locate BOOT file" may indicate that you are not reading the correct system root or it may indicate that the disk is not bootable or maybe something entirely different. I am not well up on the 11/730 and I hope someone more familiar with their system specific details will chime in. On some other VAX machines but probably not an 11/730, the [SYSE] root would be booted by entering something like: boot /R5:E0000000 or maybe: boot /R5:E000000 or maybe even: boot /E0000000 or boot /E000000 > The boot scripts on the console boot tape appear to set up VMB.EXE by shoving > numbers into some registers prior to loading it, and I have not yet located > any documentation about what the numbers mean. If it is like other VAX variants that I am familar with, the top eight bits (or maybe four bits - I forget which?) of the 32 bit number that ends up in register R5 is what selects the system root you end up attempting to boot. > > I wonder if I might be able to back up the hard drives to an absurd number > of emulated TU58 images, so that I could then examine those on my modern > machine? > That sounds plausable.

Another approach came to mind that might be a lot easier than swapping a humorously large number of virtual TU58 cassettes, or might be yet another goose chase. One of my last recent eBay purchases before I quit both eBay and PayPal in a huff over terms of service changes was a TK50 drive and both UNIBUS and QBUS interface cards for it. All of the pieces are unknown quantities, and I'll need to kludge a power supply and fabricate an interface cable, but the drive can theoretically be plugged into my 730. If the 5.3 standalone backup knows about TK50 drives, then I may be able to try backing up whatever is on the hard drives to TK50 cartridges. Next, if I get a TZ30 drive, I wonder if I might be able to plug it into my Sun Ultra 60 running Solaris 8 (since that's my workingest computer with both a SCSI interface and a familiar UNIXy operating system), and then use that to slurp data off the backup cartridge(s) for further analysis. Does this approach sound plausible? Unless somebody happens to know that the TZ30 is incompatible with generic SCSI tape support on UNIX boxen, I think I'll contact the same seller I bought the TK50 from and see if they have a TZ30 sitting around. Yet another approach might be doing the same scheme with my system's existing magtape drive, and then trying to get my hands on a SCSI magtape drive to plug into my Sun. But that would involve shipping a much larger and heavier piece of equipment. -- Mark J.

Even if it's for VMB.EXE for a different VAX-11 machine, the one for my 730 might follow the same register conventions.

For my money, there ought to be one always, though careful handling in a controlled environment can probably get away with skipping them. Shipping is where the worst stresses occur, of course, so is the most important. I've received a number of tapes for imaging over the last few years, and I don't think a single one had anything to keep it packed. One such tape had slipped an outer chunk of the pack around the inner rest, producing a hard crease. Needless to say, there was a read error there.

Cool. I'm looking for one now.

It may have had some treatment to make it have the tactile adhesion you felt, but it left zero residue on the tape despite the adhesion to the mylar backing on the tape. When you stretched it it lost the property to stick to the tape, by the way, so shrinkage may be the culprit if they quit working.

There were several competing systems for hanging tapes. There was one that used hard plastic "bands" that were pretty wide (perhaps 1.25") that would crack if you dropped them on the floor. I've run into tapes with 5 leaders spliced on, one right after the other. And you'd be sure to get grief from your operator if you took one of those stiff leaders with a notched end and bent it double. I remember when the self-threading vacuum column drives were introduced. The usual procedure was the clip off the last inch or two of the leader before using them. Of course, if you carried the same tape between auto- and manual-threading drives a lot, that leader could shrink pretty quickly. --Chuck From nf6x at nf6x.net Tue Jun 9 17:27:59 2015 From: nf6x at nf6x.net (Mark J.

Preferably with 6250 BPI capability. Doesn't need to be fast or fancy; just needs to be working-ish. An alternative would be to look for a cheap Fujitsu M2444AC tape drive (often seen with Sun badges). They have Pertec interfaces, but it is probably easier and cheaper most of the time to find a Pertec tape drive interface for a DEC system than a SCSI interface, and they can be interfaced to ISA bus PCs. They are built like tanks and weigh around 200 pounds, which is why they can sometimes be had for cheap if you find one within driving distance because no one would want to pay to ship one. You don't do eBay any more, and asking over $300 is way to much, but here is what the look like for reference: http://www.ebay.com/itm/191583247197 I have picked up a couple in the $50-$100 range. Maybe you can find one on a somewhat local Craigslist page for cheap.

Varian is a microwave equipment company; I have one of their TWTs sitting on my H960 at home. Vacuum equipment, I could believe that. But yes, Varian made a 16 bit minicomputer; I had a handbook for it at one time (now lost, I suspect). And if memory serves, the reason is that there was one in the Computer Science department at the University of Illinois where I studied. I remember nothing about the architecture, other than the fact it supported user microprogramming. Possibly the OEM PDP8 predates that device. Or possibly it wasn?t enough of a competitor for DEC to stop doing OEM business with Varian. paul From paulkoning at comcast.net Tue Jun 9 17:47:11 2015 From: paulkoning at comcast.net (Paul Koning) Date: Tue, 9 Jun 2015 18:47:11 -0400 Subject: Blue tape retainers In-Reply-To: References: <55775F5E.8080808@sydex.com> <55775B6E.7080607@sydex.com> <20150609215708.7ADCFA585A6@yagi.h-net.msu.edu> Message-ID: > On Jun 9, 2015, at 6:01 PM, Mike Loewen wrote: > > On Tue, 9 Jun 2015, Mark J.

That sounds right. It?s the same stuff used for DECtape; we called those LBTs (?little blue things?). They work for 1/2 inch magtape provided the backing is glossy, not the matte stuff that some manufacturers used. I believe it?s the same stuff that you can find in window decals, like the ones of animals I had as a 4 year old. paul From jws at jwsss.com Tue Jun 9 17:57:36 2015 From: jws at jwsss.com (jwsmobile) Date: Tue, 09 Jun 2015 15:57:36 -0700 Subject: WTB /WTT DEC TZ30 and/or 1/2" open reel SCSI magtape drives In-Reply-To: References: <40EEBAEF-C8D7-422C-942E-A8E1603B4FE2@nf6x.net> Message-ID: <55776F60.7050808@jwsss.com> On 6/9/2015 3:44 PM, Glen Slick wrote: > http://www.ebay.com/itm/191583247197 > I have picked up a couple in the $50-$100 range. I had two of those which came with Sun 4-280 systems. Hamilton used them for doing custom Pal and prom stuff in their offices and I got the systems there. I suspect that some such systems were broken up if these guys have the drives. They also had the oddball SMD drives I asked about 2 or 3 weeks ago. thanks jim From nf6x at nf6x.net Tue Jun 9 17:59:58 2015 From: nf6x at nf6x.net (Mark J.

I'm looking for a SCSI interfaced drive so I can hook it up to my Sun Ultra 60, running Solaris 8. I don't run any ISA bus machines other than a 5155 Portable PC and a very crappy old 386 box dedicated to running ImageDisk, and my Sun would be much easier to use for this purpose, I think. It's also just new enough that it's not hard to get it talking to my current machines over the network, so it makes a nice bridge machine. I already have a magtape drive on my VAX, and was pleased to see it pass the diagnostic tests this weekend. It's a TU80. It hooks up to my VAX with a couple of 50-pin connectors... Hmm, maybe it has a Pertec interface, so another option might be to find a Pertec to SCSI adapter and use the same drive on multiple systems? I also already have a front-loading Kennedy drive with a Pertec interface which is earmarked for use on my future PDP-11/44 project. It needs some work, as it lost hub drive in one direction shortly after I got it. Once I repair it, using it with a SCSI to Pertec adapter would also eliminate the need to shipping yet another magtape drive around. So based on your comments, let me amend my request to say that I would also consider some sort of SCSI to Pertec interface. Thanks! P.S.: For those of you who don't mind clicking on a Twitter link, here's a picture of my VAX system as I was working on it this weekend, shortly before I took a break to let the room cool back down: https://twitter.com/nf6x/status/607650728459407360 The MacBook on top of the VAX is running tu58em. The Ultra 60 is sitting on the floor in front of the TU80 after a previous dead-end attempt to get tu58em running on it, before I figured out how to fix the issue I was having running it on my Mac. The two VAX cabinets are bracketed by my PDP-11/03 on the left, and my Nova 3 on the right. The DECwriter III is working nicely as the VAX console terminal. Oh, and my PDP-8M is sitting on top of the PDP-11/03 rack waiting for its next turn on the workbench. Photobombing the picture from the right is my IBM Mag Card II typewriter, also waiting for restoration. -- Mark J.

If I'm not mistaken, that drive has a Pertec interface, though, like the Kennedy 9610 that I already have, so I think I will let somebody else have a crack at it. That drive model looks familiar; we probably had at least one in the computer room I worked in during college in the late 1980s, and I may have done a tape mount or two on them! Hmm, I guess I have yet another option: Once I fix the hub motor drive in my Kennedy 9610, maybe I could just make my own interface for it. Maybe a small FPGA to handle the interface signals, and an off the shelf microcontroller (like a BeagleBone Black board?) to give it a UI and interface it to the outside world. Much more effort, but also more fun! I may be able to borrow a SCSI-interface magtape drive locally, but I still wouldn't mind having one of my own.

It works okay, but without detailed internals, it's hard to write a really good driver for it. > It's delightful for one, that's how! Think you might make more than > one of them, or share the plans?

So I've got an XC95108 CPLD consolidating the IF to a simple 8-bit wishbone bus affair. I'm currently using a PIC32MX795 to interface with that and provide the USB interface, but too much CPU and too little memory. A small ARM MCU would probably be better suited to the job.

Then in a couple of weeks from now I'll release a Kindle e-book version and a print edition. The PDF version is only $8 and can be ordered right now at the very primitive web site: http://www.abacustosmartphone.com. There's nothing to stop people from sharing or posting the PDF, other than me asking nicely: please do not do that. I am releasing the book early because I need the money. So what's in the book? It is the story of the evolution of mobile/portable computers -- how we got from the abacus to the smartphone. I wrote it in plain English for general and mildly technical readers. There aren't a lot of tech speeds-and-feeds; it doesn't explain how the computers worked or how to program them. It is almost entirely about who made them, why, and how they all improved on each other to incrementally move the ball forward. I think it's interesting. Some parts are very funny. Most of all, it's a story that until never was never told. - Evan From RichA at LivingComputerMuseum.org Tue Jun 9 19:53:21 2015 From: RichA at LivingComputerMuseum.org (Rich Alderson) Date: Wed, 10 Jun 2015 00:53:21 +0000 Subject: PDP-8/S In-Reply-To: <9093D680-CFF8-4822-800E-F1716269D920@gmail.com> References: <20150609115655.39274c53@asrock.bcwi.net> <9093D680-CFF8-4822-800E-F1716269D920@gmail.com> Message-ID: <539CFBE84C931A4E8516F3BBEA36C7AA01AEB18117@505MBX2.corp.vnw.com> From: Michael Thompson Sent: Tuesday, June 09, 2015 12:05 PM >> On Jun 9, 2015, at 2:56 PM, Lyle Bickley wrote: >> On Tue, 9 Jun 2015 14:27:57 -0400 >> Michael Thompson wrote: >>> I know of 17 PDP-8/S systems, including four at the RICM. >>> The RICM has an OMD8S data-break and memory expansion chassis for an >>> 8/S. >> Is there a registry somewhere for PDP-8/S systems?

Or is the entire tar archive effectively written as one continuous block which must be streamed with no repositioning? Yes, tar uses a fixed block size. You can actually tell it what block size to use. Most versions of tar I know use the -b switch for this. > I'm curious because I'm daydreaming about how to build a tape drive interface controller, and I wonder whether it might need to potentially stream an entire tape in one go vs. being able to safely assume some maximal block size. You can pretty much assume that no tape uses larger blocks than 64K. But you have to expect blocks of pretty much any size below that.

From what I remember as tapes are not the most reliable medium the process was to have the read head after the write head so the tape could be read and checked as it was written. If an error was returned the "system" would backspace, erase the bad block to create a "long gap" and the try again. Looking at the first MAN page for TAR I found it says it writes 20x512 byte blocks so 10K blocks, i.e. about 6.4" long. That means a "waste" of 10% of the tape in gaps, assuming the tape is perfect. You can write longer blocks but then the amount of wastage when you write a bad block goes up. So I guess to answer your question. Operating systems and tools expect a block level interface to tapes. You need to duplicate this in your interface.

When baking tapes with the Wright Line seals, I've learned to remove the seals. If you leave them on, the tapes at 58C, will often just fall right out the seal--the coefficient of expansion is much larger for the seals than for the tape reels.

I don't think it really is that you have a long gap when you rewrite a "bad" block per se. But you get long gaps when you stop/start. And a rewrite implies that you will get a stop/start situation. But in case you already were going stop/start, the gap will not be extended any longer. You want to stream the tape, meaning you both get short gaps, and also much higher transfer rates, as the stop/start really cause the tape to be slow. But for streaming mode to work, you need to feed data to the tape fast enough. And with that, I mean that when one block operation is finished, the command for the next one needs to happen very quickly, or else the tape will need to stop. This also means that you do not always have a short gap with an error free tape. The gap size depends on whether the tape was running at speed or not, when the write starts. > So I guess to answer your question.

The tach signal is a logic signal that pulses when the fan rotor is in a particular position. Some fans pulse once per rotation. Others are multiple times per rotation.

I can see from the IBM 2400 manual here:- http://bitsavers.trailing-edge.com/pdf/ibm/24xx/A22-6862-4_2400_Series_Magnetic_Tape_Units_OEM.pdf that write checking is accomplished by reading.

Some drives will back up, get up to speed, read the end of the previous block, switch from write to read when the irg goes by. The size of the irg can vary upwards from a minimum spec, at least in drives that try to stream, as they will keep the tape running for a moment in hopes that data will arrive to be written.

The Cipher manuals have some nice diagrams of tape layouts and tape movement that might be useful to you. Rewriting blocks on tape doesn't usually work; the spacing and such isn't quite repeatable enough. That said, I _have_ seen VMS rename files on tape. Yes, I was abusing it to see if it would work. :) > When writing a tar archive on a magtape from a Unix system, is the > archive written as a sequence of fixed-size blocks? Or is the entire > tar archive effectively written as one continuous block which must be > streamed with no repositioning? Tar will assemble blocks and write them. You can control the block size it uses. For 9-track, max block size depends a bit on system, but won't be above 64k. Some systems may only support up to 32k, or even 16k (Prime until the mid 80s). On ANSI or IBM labeled tapes, it's common to see records as short as 80 bytes (VOL1/HDR1 records), and shorter will work. I can't recall if there's a minimum. Terminology may be key to understanding all of this. On the 9-track tape, there are only a few kinds of objects: records containing data, inter-record gaps, erased areas, file marks, maybe noise records. The drive doesn't really care how much data is in a data record as long as it's shorter than the max size. There is no "fixed size record" on a 9-track tape. The distinction between "record" and "block" really exists in the host. For example, tar will gather up data from a file in file system sized units, e.g. 512 byte disk sectors. It thinks of those as records, and it assembles a block (-b option, say 5120 bytes) of a given size, and writes that to the tape. On tape, that block is just a 5120 byte record.

The E11/SimH .tap formats are dead simple, and relatively complete as far as capturing the arrangement of the bits on tape. They retain block size, actual data, file marks, and have a provision for indicating errors encountered when reading the tape. There was a discussion recently (simh list?) about standardizing the behavior of the error marks. The format doesn't have a mechanism for preserving metadata. In the SimH variant, record lengths must be even. In the E11 variant, they on't have to be. Otherwise, the two are equivalent. Using dd to read tapes to disk discards the block size information.

Mainframe/vacuum column drives were pretty darned reliable. I have memories of tossing about a half-dozen tapes into my big Samsonite briefcase and hopping a plane to travel cross-country routinely. I don't think I ever gave a thought to the reliability of the tapes. All in all, I think I had more problems with disk drives than with tapes. After all, didn't the IRS keep its taxpayer records on many many reels of half-inch tape for decades? Anent Pertec IFs: You have to understand that the Pertec interface is extremely simple-minded from a bygone day There are minor differences between manufacturers in the amount of information and features afforded by a given formatter, but generally, they do adhere to a common model. One thing that I've never cared for on *nix tapes is that the implementors never enforced any sort of standard tape label records. That can be very frustrating if the physical labels have dried out and gotten lost or if they're cryptic (e.g. "Joe's archive"). The label records on, say, an IBM SL tape can tell you a great deal about the tape contents. Even CDC on their NOS 9-track tapes tended to include ANSI labels before lapsing into the gobbledy-gook that was 6-bit display code and 60 bit words. Perhaps some UNIX(R) installations implemented an ANSI labeling scheme, but to be sure, AT&T didn't use any on their distribution tapes. --Chuck From nf6x at nf6x.net Wed Jun 10 10:15:20 2015 From: nf6x at nf6x.net (Mark J.

Chuck's comment about his USB to Pertec project woke up my own dormant Pertec interface project idea in my cluttered head. Hmm, this might be as simple as a BeagleBone Black board with an LCD board (both of which I already have), and a custom board with a cheap FPGA and the Pertec electrical interface. Yeah, I could probably implement the interface just fine in software using a fast microcontroller with lots of GPIOs. But FPGAs are what I know best.

Yes, other than some super-low end drives like Kennedy digital incremental and some Pertec drives, most drives were read after write. This required completely independent read and write hardware. I got a Pertec key to tape system surplus, and created a mostly software interface with very minimal hardware to read and write tapes on my S-100 Z-80 system. It would write, back up and re-read the block to verify. My recollection was there was only one data head, so it HAD to back up to read the data. My interface and the Z-80 was maxed out doing one or the other, so that was fine. >> If an error was returned the "system" >> would backspace, erase the bad block to create a "long gap" and the try >> again.

All tape systems I know of wrote essentially identical gaps whether doing start/stop or streaming.

I discovered there was a 10 us "reinstruct window" in the Datum controller, so if you could just get a new write or read operation loaded into the controller within that time, it would stream the drive. No way to do that with interrupts, but with double buffering and doing everything by polling, it was just barely possible to make it in time. It required error-free media, but if you had that, you could dump or restore a 40 MB Calcomp disk to 45 IPM Pertec mag tape in under ten minutes, including rewind. It was a total block for block copy, not a file by file copy, so the tape was pretty useless except for restoring again to a disk pack.

It's eminently possible to image tapes sanely on a unix box.

Ok, now three more questions come to mind: 1) Is it ever acceptable to mix densities on a single tape?

Long-record tapes frequently write past the EOT. On the old CDC vacuum-column (60x, 65x) drives, I'd sometimes add an extra BOT marker or two on a reel and start a new "logical tape" there. You just hit the "LOAD" button again while the tape was already loaded and it would space down to the next BOT marker. I don't know if anyone else's drives did that, though. I had my pet deadstart tapes with several different versions of a system on them. > 3) Did anybody ever go over to the dark side and implement copy > protection on magtapes, say, by deliberately including a record with > bad CRC that a normal driver+drive would not support writing?

Although, on the 7-track drives, you could toggle the parity, which would confuse the heck out of someone trying to read the tape. --Chuck From aek at bitsavers.org Wed Jun 10 11:40:26 2015 From: aek at bitsavers.org (Al Kossow) Date: Wed, 10 Jun 2015 09:40:26 -0700 Subject: Pertec Tape Drive Interface Musings In-Reply-To: References: <55782829.1090909@wulfman.com> <38D7A35C-F482-48F5-B2D6-281A6F0822C8@nf6x.net> <20150610150528.5E139A585A6@yagi.h-net.msu.edu> <38BD1731-9957-4E7E-843E-9AE77D17E266@nf6x.net> <55785BDC.1010101@bitsavers.org> Message-ID: <5578687A.7070905@bitsavers.org> On 6/10/15 9:12 AM, Mark J.

Len Shustek's copy of APL/360 has JCL that switches from 1600 to 6250 after the label is written. None of my drives can deal with that, incl the 9610. I've never tried programatic density switching on the 9610, which is supported. You also should keep an eye on the rubber capstan, they go gooey. I think I still have a box of capstan motors with the capstans on them from about a dozen drives I scrapped along with board spares. The 9610 was the only drive I've had luck with recently reading 800bpi tapes. It also is one of the better documented tri-density streaming drives. > 2) What's the scoop on a final record overlapping the EOT marker? Or even a new record starting after the EOT marker?

I seem to recall ALL applications put data after the EOT marker, should they fill the tape. So on a write you get an EOT reached status, BUT to get this you must have written past the EOT marker. If its non-labelled tape you write a tape mark, rewind and unload the tape and ask for another. It is up to the application program to know there is more data. Typically on a mainframe you wrote labelled tapes, so you needed to write a Tape Mark and the End of Volume Label and any other labels needed, then another tape mark, then unload and ask for the next reel. This usually goes after the EOT marker. For labelled tapes the label tells you if there is another tape in set. > > 3) Did anybody ever go over to the dark side and implement copy protection > on magtapes, say, by deliberately including a record with bad CRC that a > normal driver+drive would not support writing?

I'm not sure that my Kennedy drive will even allow that, but I don't know if that is universal. No, never OK. There is a format ID written OVER the BOT marker for 1600 and 6250 that tells the drive what the density format is. If you EVER see the density change, is is because a tape was partially overwritten at a different density, and then you've either read off the end of the re-written portion, or the last EOF was lost somehow. > 2) What's the scoop on a final record overlapping the EOT marker?

The discussion of .tap format to which I referred earlier largely seemed to revolve around the question of representing errors. Block length markers occur at the beginning and end of data records, unless they're file marks (length 0). On a read error, should one write a single error mark, a pair of them, should one include the busted data, etc. The answers are complicated by the SCSI habit of hoarding the damaged data.

The specs say there's supposed to be quite a bit of tape (10 feet, I want to say) after the EOT reflector. 2. It was not unheard of for broken applications to run a tape clear off the source reel. The drive reports the passage of an EOT marker. Few systems enforce any behavior in this regard. If you keep going, you keep going. At least until the tail comes off the source reel.

Bob extended it in Simh but behavior on read errors was never specified. John Bordynuik extended it in other ways in the tapes read by JBI, Inc., but I never found out what those extensions were. As was discussed on the Simh list, there is a bunch of information, like drive type and how it handles bad blocks, that should be in the tape image, but currently is not. I would think an error that returns no data would be a single error mark, but one with returned data should be two to handle the read reverse case.

It's not that you do not get a larger gap, but you can get a large gap even without an error. It's not an explicit error recovery strategy, but a fallout from having to stop, rewind, start and write again. >> But you get long gaps when you stop/start. > > Not on Vacuum Column drives. The columns provide enough mechanical buffering to start and stop within the Inter Record Gap. The mechanical buffering don't have anything to do with this. It's a question of how fast you get the tape up to speed across the heads. Now, admittedly, vacuum column tape drives have an advantage that you don't have to accelerate the reels that violently, since the vacuum columns gives you some time to speed up the reels. But the acceleration of the tape across the head is simply a question of friction of the drive wheel for that section of the tape, and the mass of the tape itself. However, since vacuum column tapes have a much higher tape speed across the heads than direct drive or spring tensioned tape drives, you get into the same cat and mouse game anyway. Acceleration of tape across the heads is the issue. How much tape will pass before you reach top velocity, and how precise is this? A larger gap allows for more variation. If the tape is already running at full speed, and you are just continuously writing, then you can easily control how long gap you create, and can create minimal ones.

One problem with "preserving errors" is that actual tapes do not have any indication that you have a tape error. In fact, many times you can recover a tape block by repeatedly read it. Eventually you might read it without errors. Not to mention how many tapes I have "fixed" by just folding the tape in the opposite direction where there have been a bend/kink in it. Easy fix. I guess it could possibly be useful to indicate a bad block on a tape, in order to preserve the numbering of all the blocks, and constantly giving a read error when used in a simulator. But it's kindof a weird reflection of a physical error into a virtual one.

I see no way to indicate that in the SIMH tape proposal. Earlier, I discussed how I've begun appending metadata to tape image files after the EOM indicator. Thus far, no simulator chokes on it. I really need to extend it. Right now it just indicates date, device information, notes from the person doing the reading and error messages during reading and file structure; e.g. 536 x 10240 bytes Filemark at block 537 3 x 80 bytes... Okay for now; save for a photo of the tape. Basically, anything known before and during reading of the tape and writing of the image. --Chuck From seefriek at gmail.com Wed Jun 10 16:01:33 2015 From: seefriek at gmail.com (Ken Seefried) Date: Wed, 10 Jun 2015 17:01:33 -0400 Subject: Looking for the Tek 465 of Logic Analysers Message-ID: Thanks for the input everyone.

Unless you've corrected the error, and can therefore write an error free image, _not_ marking the error somehow would be sort of cruel to the next guy. He might spend hours trying to _use_ the software that contains a damaged file without any clue, else.

Well, it could be, but if it were my show, I'd greatly extend the file format to accommodate not only the occurrence of a tape error, but also the "type" of error. Some formatters will raise the error flag during the transmission of a single frame in error. It might be useful to have some way to notate that--assuming that a controller is capable of recording such an event. In my case, it's mostly reading tapes and providing the data to customers. So blocked EBCDIC record files have already been unblocked with EBCDIC->ASCII translation. The .TAP file is provided as a reference in case of my getting something really wrong. If it's a UNIX(R)-type unlabeled tape, I extract the data between filemarks and assign a name of 0001, 0002 and so forth. --Chuck From jonelson126 at gmail.com Wed Jun 10 17:20:46 2015 From: jonelson126 at gmail.com (Jon Elson) Date: Wed, 10 Jun 2015 17:20:46 -0500 Subject: Alpha 4100 CPU fan In-Reply-To: References: Message-ID: <5578B83E.60802@pico-systems.com> On 06/10/2015 01:13 PM, Richard Loken wrote: > On Tue, 9 Jun 2015, Adrian Graham wrote: > >> Trying to source a non-DEC fan for a 4100 CPU since getting them in the UK >> is more and more tricky as time goes on.

Is the current version with the vertical switch position correct? If that is the case then the other one with angled switch position lines and dividers between groups of lamps must differ. The two colours are referred to as Amber and Terra Cotta. If they differ then they must have different names. As I am a bit colour blind the matching is done by our two screen printing ladies who are art graduates and qualified colourists. (in general females have better colour vision) If you have an example of a Type B ( angled switch position lines and dividers) that shows the difference in colour I'd really like a copy before we ship any type B Rod On 11/06/2015 08:01, Pontus Pihlgren wrote: > The color is quite different between the two.

Remote control and data transfer over TCP/IP in general may be much easier to set up than using GPIB, unless you already have gear setup for that. With the optional Ethernet interface the only practical difference between the 16500B and the 16500C is that you can use common and cheap PS/2 keyboards and mice with the 16500C while you need to find more rare and expensive HP-HIL keyboards and mice for the 16500B. Both are perfectly usable with neither a keyboard nor mouse. The downside of a 16500 series is that the value of the bare mainframe itself is often less than the cost to ship one. (Hey Ian if you ever want to move up to a 16500B I have some local to you...) For the 16700 series if you want a self contained unit with built-in display you need a 16702A or 16702B. The built-in LCD display is only 800x600. You can use an external monitor up to 1280x1024, or 1600x1200 with Option 003 installed. If you don't need a portable self contained unit and have the room to set up an external monitor a 16700A or 16700B should be cheaper than a 16702A or 16702B, plus you never have to worry about a display failing. One of the main differences between the 16700A/16702A and the 16700B/16702B is that the B version has a built-in SCSI CD-ROM, which comes in handy if you need to reload the system software. Otherwise you need to find a standard external SCSI CD-ROM drive. The 16520/16521 pattern gen modules and the 16530/16531/16532 scope modules are not supported by the 16700 series. You need 16522 or 16720 pattern gen modules and 16533/16534 scope modules. The 16700 series run on top of HP-UX 10.20. Once you factor in the shipping costs a 16700 series system might not be significantly more expensive that a 16500 series system. One limitation of the 1660A and 1660E series is the 4K sample depth. Depending on your application that may be a major limitation. The max sample depth varies on the 1670 series. I believe 64K and optionally 512K on the 1670A series, 64K and optionally 1M on the 1670D series, 1M on the 1670E series, and 64K and optionally 256K or 2M on the 1670G series. The E and G series have color LCD displays. The older series have monochrome CRT displays. The 16900 series are much more recent and currently a lot more expensive. An empty 16700A might be under $100 before shipping while an empty 16900A may be at least $500 before shipping. No 16500 series modules are supported by the 16900 series. The minimum supported 16700 series modules are the 16740A and higher, and the 16720A pattern gen which still sells for a premium. The 16900 series are based on Windows XP, or maybe Windows 7 on never mainframes. The good thing with all of these HP / Agilent analyzers is that all of the state/timing modules from the 16510 up through the 16752 and the 1650/1660/1670 series use the same 40-pin POD breakout lead sets. Starting with the 16753 modules they switched to the 90-pin POD connectors and the breakout lead sets for those are crazy expensive.

Woohoo! Wow... I'm rather surprised it can run something that new, and on a drive so small. I remember having problems fitting 6.0 on an RD53 (or was it an RD54?)

Of course, that assumes I can procure suitable installation media, or usable images with which to create it. Back in the day, we ran VMS 5.0 on our 11/730, because we needed a machine to link our product against 5.0 to support our customers on the same version.

The fellow from whom I bought the VAX mentioned that the included tapes were "load optimized", but I haven't successfully read one without errors so far.

The lines splitting the lamps into groups of three may or may not be present. 4. Diffences in colour from machine to machine (not verified yet) These could be related to 1. Date of manufacture 2. Place of manufacture 3. Serial No 4.

The donor brought another M706/M707 pair, so we tested them and then installed them. We have two working serial ports in the PDP-12. Warren is making an Arduino based programmable baud rate generator for this system. We ran more diags. The 8/I Instruction Test #1 & #2, and the random JMP, JMP-JMS, ISZ tests work OK. The LINC Tape-Quickie test and the Memory Address test fail after running OK for a few minutes. We tested all of the G221 Memory Selectors, and they are OK, so the memory address decoding is probably working OK. This may be a case where the processor is sometimes doing the wrong thing when comparing numbers, and the rest of the hardware is actually OK. Debugging this will be the project for next week. The donor dropped off more documentation, spare parts, LINC tapes containing the DIAL operating system, and an RK05 disk pack that likely contains OS/8.

Pardon my ignorance, I'm definitely not an expert and after sending this msg I am going to hide and pretend to be dead. However, I cannot see if you tried running your app on Linux-based X server. This might be easy to do and does not even require installing Linux. When I want to test some new hardware, I usually download GRML onto pendrive and boot from it. It's small, really, like half of CD-ROM. And it has relatively new X-server, plus few other things like compiler and Open Office, but in this case it doesn't matter. https://grml.org/ In case you go this way, it may make sense to read some manpages and experiment with options to server - different color depths, screen size (a.k.a. resolution). Perhaps there are some options to the client (DEC app) too, and maybe there is a match. BTW, is the problem related to just one app your customer wants? Can you run xterm from your DEC and display it on new X-server? I'm not sure what GPU has got to do with 4 bits per pixel stuff. I have always thought the problem with bpp is only when graphics chip doesn't have enough memory to handle, say, 1024x768 pixels, each containing 4 bits (16 colors mode), i.e. it has less than 384kB of RAM. And in such case, every app could have its own colormap, which caused display to blink in a psychodelic way. The last time I even bothered was probably when I added 1MB of video memory to empty socket on S3 video card, which allowed me to run X in 800x600 24bpp mode... about 17 years ago. So I think it would be a bit strange to have such problem today. Anyway, I'm definitely not an expert. Consider my questions as controls or noise, I have no idea what they are. Now I will run and duck. -- Regards, Tomasz Rola -- ** A C programmer asked whether computer had Buddha's nature. ** ** As the answer, master did "rm -rif" on the programmer's home ** ** directory.

There were two drives; one in front and one in back. The 16500A is capable of running only a limited subset of cards that were ultimately produced for the 16500 and runs a lot slower in general ... the system is built on a straight 68000 CPU. * The HP 16500B and 16500C use a different '030 based logic board and also were modified to boot from an internal IDE hard drive which is fairly easy to replace with a CF card and CF-to-IDE converter. The Startech one worked for me in my 16500B. I think the CF conversion on the 16500 makes for a great "no worry" situation for long instrument life. * The software to reinstall a HP16500B/C is readily available on the Web along with a bunch of other neat stuff for the platform ... inverse assemblers; the symbol table utility; etc. * Generally anything the "C" can do, the "B" can do and vice versa. The big difference between the two is that they switched from HP-HIL peripherals on the "B" to standard PS/2 peripherals on the "C", if you want to connect an external keyboard and mouse to use in lieu of or in conjunction with the touch screen; depending on what you have in your stash ... I happened to have a bunch of HIL mice and a HIL keyboard so HP-HIL on the "B" doesn't bug me. The "B" and "C" also support an option card that has a standard 10BT Ethernet interface on it, so you can control it remotely via X11, and SVGA out, so you can run an external display. Not necessary but something nice to look out for. * The 166x and 167x generally boot from Flash or something ... no hard drive... except the 1664 which was sort of a low cost "value model" for the line ... I think that boots from standard 3.5" HD floppies ... avoid that little guy. It's not bad, but limited ... you can usually find a 1660, 1661 or 1662 for about the same price with a bit of patience. * Pretty sure the 165x also boot from DS/DD floppies completely; no hard drive there either, AFAIK. The 165x is the first incarnation of the mostly-GUI interface that's later seen on the 16500, 166x, 167x and so on. * Once they went to the 16700 ... the switched the logic board again ... the 16700 is a little PA-RISC machine ... probably bears some relation to the 9000/712 if I had to guess ... IIRC the interface is a little different; more like just plain X11 running fvwm95 or something... the interface starts to feel more like you see on a contemporary LA if you were to go out and buy one brand new. IMO if you can find a good deal on a 16700, go for it, but it can be a little bit overkill for retrocomputing / hobby / light embedded work. The 16700 won't run some of the older 16500 cards, in particular, the two-card 400 MSa DSO option, which means if you want a DSO in there, say, you'd need to move up to the rather more expensive, 1 or 2 GSa single-card scope options. * IMO, the HP 1630 series and the Biomation K100 are pretty obsolescent and ... unless you already have one, or someone local to you is giving you one... I don't think they're really worth the cost of shipping unless you have some nostalgic attachment to a particular instrument. I like my 1662 and 16500B quite a bit and I wouldn't hesitate to recommend them to anyone!

If configured to form a cluster, VMS will normally wait for a short period for the other cluster member(s) to appear on the cluster interconnect (usually the ethernet network) before continuing to boot. Try leaving it for a few minutes and you may then get something like: "VAXCluster state transition completed. Initialization continuing". Or you might not. In a cluster, each node contributes a number of votes to the cluster. None if the nodes will do anything until a cluster quorum is present (more than half the number of votes usually present in the cluster). If the machine just sits there indefinately after loading the MSCP disk server, you probably don't have enough cluster votes to proceed and the best thing to do is perform a conversational boot which usually involves setting the least significant bit of register R5 to 1 before booting. How exactly to do this varies from processor to processor and I don't know how to do it for an 11/730. When you manage to do this and try booting again, you should get a "SYSBOOT>" prompt and you could: SHOW VAXCLUSTER SHOW VOTES SHOW EXPECTED_VOTES SET VAXCLUSTER 0 SET WRITESYSPARAMS 0 CONTINUE to confirm that the issue is with cluster votes, turn off clustering and proceed with the boot process. > I have plenty more experimentation ahead, including seeing what's on that > RL02 pack labeled something like "VMS53SYS" (if I recall correctly). > > My attempts to boot up the v5.3 standalone backup tape images I downloaded > still haven't succeeded.

This is likely newer than when the 11/730 was sold but I suspect that many an 11/730 would have been upgraded to this version while in service and ended their days on that version.

It happens because there?s some older mail clients being used which incorrectly parse the email address and create the general at classiccmp.org address when replying. The problem with the duplicate messages is because messages from the cctalk list are also relayed to the moderated cctech mailing list, and vice-versa. What happens is the messages from cctalk go over to cctech, get approved, and then get sent back to the cctalk list. From my understanding of the mailing list software being used, it doesn?t have any built-in facility to prevent duplicates by checking for messages with the same Message-ID, and would require someone to spend a little time to cobble a helper script together, but no-one has yet, so the message duplication has continued for a year or so now. -- Follow me on twitter: @FozzTexx Check out my blog: http://insentricity.com From h.j.stegeman at hccnet.nl Fri Jun 12 08:56:47 2015 From: h.j.stegeman at hccnet.nl (Henk Stegeman) Date: Fri, 12 Jun 2015 15:56:47 +0200 Subject: IBM 9335 doc needed.

The filing system is already consistent (that's one of the reasons it's boots so slow...) If you look for a copy of the VMS FAQ on the net, there should be a section on how to reset passwords. Here's a quick summary of one method: Go back to your conversational boot but this time enter: SET VAXCLUSTER 0 SET /STARTUP OPA0: SET WRITESYSPARAMS 0 CONTINUE When you get a $ prompt, enter (carefully, without any typos or you get to start all over again): SET NOON SPAWN /NOWAIT SYS$SYSTEM:STARTUP.COM When the startup finishes, press enter again and you should get back to your $ prompt. SET DEFAULT SYS$SYSTEM RUN AUTHORIZE MODIFY SYSTEM /PASSWORD= /NOPWDEXP /NOPWDLIFE EXIT LOGOUT Then login in. When you want to shut down gracefully: @SYS$SYSTEM:SHUTDOWN Regards, Peter Coghlan.

Avoid V5, though. I remember at the time that people was having serious issues with that version. V6 improved things again. I think DEC spent a fair amount of time to improve performance because of all the complaints about V5. V4 would also be good in some ways, but it's old and might feel limited if you want some modern software running... Not sure if V7 really is that bad with regards to speed. It's just that the 11/730 really is *slooow*.

After reading the other day about someone who was talking about VMS and the wish for DHCP, I actually decided that it was time that BQTCP/IP also got DHCP. So, without further ado - I cut a new release. One bugfix for a bug in the TCP state machine, which could get stuck, but otherwise the big reason is that DHCP is now implemented. Read the documentation, or ask me questions. The IPGEN procedure will create installation files for use with DHCP, but if you are upgrading from a previous version, you might want to make comparisons with the new command files, and merge any new stuff in, if you want to use DHCP. If you don't care about DHCP, then nothing needs to change in the current configs. DHCP tries to be clever, and handle some different options, but there are parts that I do not use myself, that I have not tested, or sometimes implemented. In such cases you might see some messages on the console. Pass such information on to me, and I can improve things. DHCP is written in PDP-11 C. If you do not have that compiler, you will not be able to recompile the code. Sources are provided, along with a binary that runs, and do not depend on any shared libraries. The DHCP code also makes use of some functions and interfaces to the IP stack and the interface drivers that others might find useful to reference to if they are interested in doing low level stuff with TCP/IP. (Such as reading/writing interface configs and routing tables.) As usual, the distribution is available from: ftp://madame.update.uu.se/bqtcp.dsk ftp://madame.update.uu.se/bqtcp.tap ftp://ftp.update.uu.se/pub/pdp11/rsx/tcpip/tcpip.dsk The documentation is also available through ftp on Madame, or also at http://madame.update.uu.se/tcpipdoc I hope people will find this latest release useful, and my next project right now is telnet (this time really...).

I can poke around at the file level with my RT11 filesystem tool: https://github.com/NF6X/pyRT11 In fact, the image I've used to boot the system isn't exactly the one that you fixed for me, but rather a new one I created using its files and bootblocks, with several scripts added to try booting different root directories. On the 730, I don't think I can modify R5 in the boot command. Rather, I would need to either manually type in the whole boot sequence manually, or create a new boot script off-system. I chose the latter, and made a bunch of them to try probing different root dirs on both the R80 and RL02 drives. BTW, standalone backup was not helpfully installed on E on my R80, so once I crowbar my way in, I'll try running a backup under the full OS.

My previous experience with it was just using it briefly in one or two classes, and running a canned script to perform backups as a graveyard shift operator (Great pay for a student!

Hmm, I wouldn't mind having one, with a matching 11/780... :) Back in the day, I really hated VMS for no other reason than I liked UNIX and embraced it with the natural snobbishness of a youth growing up in the computer environment of the 80s, where our computer was the "best" even though the other guy's "crappy" computer used the same 6502 running at the same clock speed (but mine really was the best, because it used a 6809 :) ).

I was imagining a scenario where someone hit reply to a corrupted message, generating a mail to cctalk but also a copy to General at classiccmp.org, which maybe somehow eventually got found and forwarded back to the list. I'm not getting as many duplicates as I'd expect if every moderator approved cctalk message came back via cctech. (Though I did recently get the whole PDP-8/S thread again.)

Our VAX-11/780 came with VAX/VMS Version 2 on it and the documentation had that quaint early Digital quality that looked like it had been printed on a Teletype Model 35. Our VAX 8600 came with VAX/VMS version 4.X - this leads me to suggest that you do not want a version contemporary to the VAX-11/730 (probably v2 or 3). We ran VAX/VMS version 5.5-1 for many many years on our massive great VAX 8820, VAX 4000 model 500s, some VAX 2000s, and my VAX 3100/30. Later releases of VMS 5.X are IMHO a good version. I have in my possession a Digital VAX/VMS software and documentation distribution on CDrom circa 1995 which includes VMS version 6.2. This is the complete standard distro from the time and came in two boxes measuring maybe 10 x 15 by 1 inch. I can send this to you for the postage if it is of any use.

Great to hear from you again! Still have those ARS33 teletypes? I must say, when I decided I needed to be an ASR33 owner again a year or so ago, it was a lot more expensive than those two that I got off the junkpile outside the EE stockroom in the Steele building at CIT! :) I seem to recall that you procured them for a PDP-8 restoration, but I don't recall which model (and it wouldn't have meant much to me at the time, anyway). > Our VAX-11/780 came with VAX/VMS Version 2 on it and the documentation had > that quaint early Digital quality that looked like it had been printed on > a Teletype Model 35. > > Our VAX 8600 came with VAX/VMS version 4.X - this leads me to suggest that > you do not want a version contemporary to the VAX-11/730 (probably v2 or 3). > We ran VAX/VMS version 5.5-1 for many many years on our massive great VAX > 8820, VAX 4000 model 500s, some VAX 2000s, and my VAX 3100/30.

So I'll experiment with 3.x if I can find installation media/images, but perhaps compromise on 5.x for something not too new, but not too primitive. Maybe I'll think about some sort of drive emulation to let me easily swap OSes, and to save wear and tear on the R80? My cage is full already with the ethernet card in there, so maybe it should grow a Unibus extension? There's an unused spot in the TU80's cabinet that might fit a chassis. > I have in my possession a Digital VAX/VMS software and documentation > distribution on CDrom circa 1995 which includes VMS version 6.2.

I would be interested in procuring both of those in order to put them on my "hopefully scan/image and send to Bitsavers and Archive.org before I die" pile.

Woohoo! Well done. The 11/730 is, to me, an interesting machine and one of only 2 VAX families that I would want to run (the otber being the 11/780 -- if I had space for it). To build a complete VAX on 3 hex cards using standard ICs is a good hack. There is one bit of design craziness in the 11/730 IMHO. The CPU control store is dynamic RAM. With the result that the CPU has to wait for the control store to be refreshed every so often. Why they didn't use SRAM is something of a mystery.... [...] > Eventually, I'd like to run an older version of VMS than 7.3 on it.

Of > course, that assumes I can procure suitable installation media, or usable images with which to create it. I think my 11/730 was running VMS 4.7 when it was shut down. A long-term project for me is to get my 11/730 running again. It was decommisioned and dismantled, and I have never got round to putting it all back together. The CPU box looks fine. It contains the 3 CPU cards, the RB730 disk controller (no FP730 though), 4 megs of RAM (2 DEC cards, 2 NatSemi ones), a TSU05 tape controller and a DMF32 serial/parallel card. All the ribbon cables have been removed, but I think I have them. Re-cabling that tray under the CPU is going to be 'fun' The R80 is in bits. The HDA is intact, locked, and the spindle pulley is taped down so it should be OK. I have the chassis metalwork (in need of minor repairs) with the power harnesses and switch/lamp panel fitted. Also the PSU, spindle motor assembly and the 4 PCBs (R/W, microprocessor, personality, servo) So far I have not unearthed the box of screws and internal ribbon cables or the drive belt. But those can probably be obtained (the belt might be a problem....) I have the half-rack to hold it, along with the slides -- somewhere. What to put in the top bay? Originally it was the TS05, which I do have. I am wondering how useful that is, and perhaps a Unibus expansion box would be more useful. But anyway... I've read all the applicable manuals on bitsavers. Did DEC ever publish the 11/730 microcode source? That would be interesting. Ditto the source for the 8085 firmware. And the R80 firmware. Was there ever a technical manual for the R80 (I have the service manual and printset, I am thinking of a theory-of-operation manual coverting the servo, etc) As I said, a long-term project. -tony From nf6x at nf6x.net Fri Jun 12 15:49:44 2015 From: nf6x at nf6x.net (Mark J.

Maybe I'll think about some In that era we received all our software on 9 track take and that material has been gone for decades. We never ran VMS v2, the machine was delivered that way in 1981 but ours was a Unix shop so they promptly tore it off and installed Unix V7 to be very quickly followed by BSD4.1. When the big boss told us we were going from Unix to VMS for administrative systems, everybody was quivering with rage including me and then I wound up babysitting the VMS systems for their entire tenure of some 15 years. I grew quite fond of VMS and have it running on my desktop even as I write this - it has been the last VMS system in the place for at least a decade. > I would be interested in procuring both of those in order to put them on > my "hopefully scan/image and send to Bitsavers and Archive.org before I > die" pile.

As somebody who has both and uses them (and has no later analysers), I have to disagree with you there. After all the OP was asking for the 'Tek 465 of logic analysers' which suggests not the latest instruments. The HP1630 and Gould K100D are easily fast enough for classic computer work (I've never had problems). They also seem to be a lot better documented than later analysers (can you get schematics of later HPs? I seem to remember they are not in the manuals). The probe interface is also documented and quite simple. While I recomend only getting a LA with the original pods, the ability to make custom pods has helped me on several occasions. The inputs to both those LAs are simple differential ECL signals, easy to hack about with. -tony From aliensrcooluk at yahoo.co.uk Fri Jun 12 15:57:27 2015 From: aliensrcooluk at yahoo.co.uk (Andrew Burton) Date: Fri, 12 Jun 2015 21:57:27 +0100 Subject: Amiga Fans References: <199AB4B0-54A2-46C6-B775-C8DD9E721546@pski.net> Message-ID: <00c401d0a553$a6539af0$97988d0a@user8459cef6fa> Hehe, I read about this a few minutes ago after receiving a message about it on another email list.

Bitsavers has the service manual, pocket service guide and printset. The service manual is, as I would expect, a module replacement level manual. It is useful because it documents the drive diagnostics, how to use the 2 hex switches and the LEDs on the microprocessor board. Trying to debug an R80 without that is going to be a lot of work! The pocket service guide is a quick-ref to the diagnostics and has a rather better internal cable diagram than the service manual The printset is of course the full schematics. Alas no PROM dumps (not just the microprocessor board [1]) but also the servo board has a couple of PROMs and the personality board has as state machine built round 82114s (PROMs with built-in latches). Something to investigate sometime. [1] The control processor is an 8085, the firmware is mostly in 8355/8755 ROM+I/O chips. I think there is a conventional 2K ROM there too, There seems to be a total of 10K of firmware which seems like quite a lot. I doubt DEC ever published the firmware source, but it can't hurt to ask here :-) Oh yes, the PSU. The R80 printset shows the original version. Mine has a later PSU. The RA81 printset contains most of the schematics, for some odd reason the motor control relay PCB [2] is missed out, my guess is it was a simple error. The RA82 printset contains the complete PSU schematics. [2] The spindle motor in all these drives is a capacitor start induction motor. The capactor is in the top chassis with the logic PCBs. Unlike most such motors, the starting winding is not controlled by a speed operated centrifugal switch. Rather, there are 2 relays in the PSU, one for the run winding, one for the starting winding. They are controlled by the microprocessor, which checks the spindle speed via the optoswitch on the bottom of the HDA The RM80 is an R80 with an external massbus interface. AFAIK all RM80 drive spares, docs, etc apply to the R80. The RA80 is also very similar (different personality (interface) PCB, different firmware, but otherwise much the same). The RA81 and RA82 are electroncially quite different, but mechanically similar and it's worth reading their manuals with that in mind. The RA82 printset (I think) has some information on how the HDA was assembled. It appears that the spindle/disks are assembled into the lower metal case, the upper case is fitted and bolted down, then the positioner/heads slides in from the front (I assume with some tool to keep the heads apart). Then the head and positioner cables plug into a PCB on HDA front cover which fits in place and is clipped down. Of course all this has to be done in a clean room. But for some odd reason the schematics of that HDA head PCB are in the printset, for all they are pretty much useless for repair (custom ICs that you can't get to without dismantling the HDA in a clean room). -tony From wdonzelli at gmail.com Fri Jun 12 16:46:36 2015 From: wdonzelli at gmail.com (William Donzelli) Date: Fri, 12 Jun 2015 17:46:36 -0400 Subject: PDP-8/S In-Reply-To: <20150612134357.217DD18C0CA@mercury.lcs.mit.edu> References: <20150612134357.217DD18C0CA@mercury.lcs.mit.edu> Message-ID: > > If somebody were to try to make a "complete" list, it would make sense > > to provide variable levels of anonymity > > ... > > Prob'ly some people would be more willing to discuss what they have IFF > > they aren't opening themselves to theft risk, and/or a deluge of "I'd > > like to buy". > > Let me second that.

I think going with the 1660 is the better deal ... you do make a good point about schematics and repairability ... and hack-ability ... there are plenty of very exotic looking components ... especially on the acquisition cards ... on the newer machines that I'm sure are basically impossible to repair. I just try to manage that risk by keeping as many spare cards on hand as I can get for the 16500 series, and I've always got the 1662 standing by in case something happened to it ... honestly, when you can get a HP 166x for $100, unless you enjoy the sport of troubleshooting and repair in and of itself (and I do so sometimes myself) is it really worth sinking much time and effort into repairing a 1630 series, or a K100? I just want folks to be aware ... people might not necessarily realize, what their money will get them; I'd hate for someone to shell out for a 1630 when they could have gotten a 166x or 167x for the same price...

I noticed that in addition to the 31-second beep symptom that the terminal was also no longer saving my settings after a power cycle and so I figured the back-up battery was dead (I'd replaced it when I got it a few years back) so I figured I'd try replacing it again and see if had anything to do with the prolonged beep. Answer: Tes. The terminal now initializes normally with a nice short series of beeps. So, if anyone in the future sees similar symptoms, it could very well be the battery and the HP is deciding to tell you in an incredibly annoying and uninformative manner... - Josh On 6/7/15 1:52 PM, Josh Dersch wrote: > Hi all -- > > The lovely HP 3082A terminal I've been using with my PDP-11/73 has > started exhibiting odd/annoying behavior today.

I understand and agree (very much!) with your concern, but I don't think it's going to be an issue: for every $1M Apple I, there are a zillion other old computers you can't even give away.

This is wrong. There are a fair amount of Enigmas in collections that are not on a registry. Also, serial numbers are easy to forge and deface on vintage military electronics. When five or six figure values are concerned, a forger starts to get very good in his craft. Anyway, registries are not as big of a deterrent as one might think. Serious thieves, fencers, and unethical buyers generally do not care. -- Will From jnc at mercury.lcs.mit.edu Sat Jun 13 10:20:19 2015 From: jnc at mercury.lcs.mit.edu (Noel Chiappa) Date: Sat, 13 Jun 2015 11:20:19 -0400 (EDT) Subject: Coating on older DEC slides Message-ID: <20150613152019.69F4818C0B0@mercury.lcs.mit.edu> So I have a bunch of older DEC slides (for BA11 boxes, RK05's, etc) which are rusty. No problem, I have a sand-blaster, but.... what's the grey coating on them, and how do I reproduce it once I have them clean? I saw Corey Cohen's really wonderful presentation at VCFE about restoring old computers, and afterwards I asked him if he knew anything, and he said that (from my description - alas, I didn't think to show him one in the display area) it sounded like a powder coat thing, and that people who do brake calipers can do power coating. However, when I went to my car guy for pointers to local people who do brake calipers, he looked at the coating, scraped at it a bit with a knife, and said it didn't look like powder coat to him. (Although maybe this is a very old powder coat, and he's only used to the newer stuff.) He reckoned it was just grey paint {visualize dubious-looking Noel - it sure doesn't look like paint to me}. So, what _is_ that grey coating - and, more important, how (if at all) can it be reproduced these days?

I understand Tandy wanted to move away from the "TRS-80? name, hence the "Tandy 6000?, but it was really just a slightly enhanced TRS-80 Model 16B. Now, the ?16? name makes sense?16-bit OS support on the added cards. Of course. at the same time, Tandy had the x86 series with the 1000, 2000. etc. Giving the machine a name of 6000 makes it seem like it was supposed to be their top-of-the-line machine.

It was my impression that the "Tandy" branded line consisted mostly of equipment targeted squarely at the business community, who might have been less receptive to the moniker "Radio Shack". However, there was duplication between the "Radio Shack" and "Tandy" products. Tandy did have their own B&M retail outlets. That being said, my Model 16 bears the "Radio Shack" label. --Chuck From rodsmallwood52 at btinternet.com Sat Jun 13 14:52:04 2015 From: rodsmallwood52 at btinternet.com (Rod Smallwood) Date: Sat, 13 Jun 2015 20:52:04 +0100 Subject: Coating on older DEC slides In-Reply-To: <20150613154503.GA18351@dbit.dbit.com> References: <20150613152019.69F4818C0B0@mercury.lcs.mit.edu> <20150613154503.GA18351@dbit.dbit.com> Message-ID: <557C89E4.2060101@btinternet.com> It might be cadmium On 13/06/2015 16:45, John Wilson wrote: > On Sat, Jun 13, 2015 at 11:20:19AM -0400, Noel Chiappa wrote: >> So, what _is_ that grey coating - and, more important, how (if at all) can it >> be reproduced these days? > Wild guess: some kind of oxide?

I think going with the Of course. And I my comments are my personal opinion too. I think that giving such opinions, backed up with facts (as you are certainly doing) is worthwhile. Please don't think I am flaming you, or that I don't think your views are worth considering. This is classiccmp, a list for old computers. And even I (classic machine lover than I am) will happily agree that a modern PC has a much higher CPU performance than any of our classics. We've just had a thread on the VAX 11/730. This is probably the slowest VAX ever, just about anything running an emulator will beat it. This does not mean (IMHO) that the 11/730 is not worth restoring. There are many reasons for liking classic computers, CPU speed is generally not important. Similarly there are many (IMHO good) reasons for liking classic test gear. Provided the limitations are known, and it is used sensibly, it will still give good results. A 100Msample/sec logic analyser from the 1980s is still a 100Msample/sec logic analyser. It may not be fast enough for some modern work, it probably is fast enough for working on classic computers. In the end I think it comes down to knowing the various instruments, the pros and cons of each and making a choice, What you choose is ultimately up to you. > 1660 is the better deal ... you do make a good point about schematics and > repairability ... and hack-ability ... there are plenty of very exotic > looking components ... especially on the acquisition cards ... on the newer > machines that I'm sure are basically impossible to repair. Be warned that even the HP1630 has custom ICs on the acquisition boards. AFAIK the Gould K100D is all standard ECL parts. For me, the reasons for choosing the K100D would be the documentation and standard ICs. And the fact that it is easy to make custom probes for it. The reason for choosing the HP1630 are the mostly standard ICs, the documentation, and the HPIL interface. -tony From rodsmallwood52 at btinternet.com Sat Jun 13 14:58:08 2015 From: rodsmallwood52 at btinternet.com (Rod Smallwood) Date: Sat, 13 Jun 2015 20:58:08 +0100 Subject: Collectors pay big money for old tech In-Reply-To: <20150613115749.9C71818C0A9@mercury.lcs.mit.edu> References: <20150613115749.9C71818C0A9@mercury.lcs.mit.edu> Message-ID: <557C8B50.6090601@btinternet.com> After all this time unless the configuration in the box is the same as the label on the back then all you have is the serial number of the box and I dont think empty system boxes are worth much.

Since the WD 179x controller > could not write a truly exact model 1 format single density disk (did not The data address markers on the directory cylinder of a M1 TRS-DOS disk are one of the odd ones that only a 1771 can write. IIRC if you do a double density upgrade to an M1, you end up with both 1771 and 179x disk controller chips so that you can still write original M1 TRS-DOS disks. The M3 only has the 179x controller. There were many other changes between the M1 and M3 hardware. Most noticeable is that many I/O devices were memory mapped on the M1 (in the area between the ROMs and RAM), but were mapped as I/O ports on the M3. One odditiy was the Centronics printer port. Memory mapped on the M1 (write to the address to send a character to the printer, read it to check printer status) and I/O mapped on the M3. But because so much software directly read that address to check a printer was present and ready, the M3 (and M4) allows a read from the same memory address to check the printer status. But AFAIK you have to use the I/O address to output a character. There were enough changes between the M1 and M3 that in general M1 disk software will not run on an M3 and vice versa. > support certain data address marks), there were some kludges and changes > in TRS-DOS, so there were minor glitches in the "upgrade path". > Radio Shack eventually cut a deal to market L-DOS as TRS-DOS 6. > ("And Randy Cook is now finally collecting royalties!") TRS-DOS 6 (LDOS 6, LS-DOS 6) was a M4 operating system. However, IIRC the hard disk OS for the M1 and M3 was LDOS 5.1.x and was sold by Radio Shack. > Soon, the model 4 was made available - same basic machine with 80x24 video > (V 51x16), green screen, a few missing keys provided, and ability to > remap the ROM from the memory map. Finally, CP/M was available without The M1 and M3 were limited to 48K RAM (64K memory map space, 12K or 14K for ROM, the rest for video, keyboard, I/O devices). The M4 could take 128K RAM, there was bank switching logic to map RAM, ROM, video, etc into the 64K CPU memory map. You could have the plain 64K RAM that CP/M liked. Note that a M4 can almost perfectly emulate an M3, and will boot M3 OSes, run M3 software, etc If you do this you lose the M4 enhancements (you have 48K RAM, ROM at location 0, 64*16 video etc). But it lets you use the older software if you want to. The M4 uses the same disk system (and RS232 interface board) as the M3. Disk machines have a single-bit sound output device, quite why this wasn't fitted to cassette-based machines is beyond me. > Model 4P was luggable version, vaguely resembling early Compaq. One incompatibilty here, the 4P has no cassette port.

I've got a few pounds of dry moly disulfide here and it's nasty stuff--gets everywhere and is a black-silver in color. About as bad as graphite. Gun people sometimes tumble their shells in it. Don't ask how I know... If this is a small job and you need a solid coating, have a look at some of the moly-teflon rattle-can gun coatings from Brownell. You spray them on, then bake them. The finish is very tough and pretty much foolproof. I've got a few HP slides from a storage array and I'll swear they're just plain old electroplated zinc. --Chuck From nf6x at nf6x.net Sat Jun 13 17:51:31 2015 From: nf6x at nf6x.net (Mark J.

Yet another way is to use BACKUP /NOASSIST - this should avoid issueing OPCOM messages and prompt the issuer of the BACKUP command directly when tapes are to be changed and so on. The standard way of doing backups on VMS is to submit a BACKUP command in a batch job. The operator would normally be logged in interactively and would respond to the OPCOM messages from the batch job and deal with tape mounts. This requires a suitable batch queue to be set up and started. Regards, Peter Coghlan.

I bet that's how I used to run backups as a student computer operator in the late 1980s. But I probably had no understanding of the DCL script I presumably ran. -- Mark J.

If the connector on the DELUA board is a normal Berg-type header (and I think it is) then maybe you could use a piece of (twist-n-flat?) ribbon cable to make an extension that could be routed through the cable pan arrangement and then connected to the original DELUA cable back in the rack cabinet. -tony From nf6x at nf6x.net Sun Jun 14 12:25:07 2015 From: nf6x at nf6x.net (Mark J.

That might be a good approach. The DELUA end of the cable has a Berg connector, and the other end has the typical 15-pin D-sub AUI connector with a slide latch. I'll look up the cable wiring to see if signals that would best be twisted pairs are conveniently placed on adjacent odd/even pins, such that twisted pair ribbon cable would work well electrically. Or maybe I can use the round cable that I already have, with P-shaped cable clamps screwed down using the screws at one end of the flat cable clamps. There may not be enough clearance in the tray for that. -- Mark J.

There may not be enough clearance in the tray for that. What happened to the original cable and distribution panel? As a warning - the original distribution panel have a fuse for the 15-pin Dsub, to avoid excessive power use on the connector. If you go directly from the board to a transciever, you might run the risk of damaging the DELUA itself if something goes wrong. Put another way. The design is to have an internal cable from the DELUA to a distribution panel at the back of the machine. There you have the 15 pin AUI connector, which have a fuse. You then had an external AUI cable from there to your transciever, which traditionally sat on a thick coax. Of course, later on, you started having thin ethernet. Still AUI cable and transciever, though. Eventually twisted pair showed up. But you had transcievers for that as well. And if you have room behind the machine, you could connect the thin ethernet or twisted pair transscievers directly to the distribution panel connector, so no actual external cable.

The panel has a circuit breaker, a 15 pin D connector on the outer side for the transceiver, and another 15 pin D connector on the inner side for the internal cable between the DELUA card and the distribution panel. The back of the 730 chassis does not have an open slot for the Ethernet transceiver, as all of the other slots are already occupied. A bracket for the Ethernet bulkhead panel is screwed to one of the rack's rear panel brackets. Whoever routed the internal round cable before I got the machine did a less than perfect job, so it kept getting snagged when sliding the 730 chassis in and out. The cable jacket has many nicks, but they do not appear to penetrate the conductor jackets. I've just tried reinstalling it, and things aren't moving smoothly yet. I don't think that round cable behaves properly in the flat cable flex area, so next I will see if I can find a clean path between the card cage and a different area of the chassis where I can route it along the gantry that supports the power inlet cable. The round cable just doesn't route as cleanly as the original bundle of flat cables, so I'll need to fiddle and cuss until I get it working well. Once I manage to route the internal cable, I'll plug in a DEC AUI cable to the bulkhead panel, and a DEC 10baseT transceiver, and see if I can get networking up. The first time I started playing with VAXen as a student, there was generally a long AUI cable running to a vampire tap on thick yellow coax. Sometimes the coax was routed through the building, and occasionally there would be a vampire tap down in the stem tunnels with an AUI cable extending into a subbasement. I've never installed a vampire tap myself. Then a couple years later at a different university, most of the easily accessible wiring was thin coax, and 10baseT was still newfangled. > On Jun 14, 2015, at 11:27, Johnny Billquist wrote: > >> On 2015-06-14 19:25, Mark J.

The DELUA end of the cable has a Berg connec$ (Please try to avoid paragraph-length lines.) I once had a machine in a case it wasn't designed for, leading me to want to extend a DA-15 AUI connector. I experimented with plain untwisted, unshielded, un-ground-planed 15-pin ribbon cable between the machine and a UTP transceiver. I found that a foot or two of ribbon cable made no visible difference. As an experiment, I then tried about thirty feet of ribbon cable and got ludicrously high error rates. On calculating, I find that, at 10Mb, bits are about 65 feet long (at that sort of frequency, signals in copper travel by skin effect at roughly 2/3 c), and, since it's Manchester encoded, the underlying data rate is twice that, meaning a transition potentially every 30ish feet. A cable two to three feet long is short enough for everything to settle in plenty of time even if the impedances are mismatched, but one thirty feet long is about the size of the underlying bits and it's entirely understandable that it would cause trouble. So, if you can hang a transceiver off the back of the machine with little-to-no drop cable length, you can probably get away with a few feet of pretty much anything, but if you want to run any significant length of drop cable, you may well need to treat it as a transmission line and worry about characterstic impedance and shielding and such. But it's worth experimenting with anyway; it's possible the cable you have has the right impedance or some such! /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mouse at rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B From bqt at update.uu.se Sun Jun 14 14:49:24 2015 From: bqt at update.uu.se (Johnny Billquist) Date: Sun, 14 Jun 2015 21:49:24 +0200 Subject: First VAX-11/730 VMS Boot!

Ok. Good. > The back of the 730 chassis does not have an open slot for the Ethernet transceiver, as all of the other slots are already occupied. A bracket for the Ethernet bulkhead panel is screwed to one of the rack's rear panel brackets. Whoever routed the internal round cable before I got the machine did a less than perfect job, so it kept getting snagged when sliding the 730 chassis in and out. The cable jacket has many nicks, but they do not appear to penetrate the conductor jackets. Ah. Yes, an extra mounting bracket was not that uncommon.

I don't think that round cable behaves properly in the flat cable flex area, so next I will see if I can find a clean path between the card cage and a different area of the chassis where I can route it along the gantry that supports the power inlet cable. The round cable just doesn't route as cleanly as the original bundle of flat cables, so I'll need to fiddle and cuss until I get it working well. While the round cable sometimes can cause different problems, I can't say I've ever had any actual problems routing it in the end. > Once I manage to route the internal cable, I'll plug in a DEC AUI cable to the bulkhead panel, and a DEC 10baseT transceiver, and see if I can get networking up.

Although with > the null modem or without I get nothing. I wouldn't assume anything with serial ports, especially vintage ones. Look into getting a "traffic light" that displays state on LEDs either in red or red/green (depending on how old/expensive the traffic light - I have both kinds). The "easy" way to sniff out a connection with one is to plug the traffic light into only one side of your connection and see which lines are active, then unplug that and plug it only into the other side and see which lines are active. If you have your null-modem/no-null-modem swaps right, the active lines will be complementary on each side. If, say, RxD is active on both, you'll need a null modem. When you have it right, you should see lights blink when one side or the other is trying to talk. Choosing a baud rate slower than 9600 bps makes it easier to see. Also, some hardware needs hardware flow control present and working. Newer stuff is fast enough that mostly, people just do 3-wire serial (RxD, TxD, and GND), but stuff from the 1970s is expecting CTS and RTS and all that to do the proper things. Sometimes, you can just wire up the computer side to always have CTS active and things will work fine since the computer/terminal side can keep up and doesn't have to throttle one character at a time. Frequently, this requirement can be enabled/disabled with jumpers or software settings on the computer side, but if not, you might need a custom console cable. This is part of the joy of serial comms. If you aren't used to debugging line speeds and parity bits and null-padding chars and hardware handshake lines, it can get very frustrating when you try to connect two devices and they won't talk. By the mid-90s, when most serial comms were relegated to various types of modems, many of the earlier limitations were no longer important, but the further back you go, the more parameters you had to get right before traffic flowed. -ethan From fozztexx at fozztexx.com Sun Jun 14 16:09:43 2015 From: fozztexx at fozztexx.com (Chris Osborn) Date: Sun, 14 Jun 2015 14:09:43 -0700 Subject: Altos ACS 8000-15A In-Reply-To: References: Message-ID: On Jun 14, 2015, at 2:00 PM, Ethan Dicks wrote: > I wouldn't assume anything with serial ports, especially vintage ones. > Look into getting a "traffic light" that displays state on LEDs Back in college in the HP lab we had these really nice RS232 breakout boxes with jumper pins and LEDs that were in a sort of pink case.

The manual says that it uses DTR for flow control and doesn?t mention DSR, so I suspect it?s a one-way thing like the HP terminals and only tells the other end to stop and will send whenever it wants without checking if it?s ok. -- Follow me on twitter: @FozzTexx Check out my blog: http://insentricity.com From cclist at sydex.com Sun Jun 14 16:18:59 2015 From: cclist at sydex.com (Chuck Guzis) Date: Sun, 14 Jun 2015 14:18:59 -0700 Subject: Altos ACS 8000-15A In-Reply-To: References: Message-ID: <557DEFC3.7080705@sydex.com> On 06/14/2015 02:09 PM, Chris Osborn wrote: > Back in college in the HP lab we had these really nice RS232 breakout > boxes with jumper pins and LEDs that were in a sort of pink case. > While I used them all the time I can no longer remember who made them > or find anything close.

King) Date: Sun, 14 Jun 2015 21:47:20 -0700 Subject: Opening up a TeleVideo TPC-1 Message-ID: Hi folks, I was in an antique store today, mostly to humor my wife, and much to her dismay spotted a fairly early luggable: it said TeleVideo on the face and, looking closer, it was a TPC-1 with the keyboard, the carrying bag, the documentation AND a metric butt-ton of floppies. Once I get everything sorted I'll let the list know what software I have, so if you need something maybe I can help.... ...and maybe you can help me. I want to open up the TPC and check power supplies, etc. - OK, I'll come clean. I plugged it in, watched carefully for magic smoke and, seeing none, put a 'working disk' in the drive. I got an endless string of '.' but no boot. I tried a couple of other disks labeled and, after a couple, I no longer had a display. So no surprise, I really need to open it up and probably replace a bunch of PS capacitors. I have no idea how to get this box open! There's nothing in the documentation, and I found one online reference that suggested TeleVideo kept this information close to the chest because they didn't want any Tom, Dick or Ian opening up their machines. Now if I poke and prod long enough I'll probably get there, but with the collective knowledge on this list I figure there has to be SOME one who worked on these back In The Day, who just knows this off the top of his/her head. So... anyone? Thanks -- Ian -- Ian S.

There's nothing in the No real idea either, but obvious things (to me!) to check are the feet (either screwed on through the case into the internal chassis, or screws under stick-on feet) and the handle, which on luggables is likely to be fixed to the chassis too. Are there any visible screws at all? Sometimes you have to take off a thin-ish plastic bezel or something to reveal the real case screws. -tony From jason at smbfc.net Mon Jun 15 01:04:02 2015 From: jason at smbfc.net (Jason Howe) Date: Sun, 14 Jun 2015 23:04:02 -0700 Subject: Any DOS Gamers out there??

The drive had one fixed and one removable platter, the removable being a 12-sector 5440-style cartridge. The drive may have been a CDC 9427H, or something similar. The controller was two Multibus boards, a 3000 bit-slice based channel board, and a drive interface board. (Similar organization to the two-board floppy controllers.) I am mostly looking for the schematics and programming information, though if anyone has an actual controller board (or even just the channel board), a dump of the microcode would be useful. The documentation I'm looking for might or might not be contained in the "Model 740 Hard Disk Subsystem Operation and Checkout" manual, order number 9800943A. Note that this is *entirely* different than the iMDX 750 winchester disk subsystem. The 740 was supported by plain ISIS-II 4.x, while the iMDS 750 used a variant of the iSBC 215 controller, and required a special ISIS-II(W). Thanks!

I believe sending a BREAK on ttya is equivalent to the Stop-A from the graphics head but it's been a while ... there might also be an equivalent for Stop-D. I would suspect it's more likely to be just in a different baud rate, than to have the number of data bits, parity, etc modified ... but you never know ... just where I'd begin ... If you have an old serial protocol analyzer sitting around, it should be able to figure it out pretty quickly. Have you tried taking a peek through the service manual? It might have some other suggestions. The Sparc 10 was a great little machine in its day ... rock solid ... it made an excellent, compact, light-duty server; I used to have a ton of them!

After some debugging, it works nicely. I am sorry, but I find that obscene!. To use more components than the rest of the machine (probably) just for the baud rate clock is ridiculous. IMHO if you are going to modify a vintage machine, particularly one as rare as a PDP12, you should use the components that were available at the time. It's not as if a programmable buad rate generator is hard to make from TTL either. In fact given the Arduino thing needed 'some debugging' it might well have taken less time to do it in hardware. -tony From tmfdmike at gmail.com Sun Jun 14 02:05:56 2015 From: tmfdmike at gmail.com (Mike Ross) Date: Sun, 14 Jun 2015 19:05:56 +1200 Subject: SS10 console settings Message-ID: Folks, I'm trying to resurrect a couple of Sparcstation 10 systems.

This is the part that pushes the print drum against the ribbon and paper to print. These are newly molded parts that have not been available for decades. Works very nicely. The ripple on the power supplies is still going lower as we put more run time on the system. The power supplies are now within spec. Warren wrote a better memory checkerboard program that shows the bits that were being picked up or dropped in the MQ register. We tried adjusting the STROBE FIELD 0 delay about +/- 100nS, but there was no setting that resulted in completely working memory. Changing the delay did change the location and number of bits that were picked up or dropped. Since the failing addresses were all above 1000 we tried replacing the G221 modules in slots C07 and C08. There was no change. We suspect that we have a problem in the inhibit circuits. Warren made an Arduino based programmable baud rate generator that works for both serial ports. After some debugging, it works nicely. The donor dropped off the work table that goes in front of the PDP-12.

I looked at the pictures and googled the brand and model and it didn?t seem to be a very common computer and there were no bids on the item so I put in a fairly low bid. I ended up winning! :-) The seller asked if it would be ok to bring the item to me the next time he was in my area. I figured that was fine since I was concerned that since it has a large 8? hard drive in it that it would be more likely to be damaged in shipping. I actually didn?t even need to wait very long! Friday he set out to drive across 2 states and dropped off the computer at my front door on Saturday morning. Talk about excellent service! I buy lots of untested items on eBay and usually they work just fine. But luck hasn?t held for me this time and so far the Altos doesn?t work. I can hear the drives spin up and all the voltages from the DC power supply are perfect. But nothing spits out on the Console 1 RS232 port. From what I understand the serial ports are wired DTE (which seems odd since you use it with terminals) and so I?m using a null modem adapter. Although with the null modem or without I get nothing. Anyways, I posted an album with lots of pictures here: http://imgur.com/a/9X8Gh Yay another project for me to fix! :-) -- Follow me on twitter: @FozzTexx Check out my blog: http://insentricity.com From tmfdmike at gmail.com Sun Jun 14 16:22:24 2015 From: tmfdmike at gmail.com (Mike Ross) Date: Mon, 15 Jun 2015 09:22:24 +1200 Subject: SS10 console settings In-Reply-To: References: Message-ID: Sorry, didn't notice I'd replied to an email rather than the list. >From last night: OK I'll have to get to the bottom of this at some point, but it seems it WAS the cable!

I had a nasty version of that years ago, the system would work with a VT100 (at lower baud rates), but not at all with my Tandy M100 laptop. 2) Too much stray capacitance. Given a sensible output impedance on the driver (and there is a specification for this), this will round off the pulses, make narrow pulses too small, and so on. This is the more likely cause I think.

The RS232 specification allows for 2 serial channels on the DB25 connector. Most machines only use the primary channel. and Sun were sensible enough to wire their '2 ports on one connector' so that port A uses the primary channel pins and port B uses the 'back channel'. This means that if you plug a normal, minimally-wired serial cable in (say an adapter to a PC DE9 port) you connect to port A.

We're talking about putting in a rather complex computer to generate a baud rate. Are people really that handicapped when it comes to building hardware nowadays? Are people aware how easy baud generators are? We're essentially talking about a clock, which can be found as a component (various oscillators), and then dividing it. There used to be chips around which did that part, and I would expect it to not be that hard to find some if you looked today. Many UARTs even comes with a clock divider built in. And that is it. When I build various Z80 systems, I usually had a Z80 CTC included, which I used for generating the baud rates.

Are people really that handicapped when it comes to > building hardware nowadays? Speaking as someone who didn't do that, but might well have - it's not a question of "handicapped"; it's a question of convenience, ease of use, and suchlike. Yes, I know how to build a BRG in hardware. I've even done it, more or less. But if I want something fast, and I have a small SOC handy, I may well use it: it's a lot easier to change the generated frequency in more-or-less arbitrary ways (ie, other than just picking a different tap off a divider chain), and it's quite possible the SOC is at readier hand than the oscillator and divider. Of course, if it's going to be there for more than the short term, I probably will replace it once I've settled on a frequency. But initially? Sure, I'll go with the "complex" way, for convenience and flexibility. I'm also likely to fire up a calculator program on a desktop computer to add two five-digit numbers rather than reaching for pencil and paper or a dedicated calculator. Even though I'm hardly incapable of using either of the latter. When the more powerful tool is handy and its use carries no sigificant downside, I see nothing wrong with overkill. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mouse at rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B From jnc at mercury.lcs.mit.edu Mon Jun 15 08:11:35 2015 From: jnc at mercury.lcs.mit.edu (Noel Chiappa) Date: Mon, 15 Jun 2015 09:11:35 -0400 (EDT) Subject: Front Panel Tech Note 2 Message-ID: <20150615131135.5A09718C0B7@mercury.lcs.mit.edu> > From: Pontus Pihlgren >> Seeing the one with the one with the missing toggle switches reminds >> me that I have an enquiry out re getting some made. > I believe many would appreciate that.

They've been 3D printed with the sintered nylon process, dyed and polished with good results thanks to the efforts of Vince Slyngstad. I'm not sure if Vince also did the model of it or had some help, but I'm quite satisfied with mine mechanically speaking, though the yellow is a little light for my 8/E.

If you want over kill try this:- https://www.youtube.com/watch?v=ALXax3Gydl8 and FPGA implementation of the Baby or SSEM which had 32x32 bits of RAM. The implementation uses around 1% of the Spartan 3E 1200K gates, and that includes the logic to generate the VGA which is around 50% of the circuit. I expect to get it on a 100K gate chip but that?s still over-kill. I am also aware how HARD baud rate generator chips are. Firstly you need to know the multiplier, and then you need a crystal that can easily be divided. I looked on E-Bay UK and the cheapest dedicated baud rate generator was 10x the price of a Arduino Nano. Then I would need a crystal and the other bits to make the generator. I would expect the chip count on a dedicated baud rate generator board to exceed that of the Nano. Of course it is not original, but an authentic board would only use SSI TTL and where would one find that easily. I personally think it is an appropriate cludge that allows de-bugging to continue and gives you time to work out what the best long term solution would be.

I tried spraying a white Nova 3 handle that I had printed with the same process with Krylon Fusion yellow. That gave a slightly less "bright" yellow with a good satin finish, and the handle hasn't melted down into a smelly mess, as I gather can happen with some paints. (And is also why I did this with the Nova 3 prototype handle that didn't fit well anyway.) It was actually even quicker and easier than sealing the yellow or orange porous sintered nylon with urethane floor polish. > Maybe some of the 11/20 colors would turn out better. I don't like the Shapeways dye colors for the -11 colors, though I suppose if you did the whole panel it would look OK. (The "pink" is sort of the right magenta, but much too bright.) I'd probably just print them in white (slightly cheaper too), then look for a suitable spray paint. Since the surface is so porous, I don't think there'll be the problems with the paint failing to bond that a non-porous plastic would have. Designs can be found here: http://www.so-much-stuff.com/pdp8/cad/3d.php though the commentary is slightly out of date, as usual.

Agreed. I really love the modern microcontrollers like the Arduino and tiny embedded computers with GPIO like the Raspberry Pi or Galileo because they make it so incredibly easy to turn a hardware problem into a software problem. And writing software is super easy, even if you?re not an expert. You can just keep trying another solution over and over and all you have to do is push a few keys on your keyboard. -- Follow me on twitter: @FozzTexx Check out my blog: http://insentricity.com From rodsmallwood52 at btinternet.com Mon Jun 15 09:31:55 2015 From: rodsmallwood52 at btinternet.com (Rod Smallwood) Date: Mon, 15 Jun 2015 15:31:55 +0100 Subject: Front Panel Tech Note 2 In-Reply-To: <20150615131135.5A09718C0B7@mercury.lcs.mit.edu> References: <20150615131135.5A09718C0B7@mercury.lcs.mit.edu> Message-ID: <557EE1DB.8030201@btinternet.com> I can tell you what they were called internally at DEC.

There were ones listed at least as low as $37, but I picked one that had all of the accessories, cables and disks that I would have pieced together otherwise. It has been handy for debugging communications between my VAX-11/730 and tu58em.

Without losing anything else in the already-full rack, I'd need to route that cable between two racks. It's already tricky to roll the cabinets back into place without rolling over the existing round snakes between the cabinets, and I figure that wide ribbon cables would be more cumbersome (or is the BC11A round?).

An expansion without a reapeater would work just fine electrically. I'm curious about whether some sort of repeater exists that uses a thin, round cable for an application where it's desirable to be able to move the expansion around easily. And also where it's cheap and easy to replace the cable after rolling a rack cabinet over it one time too many! :) -- Mark J.

Just as TTL needs to be stockpiled, I think we should be in a habit of archiving virtual machines containing development software installed in a compatible operating system, so the software can still hopefully be used long after the original machines are obsolete. Much like we often use SIMH now for maintenance tasks to help bring up old machines that no longer live in an ecosystem of similar machines. -- Mark J.

First, initialize all the tapes you might need using the same label as you will use when you run backup. Second, run your backups as a batch job and then VMS does not expect you to reply to requests for new tapes, he just expects the tape to appear.

In-Reply-To: References: , Message-ID: > > I'm not specifically familiar with the 11/730, but what's wrong with just cabling up an expansion box "the old > fashioned way" using BC11A cable? Nothing electtically... The problem is that the 11/730 mouting box (BA11-Z??) is a bit odd. The boards go in from the left. Cables end up going downwards (either straight down or over the top of the card cage, then down between the backplane and PSU). Then into a removeable tray on the bottom of the mouting box, round a flexible plastic sheet and to another tray fixed in the rack. The idea is to make the cables route nicely when yout slide the box in and out (something you have to do on the 11/730 to change the microcode tape or get to the main circuit breaker). I am not sure how a BC11A cable would like being folded back and forth like that. The official way was, I think a board in the Unibus out slot of the 11/730 that had 3 40 pin Berg headers on it. This took 3 normal 40 way ribbon cables which went round the cable routing thing and to a similar board in the Unibus in slot of the expansion box. I think there were even bulkhead panels to route the cables to another rack cabinet. I have the boards and cabling somewhere... My 11/730, which is a 'to be started soon' project has 4M of RAM and thus 2 spare hex height slots. One contains a DMF32, the other a TSU05 tape controller. I have a half-rack to put it all in. Obviously I am putting the CPU and R80 drive in that rack, the question is what else. I think an RL02 is pointless (the Integrated disk controller in the CPU of an 11/730 will talk to up to 4 drives. One can be a R80, the others are RL02s). The obvious thing is a TS05 (Cipher F880) tape drive, I have one but with a wrecked door so it needs repairs. I wonder if a Unibus expansion box would be more use though. Incidentally : It appears the DECSA (ethernet comms server) PSU is the same PSU as that in the 11/730 with the memory PSU board left out. The schematics are in the 11/730 printset, they are not in the DECSA printset. Similarly the LA100 printset doesn't include the PSU schematic, the LA210 one does, and it's the same unit again. Totally useless coincidence that I noticed while doing a cryptic crossword : 'ethernet' is an anagram of 'three ten', and the original ethernet speeds were three and then ten megabits/second. -tony From cclist at sydex.com Mon Jun 15 12:17:24 2015 From: cclist at sydex.com (Chuck Guzis) Date: Mon, 15 Jun 2015 10:17:24 -0700 Subject: Fix for duplicate (and triplicate) messages on cctalk?

That would work. Still, it would be nice to find a front panel mechanical drawing and see what they are called on the BoM. (I tried to find one for the 11/20 front panel, and although I found the tech manual for it, I couldn't the print set for the front panel.)

I'm a bit more pragmatic. Whatever it takes to get something running, I'll do it. For me, that's the entire point of having the old stuff around. Otherwise, a non-working box is scarcely better than any other piece of antique e-waste. If there's an accurate emulation available on modern hardware, I'll use that rather than play with some old, cranky piece of iron. Others may certainly have different opinions. --Chuck From robert.jarratt at ntlworld.com Mon Jun 15 12:26:07 2015 From: robert.jarratt at ntlworld.com (Robert Jarratt) Date: Mon, 15 Jun 2015 18:26:07 +0100 Subject: VAX 11/730 In-Reply-To: References: <557EF004.1060507@e-bbes.com> Message-ID: <012a01d0a790$5d88f3d0$189adb70$@ntlworld.com> And I would like to find one in the UK.... > -----Original Message----- > From: cctalk [mailto:cctalk-bounces at classiccmp.org] On Behalf Of Mark J. > Blair > Sent: 15 June 2015 16:34 > To: General Discussion: On-Topic and Off-Topic Posts > Subject: Re: VAX 11/730 > > If you can find one, I'll be happy to help out with tape images and so forth for > your bringup! > > > > > On Jun 15, 2015, at 08:32, emanuel stiebler wrote: > > > > As usual, a long shot, but anybody in the list like to get rid of one? > > Preferably Colorado ;-) From bfranchuk at jetnet.ab.ca Mon Jun 15 12:28:50 2015 From: bfranchuk at jetnet.ab.ca (ben) Date: Mon, 15 Jun 2015 11:28:50 -0600 Subject: FPGA tricks - Re: using new technology on old machines.

In addition to HALT, you also have BOOT and BFLG. I can't remember which is what right now, but one of them is what R5 gets set to in this case, and you need it to be 0.

The idea is to make the cables route nicely when yout slide the box in and out (something > you have to do on the 11/730 to change the microcode tape or get to the main circuit breaker). That's a much better description of the 730's mechanical peculiarities than I came up with. I was more concerned with cable management between the two racks, since I have them in a tiny room where I need to roll them around to get access to the back (it's literally a tiny bedroom in a manufactured home... basically a doublewide trailer that's been fastened to a foundation after having the axles and drawbar cut off!). It's already tricky to roll the racks back into place without running over the power cables, tape drive cables, serial lines and power controller cable. But managing the cables in the cable tray area is another thing that needs to be done right. > > I am not sure how a BC11A cable would like being folded back and forth like that.

I think there were even bulkhead panels to route the cables to another rack cabinet. Three narrower cables sound like they would be easier to manage than one wide one. Based on the hardware user's guide that I have (and which I do plan to scan and share), I gather that UNIBUS expansion cabinets would generally be used in a configuration that's in a larger rack and has both TU58 slots on the front panel. I haven't seen one of those in person before. My system is the configuration that's in one or two short racks. The main one is completely filled by the RL02, VAX-11/730 and R80 drives, from top to bottom. The other rack contains the optional TU80, with an unused bay below it. I haven't measured the size of that unused bay yet, but it looks like it may be tall enough for a UNIBUS chassis. Maybe I could adapt one of my empty PDP-11/44 chassis boxes for use as an expansion chassis? Or another possible use for that slot could be for my Kennedy 9610 tape drive. The TU80 looks like it probably has a Pertec interface, so I should be able to add the Kennedy drive to the chain to get more BPI options in the system. Now that I have a computer with a Pertec interface running, buying/building a Pertec adapter for my Mac or Sun doesn't seem so important. Assuming I can bring up networking on the VAX that is, and that I can figure out how to do block-level stuff under VMS. -- Mark J.

I am probably working on to much simultaneously. But this machine is 100 km away so it is just now and then I do something with it. Like this weekend. The real console tape tape drive is in questionable status although not tested. I tried to use the mockup I did based on the TU58 emulator by Bela T?r?k. But I wasn't successful (I had it working previously on an LSI-11 so I am not sure what is wrong - I guess that I told that it was working perfectly previously - well I was wrong). Then I compiled your fork of tu58em on github. And it worked perfect. I didn't need to use the special vax mode that you have implemented though. Ma?be it is required only by 11/730? The bad thing with the 11/750 is that is has so many socketed TTL gate array chips. Sockets are bad. And gate arrays are bad. In that sense I think the 11/730 is better since it is AFAIK based on mostly standard off the shelf chips. In a way I am happy that is indeed running the BOOT58 program and several of the diagnostics but it sure would be very interesting to know why this Translation Buffer / Cache diagnostic fails. Were there any listings available for the VAX diagnostics? The micro diagnostics run in the RDM module is pretty well described in a document on bitsavers. There are no details though. But for the native VAX-11 diagnostics I can not find anything. Next step would be to create a SCSI disk with a VMS installation on it. Hopefully I manage to do that using SimH. I don't have any nice TU80 to go with the machine so it is not possible to do an install from tape. I do have a lead on a TU81 PLUS, but it is some 900 km away currently... /Mattis From nf6x at nf6x.net Mon Jun 15 13:12:23 2015 From: nf6x at nf6x.net (Mark J.

Temporarily and reversibly, of course, and I'd hope to replace them with proper stuff when possible. But to bring up an old computer system right now, I'll kludge in what I have available to get it running.

The 730 appears to have one 20ms timeout in a critical part of the drive initialization routine (which is entered repeatedly in normal operation, not just at power-up), and stock tu58em has a delay in that spot that is problematic. Maybe the 750 console code either lacks the timeout check or has a longer timeout period? > The bad thing with the 11/750 is that is has so many socketed TTL gate > array chips. Sockets are bad.

There are no custom ICs on the IDT (disk controller), FP730 (floating point) or memory boards AFAIK. What is on Unibus peripheral cards depends on what you have :-) The rest of the CPU (and IDT, FP) is some TTL, an 8085, standand RAMs (SRAM and DRAM), 2901 bit slice ALUs, PROMs (in general the bit-dumps are in the printset, the only ones not there are the 4K firmware for the 8085 console processor) and lots of PALs, again the logic equations for these are in the printset. Oh yes, the TU58 controller board has a PROM on it that you don't get a dump of but it is a standard TU58 controller so I assume somebody has dumped it. So I am happy to try to keep an 11/730 running The R80 disk drive has again, lots of TTL and analogue parts, an 8085 system using the Intel 8155 RAM/IO and 8355 ROM/IO chips (alas no dumps of the firmware in the prints ), a couple of other sets of PROMs (no dumps :-() and a few custom head switching and servo preamp ICs _inside the HDA_ where you can't really replace them. My view is that the R80 electronics is repairable (and I must make a dump of the ROMs) but that the HDA is likely to be a problem area anyway. There are some good 11/730 manuals on bitsavers. As well as the printsets (worth reading with a hackish eye) there are technical descriptions of the CPU, Disk controller and floating point board. They refer to a similar manual for the PSU which is, unfortuantely, not on bitsavers. Said manuals explain a lot of things that are not totally obvious from the printset. Things that I would love to see (but I suspect were never published) are a source of the 8085 firmware in the 11/730 and a source of the standard microcode for said machine. Oh, and a source for the R80 firmware. -tony From ard at p850ug1.demon.co.uk Mon Jun 15 13:41:20 2015 From: ard at p850ug1.demon.co.uk (tony duell) Date: Mon, 15 Jun 2015 18:41:20 +0000 Subject: Serial UNIBUS Repeater?

But managing the cables in the cable tray area is another thing that needs to be done right. My 11/730 was totally decabled to get it to me. I think I have most of the original cables, and most of the metalwork. I've read the descriptions in the hardware manual on bitsavers and I am not looking forward to routing all those cables... Oh well.... It's a nice idea for a system that is not going to change, but adding or removing cables for a particular peripheral option is going to be painful. I suspect routing all the cables between the trays on a bench and then mounting the bits in the rack is OK. But since the rack part of the tray has to be fitted before the CPU box sildes, removing it every time you want to add or remove a cable is not practical and fiddling a cable in or out is going to be non-trivial. So not really a good idea for the likes of me who is always changing things. That's why I am thinking of adding a BA11K or something on top. > Based on the hardware user's guide that I have (and which I do plan to scan and share), I gather that UNIBUS > expansion cabinets would generally be used in a configuration that's in a larger rack and has both TU58 slots > on the front panel.

Why not do it properly first time? What is the rush in bringing up a classic computer? And for a test, use the TTL pulse generator you have on your bench. Or even an NE555 astable (yes, with a decent capacitor it is stable enough for a baud rate generator, I've used it). Heck, I've worked on machines that used a 2 transistor astable multivibrator for the baud clock. Surely you have 2N3904s in the spares box?

You make it sound like I am suggesting using lookahead carry generators, parallel multipliers, Excess 3 to 1-of-n decoders and the like (all of which exist(ed) in TTL). No, I am suggesting using some very common counter and gate ICs. How are you going to fix a TTL-based machine like your 11/730 without spares and without knowing what the ICs do? > present itself.

It is cheating :-) More seriously, tools are one thing. And had it been suggested that as a quick fix you took the TTL output from a sig-gen or took the output and clipped it to TTL with a transistor buffer then that would IMHO be reasonable (even if said sig-gen contained many times the number of components of the rest of the machine). But to make a custom solution that is over-complicated IMHO is the wrong way to do it. You might well inject your HP sig-gen into the mixer (first detector) stage of your WW2 radio to get it going if the local oscillator had failed, or if you didn't have the right crystal, or whatever. But I hope you wouldn't replace the valve (tube) based local oscillator in such a set with a digital synthesiser as a permanent 'repair' -tony From nf6x at nf6x.net Mon Jun 15 13:58:42 2015 From: nf6x at nf6x.net (Mark J.

Can't anyone read a schematic and think???? The exact same argument could be made for somebody using an NE555 instead of discrete transistors to blink an LED, or discrete transistors instead of vacuum tubes to blink a neon glow lamp. For that matter, I might call somebody a slacker for blinking an LED with an NE555 instead of an LM3909. But LM3909s are no longer manufacturer or stocked. An NE555 only costs $.50 vs. about $1 for an ATtiny, but these days, folks under the age of 40 are a lot more likely to have an ATtiny (or more likely, an ATmega on an Arduino board) sitting on their desktop. -- Mark J.

Oh well.... Sorry to hear that it's been decabled. Take your time to route those cables through the bottom pan properly, and based on my experience so far, I do not recommend trying to route anything but flat cables through the pan area. Route anything round up over the top and along the folding support arm (what I've been calling a "gantry", but not necessarily correctly). For anything temporary, might as well leave the cabinet slid out and let the cable dangle. The 730 is nicely made for sliding in and out easily, but really not optimized for frequent hardware configuration changes. > It's a nice idea for a system that is not going to change, but adding or removing cables for a particular > peripheral option is going to be painful. Yup, you're exactly right about that. > That's why I am thinking of adding a BA11K or something on top. That makes sense to me, particularly if you will not be constrained by the original rack configuration like I am. The 730 has limited UNIBUS slots anyway, so might as well use an expansion rack for anything you might change frequently. -- Mark J.

I believe you had a father that got you of to a good start and perhaps you even took a few classes. My father was great but knew very little about electronics.

I'm not at your level yet.. but perhaps in a few years I'll be a tenth of the way there :) It might please you to hear that the Teensy I'm talking about is in a socket on a perfboard together with a handfull of 74165 and 74374 which I've wirewrapped in proper wirewrapping sockets. It will become a USB interface for my 11/70 front panel. The Teensy was the simplest/cheapest way to get a usb interface with lots of I/O pins.

What is the rush in bringing up a classic computer? Sorry for yet another reply, but I didn't think of this until just now: When I was working on getting tu58em functioning with my 730's console code a couple weeks ago, a few folks recommended that I build an Arduino-based emulator that has been known to work well. But I didn't, because I didn't have that particular kind of Arduino board on hand, and I wanted to get it working that weekend instead of the next one. And I did. :P > 'Full stock of TTL parts' ???

The same way I got my HMMWV running back in 2000. I had quite a bit of parts and tools on hand already from my previous work on my M543A2, and plenty of manuals to study. Some things I fixed with what I already had on hand. And when I found that the injection pump needed rebuilding, I took out the pump and brought it to a local Stanadyne shop. And I ordered a replacement radius rod end after I determined I needed it, not before. I had a lot of 1/4"-20 grade 8 hardware in my junk box already for misc. mechanical repairs, but I still had to order some more for sizes I hadn't encountered before. Back on the 730, I don't have most of the parts you mentioned on hand already because I've only gotten into retrocomputing within the last 2 years, and I've spend most of the last 30 years keeping with the times. Hint: I haven't designed a through-hole board at work since the early 1990s, and I didn't use perfboard the last time I built a GPS receiver the size of my pinky fingernail (not an exaggeration). ;) -- Mark J.

I must admit that I used to scorn those durned kids using Arduinos to do the job of a 555. But then I pulled my head out of my ass and realized that times change, nowadays a microcontroller is as cheap and common component as a 555 was when I was a snotty kid, and the new-fangled "maker" movement with its Arduinos and serial-controlled addressable LEDs and conductive thread is keeping younger people designing things and making them instead of just being dumb consumers.

As long as you don't damage the firebox installing your heater, what's the big deal? Making first steam is going to be a gradual and careful process anyway, and using a different heat source fora while to eliminate a variable might just make sense. Or maybe it doesn't. All I know about steam was learned in that thermodynamics course back in college, so I don't know best practices for boilers, other than "I am not qualified to weld one". > (yes, feel free to lecture me how big that heater would have to be...)

Should I criticize you for not having SAE grade 8 > hardware on hand, or Bristo wrenches I think Tony's point was that someone who's into vintage computers ought to have a stock of suitable parts for them. So unless he's into older guns, or cars, were he not to have things like SAE 8 hardware around, that would be understandable - he doesn't do them. Having said that, _I_ don't have 2N3904s nor NE555s around either! I do have a modest number of parts (e.g. 4164's, 40-ping Berg shells, .250 tab hardware, etc, etc) - a large enough collection that I just had to re-organize and add more parts holders (although that was mostly because I went berserk at the local Radio Shack in the 80% off sale). But it takes a long time to build up a really comprehensive collection of parts. It's funny, I was thinking of this exact topic last night - wondering if I could find someone who's selling off a large cabinet full of mixed spares! (I was thinking of the experience of one list member, who lucked into such.) I could certainly use it!

It actually might be essentially the same machine. From what I can tell the 15A originally shipped with two 8? floppy drives.

I got into the arcade & pinball hobby over a decade ago, would travel to people home?s and fix their machines, and really got into the retro computing thing about 3 years ago. I don?t have a huge collection of parts either, just what I bought to fix something or make something. One nice thing is there is a lot of crossover of technology with both hobbies, so I?m often surprised to find I happen to already have something on hand. What sucks is ordering things that I actually *did* have because I didn?t know. I?ve slowly started to be a little more organized but things are still scattered all over in different boxes. I decided to standardize on those 24 compartment and 18 compartment storage containers from Harbor Freight since they fit quite well in the wooden crates I?ve been making. http://imgur.com/a/UsFn3 -- Follow me on twitter: @FozzTexx Check out my blog: http://insentricity.com From fozztexx at fozztexx.com Mon Jun 15 16:52:58 2015 From: fozztexx at fozztexx.com (Chris Osborn) Date: Mon, 15 Jun 2015 14:52:58 -0700 Subject: Altos ACS 8000-15A In-Reply-To: <770620F7-16BA-4612-8478-BF91DC9F9A16@platinum.net> References: <5B7C014C-83A7-43EF-8D5B-FD0959E9BBE1@platinum.net> <770620F7-16BA-4612-8478-BF91DC9F9A16@platinum.net> Message-ID: On Jun 15, 2015, at 2:36 PM, Ian McLaughlin wrote: > Does your reader have any other ?brands? of 2716 you could try?

I had that same mental hangup when thinking about how I might design an SD card based TU58 emulator in the same form factor as a TU58 cartridge (still on my to-do list, by the way). How was I going to implement the user interface? It's not like there's much room for an LCD or buttons on the edge of a TU58 cartridge. Then it finally hit me: SD cards are cheaper than TU58 cartridges ever were. So why not just use the first 256k, ignore the rest of the card, and swap cards exactly the way one would swap TU58 cartridges, with one image on each card? Yeah, 99% of the card is "wasted", but they're presently cheap and plentiful enough to ignore that. Ok, I might actually have the emulator read a file from a DOS filesystem rather than using the first 256k of raw blocks. But it'll probably just be a fixed filename with no controls to select a different one, and the expectation that an entire (cheap, plentiful) SD card will be devoted to each tape image. At least this way, other things can also be on the card, so it doesn't need to be wasted if not needed. Your friend should understand that the larger card that he would be "wasting" probably has less silicon in it than the older one with less capacity. The cheapest card that is reliable, fast enough and large enough for his task is the best one to get, even if it's much larger than he needs. Just one of the weird parts of the Moore's Law curve! Hmm, this reminds me that back in the day, floppy disks were expensive. We have it easy with cheap and plentiful SD cards nowadays. But maybe my perspective is different as an employed adult rather than a teenager with limited funds? Anyway, SD cards seem to be cheap enough to be nearly disposable nowadays. -- Mark J.

One wonders why some manufacturer didn't realize there was money to be made in smaller cards (now less competition, but still enough demand to drive the prices up) and keep making them.

Yes, that'll likely be true once they have been in the hobby for a while. But for somebody who has gotten into it recently, and otherwise hasn't had reason to touch a DIP packaged part since the early 1990s (even while being a full-time electrical engineer and full-time electronics/etc. hobbyist), it can't be taken for granted that they have a parts drawer full of misc. 74LS parts. I have a vast junkbox, and I regularly order electronic components both professionally and for my hobby... and I still don't have a lot of TTL parts on hand. -- Mark J.

Because the chip fab equipment that was used to make the dies in the spaller parts has probably already been retired in favor for equipment suitable for smaller process geometries, and there's no point in making dies with storage capacity smaller than what fits in the minimum die size dictated by the pad ring necessary for the I/O. There actually is a lower limit to memory capacity, beyond which the cost cannot be reduced and the die cannot be shrunk. We call such chips "pad limited", as in the I/O pads dictate a minimum die size, and the die will cost almost exactly the same (save for minor yield variations) whether the middle is filled with gates or not. I don't think that the hangups of a very few people justify ignoring the economics of semiconductor manufacturing. -- Mark J.

I managed to get a copy of ISE10.1 downloaded, installed and running without phoning, ringing or otherwise jumping through hoops. That supports the Spartan 2 which has been obsolete for some time.. If you want to play with some Spartan 2 chips contact me off-line. Altera has the old version of Quartus for download on their site. I had to take advantage of this to get a version that would compile for my Cyclone I. :) Anyone with older chips might want to grab the appropriate versions while they are still there... --Toby > >> You want to make a mod 5 years down the road, sorry we do not support >> that model any more.

I'm curious because my VAX-11/730 backplane is full, and it would be nice to be able to experiment with additional hardware without needing to pull out one of the existing boards, i.e., adding a TK50 interface without removing the DEUNA, adding a SCSI card to boot from a scsi2sd without pulling the integrated drive controller, etc. There's a blank spot in the TU80 cabinet that looks like it may be tall enough for an expansion chassis, but the thought of adding more big ribbon cables to the belly plate area and then routing them between racks doesn't appeal to me. Running something like a CAT5 cable between the two racks would be a lot easier. Another application would be for placing a small remote UNIBUS backplane on the test bench for easy access, and cabling it to a VAX or PDP-11 elsewhere in the room. > > This should be quite possible with modern hardware, but I'm curious about whether something similar has been done before. > > -- > Mark J.

Interesting! Thanks for sharing! I could probably make one "cheaper", but I couldn't make one "cheap". :) Another approach would be to build a BC11A-equivalent cable using multiple narrower ribbon cables (as previously mentioned in this thread), and use the round-jacketed-shielded ribbon cable. The stuff isn't cheap, though, and a couple of round-jacketed 40-conductor cables probably aren't any more flexible than the Pertec tape drive cables I already have snaking about between the racks. -- Mark J.

Perhaps like me you will be left feeling that we were so much better at this stuff 40 years ago.

For that matter, I might call Err, to blink a neon glow lamp you use _one_ resistor and _one_ capacitor and make use of the difference between striking and maintaining voltages. But that is not the point. The original design for this M452 baud rate clock is an RC oscillator. One that can run at any reasonable frequency. When restoring a machine you should keep as much of the original design as possible. If you want to do a reversable change you should still change as little as possible. Since it appears you can change the buad rate just by changing a couple of passive components that's what IMHO you should do. -tony From ard at p850ug1.demon.co.uk Mon Jun 15 23:20:32 2015 From: ard at p850ug1.demon.co.uk (tony duell) Date: Tue, 16 Jun 2015 04:20:32 +0000 Subject: Serial UNIBUS Repeater?

Mine did start out as the 'packaged' system in the half-rack, and I intend to keep it in that cabinet.

My father was a chemist. He knew enough electronics to teach me things like ohm's law, but certainly not digital electronics. And I have never done any classes in electronics. I learnt by : 1) Reading every darn book I could find on electronics from the 1920s onwards 2) Experimenting. Soldering up circuits and finding out why they didn't work. Some of the better educational kits like the Philips EE series helped in my younger days, but alas you won't find those now. 3)Getting a minicomputer and investigating it.

This module is hardly complicatated. OK, it is not obvious what some of the waveforms are (which is a good reason to put that board on the bench -- it will run on its own -- and probe it with a 'scope. Being an oscillator, all the waveforms are repetitive so _any_ 'scope will do), but it is farily clear that it is an RC oscillator and that the time constant of a particular RC network is going to have an effect on the output frequency. So you change the capacitor and probe with the 'scope again. And so on. -tony /P From ard at p850ug1.demon.co.uk Mon Jun 15 23:40:00 2015 From: ard at p850ug1.demon.co.uk (tony duell) Date: Tue, 16 Jun 2015 04:40:00 +0000 Subject: using new technology on old machines In-Reply-To: <20150615211937.50B0F18C09B@mercury.lcs.mit.edu> References: <20150615211937.50B0F18C09B@mercury.lcs.mit.edu> Message-ID: > > I could replace an M1 Carbine trigger spring on the spot, or a HMMWV > > taillamp housing ...

Exactly. I don't do firearms at all (we have various IMHO ridiculous laws in the UK, but I do not want to start that debate) and while I have repaired many cars in the past, I don't drive and don't, therefore, own a car of any type. But if you are going to repair/restore something then IMHO it makes a lot of sense to have common spares around. It's not like I am suggesting you should keep stocks of obscure HP custom microprocessors, or even things like 2901 bit-slice chips. But common TTL parts, transistors, etc are used in many machines, and if you are going to restore the real hardware you are (a) going to need them and (b) are going to need to now how they work so you can trace faults. > Having said that, _I_ don't have 2N3904s nor NE555s around either!

One method that works for me is that if you are buying a fairly cheap part, buy 10 of them and put the rest in stock.

In mine, an RL02 drive is the third unit of the rack containing the CPU cabinet, and the TU80 tape drive is too tall for that slot (though one of the later front-loaders would probably fit). If you don't need an RL02 drive, then i think the hole it would leave behind is just the right size for an expansion chassis. Hmm, if it's the same rack that originally had the RL02 in it, then there should be no top panel, as the top-mounted RL02 was meant to be opened without sliding it out. With an expansion chassis in its place, you should be able to get full top access to the expansion chassis without sliding anything in or out. That seems like it would be super awesome since you want easy access for swapping cards. And no need to run a BC11A cable between racks, either. I've played with the idea of making a top cover for my main rack that rests on the cabinet sides, straddling the RL02. If I unscrew the shipping bracket at the back of the RL02 then I could slide it out for pack changes, and leave other stuff like a terminal sitting on top. I usually seem to have stuff sitting on top of the RL02 and/or TU80 anyway, and then I need to shuffle the stuff around whenever I need to open one or the other. Ok, that's enough enthusiastic agreement for now. Off to the other thread for some more enthusiastic disagreement! :) -- Mark J.

The RPi is neat for what it is, but I have a mental hangup on openness, which the Beaglebone Black has more of (i.e., I think I could buy the main chip on it from DigiKey, unlike the Broadcom chip on the RPi. Not that I'm eager to route my own SDRAM bus... that's actually kind of hard, particularly with the open-source PCB tools I use for home projects). The BeagleBone also has lots more delicious IOs. > This is one of my main dislikes with USB. It is so complicated that you > have to use a microcontroller.

I liked moving away from having to figure out which way the danged plugs were wired at both ends for any given pair of devices.

People have made transistors at home, even made their own semiconductors (copper oxide) to do this, but they are not good ones.

Agreed! But you generally tend to accumulate those spares *after* you have been involved in that particular area for a while. Coming into it from scratch, you might not even know which parts you're most likely to need.

Right. So coming in from scratch, you might buy a tube of 74LS00 instead of just the one that you need to fix one board, and so on for many other common parts. > One method that works for me is that if you are buying a fairly cheap part, buy > 10 of them and put the rest in stock.

For example, the first time I had a Rifa paper-dielectric EMI filtering cap go incandescent on me (happened to be in a Tandy Model 12), I figured out the three or four kinds of much better poly film EMI filtering caps I'd need to replace them on sight in the Astec supplies that Tandy stuck in everything, and I bought lots of extras. But I don't have a single 2N3904 in my junk box, because I don't think I've had to replace one in the last 30 years, just based on the kinds of things I've been working on. So it's not my go-to part. Now, 10k resistors and 0.1uF ceramic caps... those things I use a lot. :) -- Mark J. Blair, NF6X http://www.nf6x.net/ From nf6x at nf6x.net Tue Jun 16 00:06:59 2015 From: nf6x at nf6x.net (Mark J.

This is a 18 bit cpu with the concept, byte access of memory needs true 18 bit addressing and 16 bits is bit small for general 1970's data. Think of it as a something like a 9 bit 6800 cpu. Ben.

Well, that was obvious. But it raises an interesting point, today you can cram a whole computer in the footprint of the simplest DIP carrier. For the same price point and same reliablity. Is it then overkill if you choose to use thousands of those transistor over using just 10 ? Similar to Mark's example of using just the first bytes of an SD card with gigabytes of storage. > This is one of my main dislikes with USB.

I completely agree, I detest USB for various reasons. However consider this: As I said, I have used the Teensy to interface an old 11/70 front panel with simh. One possibility I've considered is to let the Teensy present itself as USB mass storage when first attached to a PC. On this mass storage I would put a special version of simh and 11/70 system images. When this version of simh is run, it will instruct the Teensy to present itself as the front panel interface instead. So, I can bring my 11/70 front panel to any friend with a suitable computer and show him/her the ropes :) Admittedly, the Teensy doesn't have enough storage for this, but it shows the flexibilty of USB coupled with a microcontroller. /P From mattislind at gmail.com Tue Jun 16 02:59:27 2015 From: mattislind at gmail.com (Mattis Lind) Date: Tue, 16 Jun 2015 09:59:27 +0200 Subject: Reviving a VAX-11/750 In-Reply-To: <76C96A4A-9A44-45EE-83F2-CE321B16E2CE@nf6x.net> References: <297BBD27-571E-470D-9FE9-BE6588851517@nf6x.net> <76C96A4A-9A44-45EE-83F2-CE321B16E2CE@nf6x.net> Message-ID: In my efforts to understand the problem with the Cache/TB Diagnostics I tried to run it under 11/750 simulator in SimH.

You will get no argument from me that the _same design_ is more reliable the more 'LSI' it is -- that is a processor as a single chip is more reliable than the same design in TTL which in turn is more reliable than the same design in discrete transistors. But when you compare different designs, I am not conviced. My experience is that I have had to replace many more LSI ICs than TTL and many more TTL chips than transistors (power transistors, choppers, line output transistors excpeted!). I am not at all convinced that a microcontroller is as reliable as a 555 timer. After all, microcontrollers presumably store their firmware in some kind of flash memory which is going to suffer from bit-rot. A 555 doesn't. > Similar to Mark's example of using just the first bytes of an SD card > with gigabytes of storage. Again, I wonder if the data retention time decreases as the number of bits per device increases. Intuitively it should.

To me, classic computing means rather more than just the hardware. It also covers the design and construction methods, technology and so on. And there seems to be precious little of that in a modern microcontroller acting as a clock oscillator. I find it odd that people want to have a lights-and-switches panel, but are prepared to totally adulterate the hardware of the machine that drives it.

The VAX-11/730 System Installation Guide (EK-SI730-IN-003) has information about how to load the catch pan. Given all the 90 degree and 45 degree folds, it's the sort of thing you only want to do to a fresh cable once. There might also be a specific 11/730-Z detailed installation manual. I have a memory of one but don't know the part number. My memories of those days (we had two 11/730s) is that if you don't do it the way they did, either things won't reach (or be on the wrong side to fit into bulkhead connectors) or you'll have to redo it. https://archive.org/details/bitsavers_decvax730E83_4699164 > Exactly.

We did have that. It was nearly essential. We had the CPU, memory, and the default (as shipped) peripherals. Everything else went into our BA-11K FWIW, we only had the RB80/RL02 version. Tape was a TU80 with the controller in the BA-11K. Our COMBOARDs also went in the BA-11K, but that was also for our convenience of swapping out our own product for testing and firmware swaps, etc. -ethan From nf6x at nf6x.net Tue Jun 16 09:18:49 2015 From: nf6x at nf6x.net (Mark J.

After all that is what the machine was designed to use. I'll consider using my real TU58 drive instead of an emulator when I find a working TU58 cartridge. So far, that is foreign to my experience. :( I've cleaned up my drive and replaced the capstan rubber, and I think my drive is probably just fine. The problem is the media, which in my opinion was a poor mechanical design when new. I also thoroughly distrust the similar mechanism of the larger QIC tapes. -- Mark J.

The larger that region, the less often you re-write the same cells, thereby extending the life of all the cells. Chris On Monday (06/15/2015 at 03:06PM -0700), Mark J.

How was I going to implement the user interface? It's not like there's much room for an LCD or buttons on the edge of a TU58 cartridge. Then it finally hit me: SD cards are cheaper than TU58 cartridges ever were. So why not just use the first 256k, ignore the rest of the card, and swap cards exactly the way one would swap TU58 cartridges, with one image on each card? Yeah, 99% of the card is "wasted", but they're presently cheap and plentiful enough to ignore that. > > Ok, I might actually have the emulator read a file from a DOS filesystem rather than using the first 256k of raw blocks. But it'll probably just be a fixed filename with no controls to select a different one, and the expectation that an entire (cheap, plentiful) SD card will be devoted to each tape image. At least this way, other things can also be on the card, so it doesn't need to be wasted if not needed. > > Your friend should understand that the larger card that he would be "wasting" probably has less silicon in it than the older one with less capacity.

Or more than 10 if it > is something really common. I suspect a lot of us do that - that's why I have tubes of 4164's, etc, for instance. It makes a lot of sense, because it's trivial to implement - it's just as much work to order 10 of something, as 1. But that model isn't really the best, because a lot of the time one winds up needing something one doesn't already have. Which is why it's better to lay in a diversified stock up front. E.g. in wood screws (I do a lot of work in wood, mostly furniture), I have a fairly comprehensive collection; from #6 through #12, all the available lengths (not the very longest ones, though), counter-sunk and round-headed, with both slot and Phillips drive. But doing so in IC's - oi vey! Just in TTL alone, there are dozens of common parts (hundreds, if you count the more obscure ones), and then you get into the whole 74, 74S, 74LS, 74ALS, 74L, 74H, 74F, yadda-yadda. Of course, most of the variants one would never need, but one can't get by with just, e.g. LS; e.g. if I ever get my wish and wind up with a PDP-11/45, that's mostly S, IIRC. I wish there was some _easy_ way to lay in a stock of the most common TTL IC's - e.g. some kind of kit one could buy - but alas, I don't know of any. (Hence my dream of finding and acquiring someone else's collection! :-) Suggestions for the source of such a good diversified 'starter kit' welcome...

When I was working for a GPS startup, I used mini-B on everything I designed with USB (always devices, never hosts, and no need for USB OTG). Then we got bought by a cell phone company and now everything's a godawful mix of mini-B and micro-B, with OTG thrown in there, too. Grrr! I'm going straight to hell because I recently participated in a customer design where they wanted to change the USB function on a device we designed for them from host mode to device mode but they didn't want to change the connector on the box. So, now you have to use a Type A to Type A cable to connect this box to your computer. That is just really, really messed up and I honestly tried to make it right but it was like pushing a rope.

By the standards of that era, any modern computer (probably including the one in your microwave oven) is *large*. For example, the THE OS memory footprint is about 16k words (48k bytes), and that includes not just what we think of as a kernel but also all the device drivers and a bunch of language support library code.

Blair) Date: Tue, 16 Jun 2015 08:25:29 -0700 Subject: On the Emulation of TU58s Message-ID: As long as we're talking philosophy, what do y'all think about emulating the TU58 drive, vs. emulating the TU58 *tape*? I cannot properly express my opinion of that tape cartridge design even if I violate list rules about use of profanity. But the drive itself isn't all that bad, aside from not having enough motors to manipulate a well-designed tape cartridge mechanism. Emulating the whole tape drive is pretty easy since it helpfully interfaces over a plain old asynchronous serial port. But replacing the whole drive with an emulator, or worse yet tethering its computer to a modern computer, leaves a bit of an empty feeling if one likes their vintage machines to be original. There's something missing when you don't hear the drive whirring, and the system boot completes within a modern attention span. But what about emulating the tape cartridge, instead? Imagine a gizmo in the form factor of a TU58 cartridge, containing a wheel for the capstan roller to engage, but connected to an encoder instead of the ******* ************ ***** ** **** belt drive of an original cartridge? Where the tape would normally be exposed, there is instead a magnetic head which rests against the tape drive head like in one of those gizmos for injecting line level audio into an audio cassette drive. It might need an external power source, but for the sake of argument, let's pretend that a suitable rechargeable battery can be embedded. Maybe it has an SD card slot on the rear, or maybe it looks just like a real TU58 cartridge when inserted, and you swap the whole thing to change tapes (this is open for discussion). Would this be more or less acceptable in terms of keeping the system as close to original as possible, vs. unplugging the original drive and plugging in a drive emulator? No, I'm not going to build the thing. I'll just build my TU58 drive emulator to fit in the cartridge slot but plug into the computer in place of the original drive, with the cables snaked through the original drive mechanism. And I'll feel a little bit dirty, but the thing will work reliably and will be easy to implement. I'm just curious about the philosophical implications of my silly cartridge emulator idea. -- Mark J.

But the drive itself isn't all that bad, aside from not having enough motors to manipulate a > well-designed tape cartridge mechanism. The tape cartridge (along with QIC cartridges, etc) is an interesting design. Of course the general problem is to run the tape at constant linear speed past the head while winding it off one reel onto the other. In general there have been 3 solutions to this. One is to drive the tape itself using a capstan and maybe a pinch roller. Then have the takeup spool driven too fast with a slipping clutch in-line. And a weak brake on the supply spool. This of course is what was done in audio recorders (reel to reel and cassette), Video recorders (ditto), etc. Another is to simply drive the takeup spool but to measure the speed of the outside of the tape wound on it. thus keeping a constant tape speed. I had forgotten this one until I realised that's how the Cipher F880 works. Or maybe to run the tape round a rotating guide that has a tacho disk on it. I've not seen that used, but I bet it was somewhere. The last is to drive the outside of the tape wound on the spools. Of course this keeps constant tape speed. Mechanically it is by far the simplest. All you need is one motor driving a belt that is tensioned against the outside of the tape spools. This is how the TU58, etc, work. The problem is due to the physical properties of the tape and belt, which leads to tape wear and damage and a short life. There are at least 2 types of TU58 cartridge (DEC called them 'metal base' and 'plastic base' I think. Is one any better than the other? Incidentally, given the fact that a constant motor speed -> constant tape speed, it should be possible to make a device to put the timing track on a blank tape for the TU58. Has anyone done that? > But what about emulating the tape cartridge, instead? Imagine a gizmo in the form factor of a TU58 cartridge, > containing a wheel for the capstan roller to engage, but connected to an encoder instead of the ******* > ************ ***** ** **** belt drive of an original cartridge? Where the tape would normally be exposed, there is Now that I want to see! Even a module containing coupling head and encoder disk that slots into a TU58 drive and which links to an external box of electronics containing the SD card, etc, would be interesting. You would, of course, not know which track it was reading, so you would have to output 2 blocks, one on each track, at once. And how would you detect it was writing? Look for an extra signal at the coupling head or something? -tony From bfranchuk at jetnet.ab.ca Tue Jun 16 11:14:06 2015 From: bfranchuk at jetnet.ab.ca (ben) Date: Tue, 16 Jun 2015 10:14:06 -0600 Subject: O/S design & implementation - was Re: FPGA tricks - Re: using new technology on old machines In-Reply-To: <54ADA80E-66F3-4011-96D0-1AF989739068@comcast.net> References: <557DD8F6.1000809@dds.nl> <557EA05C.5020702@update.uu.se> <06e101d0a770$1fb9f240$5f2dd6c0$@gmail.com> <557EEA76.8000501@telegraphics.com.au> <557EFAC7.3000809@jetnet.ab.ca> <557F54D2.6070507@telegraphics.com.au> <557FC6EE.3030303@jetnet.ab.ca> <54ADA80E-66F3-4011-96D0-1AF989739068@comcast.net> Message-ID: <55804B4E.3020102@jetnet.ab.ca> On 6/16/2015 8:56 AM, Paul Koning wrote: > >> On Jun 16, 2015, at 2:49 AM, ben wrote: >> >>> ... >>> >> Since the computer I designed is a *small* computer, 8 & 16 bit >> operating systems is what I am looking at for ideas.

And yet another (possibly the most common one on computers) is to have a small drive wheel that pulls the tape at constant speed across the heads, and then have some other construction that drives the tape reels depending on tape tension or length. Think vacuum columns or spring loaded arms. And then we have drives like the TU80/TU81 which do not seem to fit into any of the mentioned categories. I'm not entirely sure how they work, but I think they are similar to the DECtape in this sense.

The Revox G36 (736) and Brennell Mk 5 among them (I happen to have both). Actually, the Philips V2000 video recorders (home machines, not professional but quite the best of the home systems) did that. They had a pair of DC motors to directly drive the 2 spools along with the capstan and head drum motors. No slipping clutches. Back tension was provided not by a light brake on the supply spool but by a suitable current through the supply spool motor in those machines. -tony From nf6x at nf6x.net Tue Jun 16 12:48:57 2015 From: nf6x at nf6x.net (Mark J.

I can think of several ways it could work.... 1) There is a tacho on an arm that rests against the takeup spool (as in the Cipher F880). The control system drives the spools to keep that speed constant. 2) Similar, but the tacho is a rotating tape guide that the tape goes round 3) It assumes the takeup spool is intially empty. It then drives forwards, and measures the speed of the supply spool. From that, you can work out the diameter of the supply spool, and thus I guess the amount of tape. You can then (a) determine where you are on the tape by the relative speed of the 2 spools, this gives you the amount of tape on the takeup spool and thus how fast you need to turn that to get the right speed. One of my VHS video recorders does something similar to work out how much recording space is left on the cassette. -tony From ard at p850ug1.demon.co.uk Tue Jun 16 12:54:40 2015 From: ard at p850ug1.demon.co.uk (tony duell) Date: Tue, 16 Jun 2015 17:54:40 +0000 Subject: On the Emulation of TU58s In-Reply-To: References: , Message-ID: > That seems to me like it would be the trickiest part.

Instead, the motors (on both sides) are driven by the uptake available. When there is too little, the motors run to give out some more tape. When there is too much, the motors run to pick up the excess. So, motors can actually run in both directions, as needed. They are actually controlled by a pretty dumb closed loop system. The actual tape movement as such, is all done by the small wheel next to the head, which just runs the tape past the head. >> And then we have drives like the TU80/TU81 which do not seem to fit into >> any of the mentioned categories.

There can definitely be a tacho on the motor, but since you do not know how much tape is on the reel, this will actually not tell you the tape speed. But there is no tacho on the tape itself, unless my memory fails me. > 2) Similar, but the tacho is a rotating tape guide that the tape goes round See above. > 3) It assumes the takeup spool is intially empty.

That would be very hard, as you do not know the thickness of the tape, nor the diameter of the tape reel center. I've been wondering if there is some sensor of tape tension/pressure at the heads, and this will allow the drive to figure out how much faster/slower the reels must run, relative to each other, in order to keep the tape tensioned. Then you can figure out tape speed across the heads (if you care) by just observing flux changes. > One of my VHS video recorders does something similar to work out how much recording space is > left on the cassette.

Each column have about 8 pressure switches. When 4 have low pressure, and 4 have atmospheric pressure, the drive is happey, and the reels are resting. When the point of underpressure/pressure moves down, the reel on that side starts moving to pick up more tape, thus moving the point back towards neutral. When the point moves up, the reel starts moving to give out more tape, to move the point back down again. The more switches triggered in either direction, the faster the reel will move. The movement of the tape across the head is controlled by a third motor, which have a smaller wheel on it. The tape lies against this reel, but it's all done by friction. This wheel pretty much runs the tape across the head at constant speed, and this movement of the tape will also cause the points in the two columns to move, which in turn will trigger action as described in the previous section. Not sure where the counter-rotating capstans would fit into this either... And there is only negative pressure, and it is applied to the tape at all time.

In this case we're talking about overpressure to act as a cushion, and not underpressure to act as a takeup/buffer mechanism.

So I decided to read up on the TU81 operation, and it does work by creating an overpressure to act as a bearing before and after the head. The overpressure is also used to detect tape tension so that a constant tension can be maintained. The supply reel is controlled by the air pressure sensors, so that tension is maintained, while the pickup reel is directly controlling the speed. Both reels have tachos as well. There is no capstan, but constant linear speed can be maintained by the fact that the takeup reel is of a known size, and you have the tachos, and you essentially can estimate good enough how much tape is on the takeup reel. (Lots of computations in here... :-) ) Johnny From ard at p850ug1.demon.co.uk Tue Jun 16 14:20:59 2015 From: ard at p850ug1.demon.co.uk (tony duell) Date: Tue, 16 Jun 2015 19:20:59 +0000 Subject: On the Emulation of TU58s In-Reply-To: <55806813.7090704@update.uu.se> References: , <55805D6E.8030400@update.uu.se> , <55806813.7090704@update.uu.se> Message-ID: > > > >> And yet another (possibly the most common one on computers) is to have a > >> small drive wheel that pulls the tape at constant speed across the > >> heads, and then have some other construction that drives the tape reels > >> depending on tape tension or length.

Some do. I remember using IBM tape drives on a 360 Model 44 that were amazingly badly designed. Part 1: two capstans spinning all the time, in opposite directions. Solenoid-activated pinch rollers would press the tape against the capstan to set it moving. The same solenoid-activated pinch roller moved in the opposite direction would press the tape against a non-moving ?capstan" to stop it. Part 2: vacuum columns ? no surprise there. But why on earth would anyone build a vacuum column that has the oxide side of the tape facing OUTward, rubbing the oxide against the column side walls? Amazingly enough, those drives did work reasonably reliably, but I would never want such a beast in my shop. paul From cisin at xenosoft.com Tue Jun 16 14:32:50 2015 From: cisin at xenosoft.com (Fred Cisin) Date: Tue, 16 Jun 2015 12:32:50 -0700 (PDT) Subject: using new technology on old machines In-Reply-To: References: <20150615211937.50B0F18C09B@mercury.lcs.mit.edu> <20150616155801.GH30726@Update.UU.SE> <20150616160456.GI30726@Update.UU.SE> , <20150616162407.GK30726@Update.UU.SE> Message-ID: On Tue, 16 Jun 2015, tony duell wrote: > Quite probably, but the modern mains-side switcher is more > troublesome and a lot less pleasant to repair.

One reason I want to keep the original supplies in my 11's is that they are a lot easier to keep going than a mains-side swticher. Yes, they are switchign regulators, but the chopper works at 30V or so, on the output side of a big iron-core mains transformer. So no lethal voltage around. Using a mains-side switcher in parallel with a heating element would seem to be the worst of both worlds. Actually, no. That honour goes to the PSU in a Zenith MDA monitor which as I said 'combines the efficiency of a linear with the reliability of a switcher'. The design (if you can call it that) of this PSU is to rectify the mains, feed it into a free-running chopper circuit, then a transformer. The output of that is half-wave (!) rectified giving about 18V DC. Note the chopper free-runs, so there is no regulation applied at this point. That 18V is then fed to a discrete-transistor linear regulator. And that's not the end of the 'curious' design. As you know, a linear regualtor compares the output voltage of the supply with a reference votlage. That reference voltage is typically produced by a zener diode. Not in this monitor. It uses the drop across the power-on LED. Which means it is important to use a green LED. Another colour, with a different Vf, and the PSU output is wrong. > Just as you can use a CFL along with a heater for some applications > that call for an incandescent. I once saw a curious lightbulb which contained both a mercury vapour discharge lamp and a filament. The idea was that the latter would provide some red light to go along with the predominantly blue/green mercury lamp. I think the filament was also the ballast for the dischage lamp. Oh well.. The time I need a filament lamp is when I am using it for the electrical characteristics (e.g. using it as a ballast resistor), so no kludge with a CFL is likely to work -tony From ard at p850ug1.demon.co.uk Tue Jun 16 14:46:46 2015 From: ard at p850ug1.demon.co.uk (tony duell) Date: Tue, 16 Jun 2015 19:46:46 +0000 Subject: On the Emulation of TU58s In-Reply-To: References: <55805D6E.8030400@update.uu.se> <55806813.7090704@update.uu.se> , Message-ID: > > On Jun 16, 2015, at 12:31 , Paul Koning wrote: > > Part 1: two capstans spinning all the time, in opposite directions.

Not for something that can write a blank tape (e.g. a 7-track or 9-track), but there were other tape systems that required a formatted tape, and servoed the reel motors to the flux transition rate. Obviously the factory had to use a drive with a different tape speed control system to format the tape. From nf6x at nf6x.net Tue Jun 16 14:52:36 2015 From: nf6x at nf6x.net (Mark J.

Radio Shack sold it as the DMP110, I think Amstrad and Commodore sold them too (probably with different firmware).

A really crazy thing that blasts solid toner from a rod of same by producing a spark from said rod to a fixed electrode. The toner doesn't all end up on the electrode, some goes on the paper. Or at least that#s the idea. Setting one up is an interesting job (I turned a pointed pin to make things a little easier) and the quality is non-existant even when it is working properly. -tony From nf6x at nf6x.net Tue Jun 16 15:02:39 2015 From: nf6x at nf6x.net (Mark J.

Has anyone done that? There's no timing track in the TU58 scheme, but there are magnetic BOT and EOT markers that have to be written so that the drive can identify the tape ends. I assume there are also block headers much like on most floppy disks, but I haven't gotten that deep into the formatting yet. The tape includes the BOT and EOT sensing punched holes, and the cartridge includes the angled mirror behind the tape to allow the holes to be sensed with a right-angled optical path. But the TU58-XA drive mechanism does not include the optical sensor that would be needed to sense tape ends on an unformatted tape. I don't know if this was meant as a way to further cost-reduce the already mechanically simple tape drive mechanism, or if DEC did that deliberately to make sure that non-DEC DC100/DC150 cartridges could not be be formatted in the field, so that users would be stuck buying preformatted cartridges from DEC. If new cartridges with brand new, un-decayed belts could be manufactured, then it should be possible to hack up a TU58-XA mechanism for formatting them. I think there may be a little hole in the plastic casting of the drive where one of the optical sensors might be glued in place, if I recall correctly. Oh yeah, the metal vs. plastic base cartridges were also mentioned in this thread. I've only encountered the metal ones so far. Based on the manual pictures, I think the plastic ones use a shorter belt with a simpler path. -- Mark J.

I was thinking of DG drive (about half-rack size) that I believe had them, but I"m not sure of the date of manufacture. Does this apparent lack of start-stop on a dime drives have anything to do with the decline in tape as a working medium (as opposed to a backup or distribution medium)? This is obvious when one looks at an OS such as UNIX or PRIMOS; the tape was treated as pretty much an archival device.

Some do. I remember using IBM tape drives on a 360 Model 44 that were amazingly badly designed. Once ran across a Honeywell drive (7-track) that had a 'vacuum capstan'. The capstan wheel had a vacuum path through the axle and then transferred the vacuum out to holes around the perimeter. So rather than a pinch roller or rubber frictional surface on the capstan to grip the tape, it was a vacuum holding the tape to the smooth metal surface of the rotating capstan. Or was this common on higher-end vac-column drives?

Good point. I didn't even think about writing. Stupid of me. :-) Anyway, it seems the drive do some clever computations to figure out how to keep the speed constant.

Seriously, that is the strangest supply design I've ever heard. That doesn?t seem so bad. Diodes have well defined forward drops, and it certainly is not unprecedented to use the forward drop of, say, a plain silicon rectifier as a reference, or as a fixed drop where that value is needed. The same goes for LEDs. Of course it depends on the material (band gap voltage) which means it depends on the color. While this particular thing is a bit odd, it seems like a clever optimization, eliminating a part by having one that was wanted anyway do two jobs. Sort of the hardware equivalent of reusing a instruction as a constant ? which I understand was done in some PDP-8 device drivers (the DECtape driver comes to mind). paul From tmfdmike at gmail.com Tue Jun 16 19:52:23 2015 From: tmfdmike at gmail.com (Mike Ross) Date: Wed, 17 Jun 2015 12:52:23 +1200 Subject: using new technology on old machines In-Reply-To: References: <20150615211937.50B0F18C09B@mercury.lcs.mit.edu> Message-ID: On Wed, Jun 17, 2015 at 1:54 AM, tony duell wrote: > It's also that this is the 'classic computers' list.

Staying slightly on-topic, working on serious wire-wrap backplanes can get a bit hairy. We probably all have hand-wrapping tools, and can do the occasional repair or patch as required. But... 'remanufacturing' has become part of preservation movements in general; 'preservation/re-creation' might be a better name. The ultimate example of this might be from the railway world. A famous class of British steam locomotives - the A1 Pacific - had become extinct; all were scrapped before railway preservation really became a Big Thing. So, enough enthusiasts got together and they *built* one. >From scratch, from raw metal: http://www.a1steam.com There are various bits of DEC hardware that are extinct, or in critically short supply. I would love to have a TC15 DECtape controller for my pdp-15s; fat chance of ever finding one. Ditto for memory for my KL10. Oh sure, we can make modern functionally equivalent replacements, like Guy S, LCM etc, have done. But it's not the same... DEC backplanes were largely wire-wrapped by machine; I've seen pictures. If the interest was there, it should be possible to restore or re-create the machines used by DEC to manufacture backplanes. From there, it's a relatively small step to source, or manufacture new batches of, the modules etc. needed to populate them Has this ever been seriously considered, or mooted as a possible co-operative venture for a group of us?

DECtape has a timing track, but that can be written on site and simply runs the tape takeup motor at its design speed, as far as I can tell. The reel dimensions of DECtape ensure that the speed doesn?t change all that much (min : max diameter ratio is rather modest). paul From nf6x at nf6x.net Tue Jun 16 20:49:55 2015 From: nf6x at nf6x.net (Mark J.

On this topic, I'm particularly curious about remanufacturing of consumables such as magnetic media, printer ribbons, etc. Not only are supplies of unused consumables monotonically decreasing, but even remaining ones are succumbing to shelf rot (case in point: TU58 cartridges, and particularly their drive belts). In many cases, it may not be strictly necessary to manufacture the entire item. For a TU58 cartridge, the baseplate, case, reels, etc. may be quite usable. The tape probably needs to be replaced, but maybe a particular formulation of common audio tape could be used instead of manufacturing tape from scratch. The belts would certainly need to be manufactured from scratch. In other cases, even where the item needs to be manufactured from scratch, might it be acceptable to use modern methods to manufacture authentic-ish replacement consumables? If somebody figured out how to create suitable magnetic material and binder for floppy disk media and apply it to mylar sheets, for example, maybe a laser cutter could be used to cut out various kinds of blanks (5.25", 8", soft-sectored, various hard-sectored configurations) without the tooling cost of punching dies that would make more sense for mass production? Would the mentioned automatic wire-wrapping machine need to be recreated in a period-correct manner, or would it be acceptable to make one using modern expedient hardware in order to use it to create new authentic reproductions? What sort of concessions could we accept for the lack of authentic components to be used? In the case of a locomotive, there are an awful lots of parts that could be authentically remanufactured in a regular machine shop (obviously, large forgings and the like would be more challenging!). But in the case of a computer using particular no-longer-manufactured semiconductor components, the thought of bringing up a suitable semiconductor fab to build those components would be economically unrealistic. -- Mark J.

Seriously, that is the strangest supply design I've ever heard. I don't know if it was ever published [1], but I should have a reverse-engineered version somewhere. When I unpack it (after the move...) I will see about getting it scanned. It really is a crazy design. [1] There was the standard 'safety component' warning telling you only to use the parts specified in the service manual on the back cover. But I was totally unable to obtain said service manual. -tony From ard at p850ug1.demon.co.uk Tue Jun 16 23:19:06 2015 From: ard at p850ug1.demon.co.uk (tony duell) Date: Wed, 17 Jun 2015 04:19:06 +0000 Subject: Components Data Books In-Reply-To: References: , Message-ID: > Mine too!

True. But you don't need either to build and test the oscillator circuit. The 7440 is an output buffer, if you want to build a test version of the entire module you could stick a '20 there or just about any other TTL inverting gate. But I was thinking of just testing the oscillator part which is Q1 and Q2 (again the other 2 transistors are buffers) The preset clearly sets the frequency. You could build the oscillator with say a 1k resistor there at least to put a 'scope on various points to understand how it works. > I am really used to RF circuits so am puzzled there is no inductor.

OK, I sort-of forgot the smiley, but only sort-of. The problem is that people try to understand a circuit by throwing it on the simulator and really don't understand what is going on at all (this assumes the simulator gets it right which is not always the case). I prefer to think about it. work out how the capacitor (there is only one!) charges and discharges, since that must be the key to the oscillations. -tony From michael.99.thompson at gmail.com Tue Jun 16 18:29:37 2015 From: michael.99.thompson at gmail.com (Michael Thompson) Date: Tue, 16 Jun 2015 19:29:37 -0400 Subject: PDP-12 Restoration at the RICM Message-ID: > > Date: Mon, 15 Jun 2015 19:42:42 -0400 > From: Michael Thompson > To: cctech > > The M452 creates a 220 Hz clock for the TTY transmitter and a 880 Hz clock > for the TTY receiver. > The M405 for the DP12-B serial port generated a clock that is 16x the baud > rate which is then divided by an M216 module. > > Michael Thompson > > Just to prolong this discussion...

(and please stop sending me on wild goose chases) The 4702 is a well-known baud rate generator IC, basically a crystal oscillator and divider chain in one package. It generates 16" baud rate outputs as needed by most common UART chips. As you imply it wasn't really contemporary with the PDP12, but in this case there is 'provenance'. I do not believe it is a replacement for just an M405 though. The M405 is a simple crystal oscillator, the output is at the crystal frequency. Now supposing you wanted 1200 baud. You need 19200Hz at the (16*) input to the serial circuitry. I've never seen a crystal that slow. There are 32768Hz crystals, of course, and then we jump to 100kHz and up. So I woulg guess the original design was to use an M405 and another module (perhaps another M216) as a divider. -tony -- Michael Thompson From billdegnan at gmail.com Tue Jun 16 23:43:17 2015 From: billdegnan at gmail.com (william degnan) Date: Wed, 17 Jun 2015 00:43:17 -0400 Subject: OT?

Such as Rod's new front panels for the 8/e. Or the various replica kits for early micros. One computer I could imagine would sparc interest is a new PDP-6. Not sure how that would materialise. I have a theory as to why it hasn't happened yet though. And that is lack of skill. Take an average sized Swedish town and you can probably scrounge up a fair amount of welders, carpenters, painters and metalworkers willing to work on a fun medium to large scale project such as restoring trains, cars and even whole factories. And given the number of "industry heritage" museums in Sweden it's a fairly big group. But finding the a good sized group of people with the right skills for wirewrapping a large scale backplane and populating it with period correct hardware... much harder I think. There are other problems too, finding a big chunk of metal to machine a new crankshaft is not so hard. Where do you find enough germanium transistors for a PDP-6 (I'm guessing that is what was used, and I'm also guessing that they are less common today, please correct me if I'm wrong) I would love to work on such a project though! /P From hilpert at cs.ubc.ca Wed Jun 17 03:12:46 2015 From: hilpert at cs.ubc.ca (Brent Hilpert) Date: Wed, 17 Jun 2015 01:12:46 -0700 Subject: using new technology on old machines In-Reply-To: <018a01d0a884$c050e1e0$40f2a5a0$@gmail.com> References: <20150615211937.50B0F18C09B@mercury.lcs.mit.edu> , , <037901d0a845$5ae76bb0$10b64310$@gmail.com> <018a01d0a884$c050e1e0$40f2a5a0$@gmail.com> Message-ID: On 2015-Jun-16, at 3:35 PM, Dave G4UGM wrote: >> -----Original Message----- >> From: cctalk [mailto:cctalk-bounces at classiccmp.org] On Behalf Of tony > duell > >>> .. its also a nasty hybrid design with DC biased NPN and PNP >>> transistors.

I think you could characterise it as: - Q1 & Q2 form a two-stage direct-coupled non-inverting amplifier from Q1-B to Q2-C. - C5, the main timing cap, is thus effectively in AC positive feedback, as one would expect for an oscillator. - R9 (the R between Q2-C and Q1-E you were questioning) provides DC negative feedback, presumably to help stabilise and fix the circuit characteristics, as some measure of stability is going to be needed for a baud-rate generator. Note it also has it's own voltage regulator in D1 to D4. At first glance I thought R9 might be there to provide some hysteresis in the switching thresholds for the RC charge/discharge but it looks like it acts in the opposite direction to that. The base circuit of Q3 (the first stage of buffering) will draw current from the high-impedance side (R8,R9) of the oscillator output, pulling up the C5,R9 junction when Q2 is off, so it will probably affect the oscillator and be necessary to get the 'proper' functioning of the oscillator portion of the circuit.

Umm, perhaps not the best choice! The original PDP-6 was known for being, ah, flaky. There's a reason DEC sold less of them than any other DEC machine! (Nothing wrong with the _architecture_, mind - the KA-10, which is basically identical, was _very_ successful. It was purely the implementation.)

I'm clearly never going to be any good at analog stuff! ;-) Even with what looks (on the surface) to be a wonderfully clear explanation of how the circuit works, I still can't really grok how it operates! I mean, I can tell from the polarity on the cap that the collector of Q2 must be at a higher voltage than the base of Q1, but I am utterly failing to understand how the cap discharges through Q2. And as the cap charges (i.e. the voltage across it increases), how does the voltage on the base of Q1 increase - surely it must be decreasing (since it's tied to the negative side of the cap, which is experiencing a voltage increase across itself)? Like I said, I apparently don't have the gene for analog... :-) Noel From dave.g4ugm at gmail.com Wed Jun 17 09:31:30 2015 From: dave.g4ugm at gmail.com (Dave G4UGM) Date: Wed, 17 Jun 2015 15:31:30 +0100 Subject: using new technology on old machines In-Reply-To: <20150617140815.7AE7718C0A2@mercury.lcs.mit.edu> References: <20150617140815.7AE7718C0A2@mercury.lcs.mit.edu> Message-ID: <085001d0a90a$4dbea050$e93be0f0$@gmail.com> > -----Original Message----- > From: cctalk [mailto:cctalk-bounces at classiccmp.org] On Behalf Of Noel > Chiappa > Sent: 17 June 2015 15:08 > To: cctalk at classiccmp.org > Cc: jnc at mercury.lcs.mit.edu > Subject: Re: using new technology on old machines > > > From: Dave G4UGM > > > I found it easier to think of it in DC terms.

That's AMAZING! I never had RK06es (just RK07s -- DM has them now), but I hope someone somewhere does and you'll *never* find an alignment pack on purpose when you need it.

As far as I know, in special machines mounted on slabs on stone weighting tons, standing on dampeners, so that you had absolutely vibration free environment, and then a very precisely controlled head control system that could write the tracks at the exact place they should be. I think the alingment packs even have some tracks intentionally offset from true center in order to check signal strength when heads are slightly off track as well. Same kind of equipment was used to actually do the formatting of disks, as they cannot be formatted by the disk drives themselves.

On a special rig, I'm pretty sure. I don't know how the RK06 alignment pack works, but I am familiar with the RK05 (our machine had them, and we had to realign one after a head crash), and I assume it's probably similar; it had to have been created on a special rig (the exact nature of which I don't know, but I know a normal drive couldn't write it). For the RK05, the alignment pack has alignment tracks with alternating sectors written a couple of thousandths of an inch offset from the track's nominal center line; when one watches the head's output on a 'scope (at a timebase sufficient to show pairs of sectors), if the output for both sectors in a pair is at the same amplitude, the head is correctly aligned. If not, it's easy to see on the 'scope - one has higher output than the other.

Well, micro-B is the better choice since it is designed for more plug cycles than mini-b, designed to minimize wear on the socket and instead wear out the (cheap, easy to replace) cable and it actually locks in the socket, so is much less likely to slip out.

The RK06/07 do not have embedded servo. There are 2 disks, 4 surfaces in the pack. One is a dedicated servo surface. That cannot be rewritten in the field, AFAIK the data surfaces can be reformatted. > > Incidentally, I once saw a procedure (maybe HP) for rewriting the servo surface of > > a fixed/removeable drive in the field.

Sure. The low-track-density drives like the RK05 (HP7900, IBM whatever) don't have a servo signal on the disk. They have an optical position transducer on the positioner for head position feedback. So they can get the heads into position on a totally blank disk. And thus can reformat such a disk. No the procedure I was thinking of was to re-write the dedicated servo surface on the fixed disk stack of a fixed/removeable drive that used a servo signal from the disk. I am pretty sure it was an HP drive, maybe the 7905 or 7906 (I don't have either). -tony From paulkoning at comcast.net Wed Jun 17 13:06:25 2015 From: paulkoning at comcast.net (Paul Koning) Date: Wed, 17 Jun 2015 14:06:25 -0400 Subject: RK06 alignment pack In-Reply-To: <5581B367.7020208@update.uu.se> References: <20150617153925.8348D18C0A2@mercury.lcs.mit.edu> <20150617163619.GQ30726@Update.UU.SE> <5581A6A0.3070300@update.uu.se> <5581B367.7020208@update.uu.se> Message-ID: > On Jun 17, 2015, at 1:50 PM, Johnny Billquist wrote: > > On 2015-06-17 19:40, tony duell wrote: >> [Writing alignment disks] >>> As far as I know, in special machines mounted on slabs on stone >>> weighting tons, standing on dampeners, so that you had absolutely >>> vibration free environment, and then a very precisely controlled head >>> control system that could write the tracks at the exact place they >> >> I have an idea that some of these units used an optical interferometer to >> determine the head position > > Quite possible. But it also requires the movement control being different from a standard drive, in order to drive at the precision, as well as the feedback from the inferometer. Interferometer would make sense, at least for drives of that era. I think modern drives have track spacings small enough that a visible light interferometer may not be sufficient any longer. > ... >> Incidentally, I once saw a procedure (maybe HP) for rewriting the servo surface of >> a fixed/removeable drive in the field.

True, but an RK05 doesn?t have servo data on the platter; positioning is done by reference to an optical widget in the drive. So it depends on mechanical reproducibility being significantly better than the track spacing. Higher density drives use on-pack servo to avoid that constraint. And embedded servo avoids an additional constraint: accurate positioning of one head relative to another. paul From robert.jarratt at ntlworld.com Wed Jun 17 14:46:33 2015 From: robert.jarratt at ntlworld.com (Jarratt RMA) Date: Wed, 17 Jun 2015 20:46:33 +0100 Subject: using new technology on old machines.

The microdata unit was actually a version which output control signals, rather than a measurement head like this video, so that their logic could step the positioner. Write logic which was not part of the drive was used when it was in manufacturing mode to write the servo on the drive before shipment.

While the cap charges, it steals the base current which would otherwise have gone to Q1, thus keeping Q1 turned off. When the cap nears the end of the charge, more current goes to the base of Q1 which turns on, turning on Q2, which raises the voltage over R8 and R9. Since the voltage on a capacitor cannot change instantaneously, the voltage on the base of Q1 rises while the cap discharges through the base of Q1, keeping it hard on. As the cap discharges and charges in the reverse direction, the base current of Q1 decreases and ultimately Q1 turns off, turning off Q2 and lowering the voltage over R8 and R9, and the cycle starts over. For the circuit to work, I think (I may be wrong) the base current supplied to Q1 by R5 and the pot has to be not quite sufficient to turn it on. Also the cap is reverse charged for one half cycle. I believe this is a classical astable multivibrator circuit, but not the more common one with two cross-coupled transistors with capacitors from the collector of one to the base of the other. The DEC circuit I think can be seen a lot in old Siemens application books from the 1960s, such as may be found here (note German books): http://rainers-elektronikpage.de/SIEMENS-Fach---u_-Datenbucher/siemens-fach---u_-datenbucher.html /Jonas > > At this point the cap is then charged (or discharged) in the reverse > direction via Q2, D5 and R4 until Q1 turns off..... > > >> At first glance I thought R9 might be there to provide some hysteresis in > the >> switching thresholds for the RC charge/discharge but it looks like it acts > in the >> opposite direction to that. >> >> The base circuit of Q3 (the first stage of buffering) will draw current > from the >> high-impedance side (R8,R9) of the oscillator output, pulling up the C5,R9 >> junction when Q2 is off, so it will probably affect the oscillator and be >> necessary to get the 'proper' functioning of the oscillator portion of the >> circuit. > I included that in my LTSpice model.... > ... but it doesn't actually have that much effect... > > Dave > G4UGM > > From nf6x at nf6x.net Wed Jun 17 17:57:48 2015 From: nf6x at nf6x.net (Mark J.

If anyone here does get one, I've got a simple Arduino UNO program that interfaces to the parallel output and sends fully decoded information over USB at quite high speeds. The M-1000-L is a great reader, very reliable, and easy to work on too (I did a little routine maintenance, but mine was in 100% working shape when I got it). Here's a video: https://www.youtube.com/watch?v=N27Mr199I7g I'm also working on getting a cable made to hook up to the M843 CR8-E punched card reader interface for the PDP-8/E, but that's a project for another day (year?).

Are the readers in question these ones in Canada? http://www.vintage-computer.com/vcforum/showthread.php?45888-FS-Documation-M1000-Card-Readers If so, the presumed cost of shipping is the main thing that has kept me from adopting one of them. Well, that and being in debt at the moment from other recent acquisitions. And not having a clear space to set one down. And not having a keypunch, let alone room for a keypunch in my tiny little packed-full house. But I do think they look quite cool! And if I find solutions to all of those impediments before you find loving homes for all of those readers, I may yet adopt one of them. I was born just late enough to miss using punched cards, so I think that experiencing them would be fun since I've never learned otherwise by needing to use them in anger. -- Mark J.

I don't like driving long distances (despite commuting about 20,000 miles per year), and I don't particularly like traveling in general, either.

That has been done before for production purposes. I kid you not. Happened in Switzerland during WW2. Due to the war, coal was a bit in short supply, but Switzerland already back then had plenty of (hydro-) electric power, including on the railway grid. So they converted a few steam locomotives to steam-electric by replacing the firebox with electric heaters. IIRC it was only a few locomotives and they were mostly used for shunting work.

I'd have directed you to http://www.vulcantothesky.org/ if Rob hadn't already. Sometimes, though, it flies near places not on the official list - for example, I've seen it fly almost over our house (we live near Elvington) on two different Fridays in the last month or so. Presumably in transit to some other show. Sadly, on the first occasion it flew circuits for a quarter of an hour, but I didn't hear it (or realise it was the Vulcan) until my wife said something like "Oh, that triangular aircraft has been flying around a bit for a while." (We often get noise from Elvington and sometimes I tune it out.) I watched it fly a couple of circuits before I thought to fetch the camera - by which time it was almost out of sight. On the second occasion it was so cloudy I couldn't get a decent shot.

About 15 years ago I set out to recreate the necessary letters and digits from the font for one of the PDP-11 sites. With some small experience of font design I quickly realised it's quite different from Helevetica in a number of aspects, and it took me a while to get it right. In fact I'm not sure I got it exactly, but Ned Batchelder did, so I never went back to it. My early attempts at PDP-11 logos are at http://www.dunnington.info/public/PDP-11/ if you want a laugh. -- Pete Pete Turnbull From captainkirk359 at gmail.com Thu Jun 18 08:54:49 2015 From: captainkirk359 at gmail.com (Christian Gauger-Cosgrove) Date: Thu, 18 Jun 2015 09:54:49 -0400 Subject: Front Panels Personal Update In-Reply-To: <20150618115440.GZ30726@Update.UU.SE> References: <55825BDD.6050501@btinternet.com> <20150618115440.GZ30726@Update.UU.SE> Message-ID: On Thursday, 18 June 2015, Pontus Pihlgren wrote: > > The article pointed to by URL above specifically state that it isn't. > > /P > Yeah, I realized that once my phone's *bleep* internet actually loaded the page... about two minutes after I sent the mail.

I feel kind of miffed that I've not really gotten the chance to see any really "cool planes" flying.

I honestly can't really tell if it is the Lancaster by looking at it (my eyes are shit), but the sound is sufficiently different from any5thing else there's little doubt. Though I may have mistook the B-25 or C-47 for it. Did you get a chance to see both of the flightworthy Lancasters together last year? I didn't since I'm not in the UK and the time that FM213 was over in the UK intersected with my university terms. Regards, Christian -- Christian M.

The only reason I know about the article was due to Google, but that was because I used to work for ArcSight and we were taken over by HP. I wanted to make a faux ArcSight logo in the image of the old DEC logo for a co-worker who retired early from HP. I made my faux-logo did using Helvetica. His story was interesting. He worked for Tandem. Was bought by Digital. Was bought by Compaq. Was bought my HP. Took early retirement. Found job at ArcSight. Worked there for a few years and then was assimilated by HP (again.) It was amusing for him to see everything come full-circle.

Looks like it will be a perfect fit. It's quite a bit brighter than the old panel. Almost a "glossy" vs "mat" type of difference. Looks great though. Some comparisons to my DEC PDP8/m and a re-branded (Computer Controls) 8/m panel can be seen here: http://www.dvq.com/DEC-panels/ The C/C computer's panel is a little faded, not to mention the paint flaking off. The DEC 8/m is not faded, but is a mat finish. The DEC 8/m is actually mounted on an 8/e switch panel (and chassis) as it uses incandescent lamps. The new panel is going on a chassis that has no panel. I still need to fabricate a switch board for it. I have played with 3D printing switch handles with OK results. Just have to find the actual slide switches with the handle brackets, or make some. Looking forward to an 8/f panel, and hopefully some bezels from Rod.

Yes, I'm familiar with the nickname. The pilots were called "sled drivers". ;-) The start cart was amazing as well. 2 Buick V8 engines made *one* start cart and were required to start the J-58. I can imagine the racket while starting it up. I also found it interesting that while taking on fuel during in flight refueling the SR-71 became thrust limited and required lighting one of the afterburners (at minimum) to be able to maintain flight while attached to the tanker...the asymmetric thrust made for interesting times.

It is useful to be able to find data on the web. When I have an obscure part it is a lot easier than trying to work out which data book to buy and where to get it from Mind you, I don't find google very useful. 99%+ of the hits are companies that claim to be able to supply the device. Considering the one time I contacted such a company about an obscure custom IC they asked me what package and how many pins (for a device that had only ever existed as a 22 pin DIL), I got very suspicious as to what they would actually be supplying... I find http://www.datasheetarchive.com/ to be a good first place to look. But IMHO on-line data sheets should be in adition to paper data books, not a replacement for them.

I also seem to remember that this pack is used with a special alignement meter, not a 'scope.

Not quite within these rules, but here are two cases of old computers showing drawings of themselves back when they were new: Alan Kay's PhD thesis was about the FLEX Machine he developed with Ed Cheadle. These "screen captures" include a drawing of the the machine itself from around 1968 or 1969: http://gagne.homedns.org/~tgagne/wp-content/uploads/6.jpg Here is my own Merlin 2, a 68000 based Smalltalk computer, with a drawing of itself in 1987: http://smalltalk.org.br/fotos/inova11.jpg Drawing with a keyboard was awkward enough that I didn't bother making the chip layout very accurate, not the drawn keyboard either. The colors are wrong because I was playing the the color pallet after the drawing was finished (http://smalltalk.org.br/fotos/inova12.jpg shows a different setting) and I don't have a picture of the setting where the boards are green and the keyboard white, unfortunately. The drawing also shows the original Ethernet based configuration instead of the one with the adapted PC bus on which the drawing is being shown. -- Jecel From ball.of.john at gmail.com Thu Jun 18 19:02:42 2015 From: ball.of.john at gmail.com (John Ball) Date: Thu, 18 Jun 2015 17:02:42 -0700 Subject: Documation card readers for sale In-Reply-To: Message-ID: Just a heads up that both units are now pending a sale.

The general procedure was you commanded the drive to seek to a particular cylinder where the alignment pattern was recorded, and slipped safety pins into the positioner to prevent sudden movements. Then you loosened a couple socket head screws, there was a rod with an eccentric tip that was slipped into a slot in the head mount, and twisted, which crept the head in and out a tiny amount. When you liked the meter reading, you then tightened the screws and moved to the next head. I watched this being done a number of times.

When I visited ALR, a company in Irvine that evolved into making PC type servers and were absorbed into Gateway (name still is used) had a lab with a lot of hardware stations, and for the time good networking. At about noon or so one one of my visits for Sun Microsystems, about a dozen of the engineers showed up and proceeded to pull out hardware and cables, and displays at various stations and hooked them all up pretty quickly. This was in about 92 or 93, I'd guess. They converted the lab into a big Doom game for about an hour. I also found out the best time to round up and have casual consultations with them about things I wondered about with some systems.

If you can find real TTL, yes, I would say so. It's less static-sensitive and it's more tolerant to things like hooking two outputs together by mistake. But note that there are many chips that have more or less TTL interfaces (TTL voltages, TTLish numbers, and in some cases switching thresholds) but are actually CMOS - the 74ALS series comes to mind.

The pack recently mentioned was, I think 74LSxx TTL which is probably the most common and should in most cases be capable of replacing standard TTL. The other advantage of TTL is that is quicker.

It's a hex height DEC-type board with the ejector handles. Connections to fingers on A and B as you might expect, also the grant continuity strapping on C and D, grounds on D (only) and a couple of signals on C (I've not figured out what yet).

The main RAM array is 4 rows each of 32 4164-like DRAMs. There is a second block of 28 such DRAMs, presumably 7 bits for each row of the main array to provide the ECC bits. And then a further single RAM off to one side. The DEC MS730 doesn't seem to have this, and I wonder what on earth it is for. Rest of the board is TTL drivers, etc. There are 2 LEDs, one green, one yellow. And a momentary pushbutton switch. I have no idea of the functions of those. Does anyone recognise this board?

I have no idea of the functions of those. That switch may well be latching (alternate action). I wasnt't pressing it hard enough. It seems to be wired directly to the yellow LED (amongst other things). I have found a mention of this board in an 11/750 FAQ (not surprising, I think the same 1M boards can be used in the 11/750 and 11/730). It appears that in normal operation both LEDs are on. Pressing the button turns off the yellow LED and completely disables the board. Quite why you'd want to do this I do not know... Oh, and it mentions a 'spare RAM chip in a socket on the board'. All RAM on my board is, indeed, socketed. If this is just an unused chip to substitute if one fails then I think I've seen it all... -tony From nf6x at nf6x.net Sat Jun 20 10:11:41 2015 From: nf6x at nf6x.net (Mark J.

I don't recognize that board, but I thought I'd point out the non-DEC memory in my 730. It uses Camintonn CMX-750 memory boards, and I have a CMX-750/730 installation manual that I can scan. I plan to scan it for Bitsavers and Archive.org anyway, but it can jump higher in the queue if anybody has an acute need for it. I pulled one board out of my machine to look at it, and it does not appear to have that oddball extra RAM chip.

In my system, the M9302 bus terminator (dual) and M7454 TU80K (quad) are in the same row. Would this imply that I could replace the M9302 with a BC11 cable to add an expansion cabinet without losing any of the functions already installed in the CPU cabinet?

The M9302 is in a 'Unibus Out', you can plug a Unibus cable in there to link to an expansion box. The official way (as I think I mentioned the other day) involved special dual-height cards at each end with 3 40-way Berg-type cables linking them. But the cards were just connectors, not even buffer chips. It being easier to route 40 way ribon cables through the cable pan rather than a BC11A... > already installed in the CPU cabinet?

It could, other than the fact that I would like to keep it in the half-rack, so I would have to remove the TS05 drive to have somewhere to fit the expanison box. In any case the TSU05 could go in said expansion box if I ever need it, I think. My TS05 needs a bit of work to get it going, and I do wonder how useful it would be.

Incidentally, the RAMs are all soldered on my Camintonn boards. All the RAMs (but not the buffers) on the NatSemi boards are in sockets. And I am not sure this is a Good Thing, they are not good quality sockets at all. They're the very cheap ones that make contact with one side of the IC pin only. But replacing the lot with turned pin is something I will only do if I start having RAM problems on those boards. I've done a little buzzing out with an ohmmeter : The green LED + a 270R resistor are across the 5V line (which is presumably the battery backed memory supply line. if you have that optio). I assume this indicates the board is powered up. The moving contact of the switch is grounded. One of the other contacts of the switch goes to the yellow LED + 270R to +5V. So as suggested, the yellow LED indicates the state of the switch. The other contact goes into the logic. I've not traced it all out yet, but it would appear to disable many of the buffers when it is low (i.e. when the yellow LED is off). So the idea that the yellow LED is on for normal operation and the switch can turn it off and disable the board makes a lot of sense. That 'extra' RAM gets power, but nothing else. As far as I can tell none of the other pins go anywhere. Isn't that a bad idea, to have a MOS device with all inputs floating? I would have thought it would have been better to tie eveything (including the +5V pin) to ground, or to power the RAM but have pull-up resistors on all the inputs. -tony From scaron at umich.edu Sat Jun 20 10:57:46 2015 From: scaron at umich.edu (Sean Caron) Date: Sat, 20 Jun 2015 11:57:46 -0400 Subject: 6 historic tech items that were rescued from the trash In-Reply-To: <20150620081319.10f98fa6@honcho.bcwi.net> References: <20150620081319.10f98fa6@honcho.bcwi.net> Message-ID: I have gotten some of my best stuff from the trash ...

I think that will depend strongly on the individual kid in question, who might view the minicomputer either as a dusty obsolete boring thing, or a fascinating machine unlike anything (s)he presently takes for granted. If you have a kid and a minicomputer, and your kid shows any interest in that dusty old box, then run with it. If not, then find something else that catches their interest in a way that can trick them into learning to think creatively and solve problems. The end result is much more important than how you get there. -- Mark J.

Maybe Erik would consider adding a category on VCF for build logs? If not, there's nothing stopping you from posting a new thread in an appropriate category there. Though if the build happens to be off-topic for VCF, it might get more attention on a more closely-related forum than in the off-topic area on VCF. For R2-D2 robot replica building, maybe there's some robotics or maker forum where it will get the most attention and participation? Or maybe you would consider giving the robot an LSI-11 for a brain so it can sneak into VCF? :) Twitter also has its place for our activities, but it's best suited for immediate interaction around a very short "Hey, look at my cool thing!" posting which will quickly drop into obscurity.

(Now that I think of it I'm not sure what version of the power supply I have in my 2113B). The details for that are covered in the 5061-1356 section of the 92851-90001_Jun79_9.pdf manual referenced below starting on page 84 of the PDF. As described in section 3-9 on page 105 of the PDF the Power Fail Recovery System (PFRS) option consists of the Battery Charger Board (A3A3) and the Battery Backup Board (A3A4) which are mounted internally in the power supply, and the external mounted Battery/Status Assembly. If the PFRS option is not present the Jumper Board (A3A4) is installed internally in the power supply instead of the Battery Charger Board (A3A3) and the Battery Backup Board (A3A4). If you open up your system far enough to remove the lid on the power supply you can visually inspect the installed boards to determine whether or not the PFRS option is installed in the power supply. The battery pack over-temperature thermistor is integrated into the battery pack. It ends up being connected to the TEMP1 and TEMP2 signals shown on the Battery Charger Board (A3A3) schematic Sheet 6 on page 136 of the PDF. If the PFRS option is not installed the Battery Charger Board (A3A3) is not present and there is nothing that would connect to the battery pack thermistor so it is not necessary for the operation of the power supply. If the PFRS option is installed but the thermistor or resistor equivalent is not connected the CPU will power on but will not be functional. I think all of the front panel lights turn on and none of the switches have any effect. It's been a long time since I looked at that in detail to figure out what was going on. I think some of the voltages are at the correct level, but maybe the memory voltages are not, and some of the power supply status signals (PSU?, PON?) indicate the power supply is not ready and that holds the system in the inactive state. -Glen On Sat, Jun 20, 2015 at 7:30 PM, Marc Verdiell wrote: > Ah thanks, this is what these are for, thermistors.

I can get another screen made up with the angled markings at switch positions 1 and 6. When you order you can then specify which one you require. The other two are cosmetic and have no impact on operation. Firstly there is sometimes a line around the area where the selector switch is located. Secondly vertical lines dividing up the lamps into groups of three are sometimes present. I can't yet work out if there's any pattern to where they do and dont appear.

The indicator light bulb failed, briefly shorted, and destroyed the transistor that turns the indicator on. An new transistor and bulb, and all is well. We have been chasing a transient problem in the PDP-12 core memory for a few weeks. We checked the timing last week, and it was OK. This time we checked the core voltage and it was a little low. We increased the core memory power supply voltage until the checkerboard starting working without errors. Next time we will explore the high and low limits of the core voltage to find a reasonable center voltage for both core stacks. The next step is to run all of the processor diagnostics and make sure that everything is works. If the diags run OK, it is time to fix the TU56 tape drive and see if the drive and controller work. We visited the RCS/RI crew today to look at their LINC-8 and both PDP-12s. Both PDP-12s are earlier than ours. One has floating-point and an RK05. The other has a really interesting RAM buffered AD converter. -- Michael Thompson From captainkirk359 at gmail.com Sun Jun 21 07:30:48 2015 From: captainkirk359 at gmail.com (Christian Gauger-Cosgrove) Date: Sun, 21 Jun 2015 08:30:48 -0400 Subject: Nopecraft - was Re: OT: learner kits In-Reply-To: <558648E9.7070005@telegraphics.com.au> References: <20150616142638.C8CAA18C095@mercury.lcs.mit.edu> <531BA397-AB2E-4D95-8381-BE54212D59DC@nf6x.net> <6CD3CAEC-4164-4555-AC3B-464D198DF13E@swri.edu> <5584E444.6090008@telegraphics.com.au> <0D1C314F-BEFE-4DD3-86BC-8BD93CB095A2@nf6x.net> <558648E9.7070005@telegraphics.com.au> Message-ID: On 21 June 2015 at 01:17, Toby Thain wrote: > Except with pointless obfuscation and click'n'drool topping. > Did you ignore the whole "Nine Videos on How To Lua" and the "Giant Video of FORTH-ness"? Of course, real "stuff" is much better than pissing around in Minecraft. But hey if you can get a kid to find interest in programming via Minecraft of all things, I say that's still a success. And if you want to complain about something; complain about the fact that the way the Ontario high school's teach programming is ass backwards. Instead of learning actually luseful things about programming, it's "Focus on making pretty forms with Visual Studio". I say that's much worse than turning the same kid loose with ComputerCraft and watching them make something that actually "does something". Cheers, Christian -- Christian M.

Yes, it would be great if we could hook 14 year old kids on programming computers - but really, that happens a *lot* less than we would like it to. Even in the good old days with Apples in the schools, how many young teenagers actually stuck with it after the classes ended? Few, damn few. At least with Minecraft, kids tend to stick with it in (probably due to the community and Youtube). The original poster's son seems to be sticking with it quite well, it seems - so let him run with it. Anyway, I think this has strayed to far from old computers, so I will probably tune out.

The reason you'd want a button to disable the board is when running diagnostics, you can "remove all the non-DEC memory" without physically removing it. Of course it still could be the source of a problem, but at least operational memory boards can be "deleted" so they don't grossly affect the diagnostic code. It's a "feature" to allow customers to buy less-expensive RAM and still have a way to pass diagnostics without fingerpointing from DEC about that "other" board in there. -ethan From ard at p850ug1.demon.co.uk Sun Jun 21 12:08:22 2015 From: ard at p850ug1.demon.co.uk (tony duell) Date: Sun, 21 Jun 2015 17:08:22 +0000 Subject: Looking for info on National Semiconductor RAM board (VAX 11/730) In-Reply-To: References: , Message-ID: > > Pressing the > > button turns off the yellow LED and completely disables the board.

How would DEC know? These boards do not, AFAIK, have any form of machine-readable ID. All DEC could tell remotely was how much RAM was in the machine. And I would hope any Field Servoid could spot a non-DEC memory board if he was looking in the cardcage! Disablng the board would prevent it acting as a data storage area, but if there's a shorted buffer or something it could still mess things up. There is a common bus to all the memory boards, at least in the 11/730. And I know the machine will not behave normally if there are gaps in the physical memory space, quite whether it would run diagnostics in that case I do not know. So I guess you had better have all the DEC boards at the start of the memory space and if you want to make the 3rd party RAM disappear, disable all the boards. -tony From dj.taylor4 at comcast.net Sun Jun 21 09:49:27 2015 From: dj.taylor4 at comcast.net (Douglas Taylor) Date: Sun, 21 Jun 2015 10:49:27 -0400 Subject: Nopecraft - was Re: OT: learner kits In-Reply-To: References: <20150616142638.C8CAA18C095@mercury.lcs.mit.edu> <531BA397-AB2E-4D95-8381-BE54212D59DC@nf6x.net> <6CD3CAEC-4164-4555-AC3B-464D198DF13E@swri.edu> <5584E444.6090008@telegraphics.com.au> <0D1C314F-BEFE-4DD3-86BC-8BD93CB095A2@nf6x.net> Message-ID: <5586CEF7.9010407@comcast.net> On 6/20/2015 8:06 PM, William Donzelli wrote: >> Right.

I have looked in more detail into my machine and its rear connectors. It's a 21MX (2112A), and it has two battery holders at the back. The old batteries even came with it (!). On this machine the battery connectors are just two pronged, + and -, so no thermistor connection apparently. At first glance I thought two other 9 pin connectors were similar to the ones you described and needed to be wired up with the thermistors. But they apparently are totally different things, labeled POWER CONT IN and POWER CONT OUT. After a bit of bitsaver hunting, I gather these are for power control interconnection with optional I/O racks extensions. So I think I am thermistor free. I just need to find new small 12V lead batteries that fit. They are an odd "construction brick" form factor, standard modern gel batteries are too tall. Marc ------------------------------ Glen Slick said: Subject: Re: HP 2113e Battery resistor I have only looked at the "B" version of the power supply as that is what I have in my 2117F. (Now that I think of it I'm not sure what version of the power supply I have in my 2113B). The details for that are covered in the 5061-1356 section of the 92851-90001_Jun79_9.pdf manual referenced below starting on page 84 of the PDF. As described in section 3-9 on page 105 of the PDF the Power Fail Recovery System (PFRS) option consists of the Battery Charger Board (A3A3) and the Battery Backup Board (A3A4) which are mounted internally in the power supply, and the external mounted Battery/Status Assembly. If the PFRS option is not present the Jumper Board (A3A4) is installed internally in the power supply instead of the Battery Charger Board (A3A3) and the Battery Backup Board (A3A4). If you open up your system far enough to remove the lid on the power supply you can visually inspect the installed boards to determine whether or not the PFRS option is installed in the power supply. The battery pack over-temperature thermistor is integrated into the battery pack. It ends up being connected to the TEMP1 and TEMP2 signals shown on the Battery Charger Board (A3A3) schematic Sheet 6 on page 136 of the PDF. If the PFRS option is not installed the Battery Charger Board (A3A3) is not present and there is nothing that would connect to the battery pack thermistor so it is not necessary for the operation of the power supply. If the PFRS option is installed but the thermistor or resistor equivalent is not connected the CPU will power on but will not be functional. I think all of the front panel lights turn on and none of the switches have any effect. It's been a long time since I looked at that in detail to figure out what was going on. I think some of the voltages are at the correct level, but maybe the memory voltages are not, and some of the power supply status signals (PSU?, PON?) indicate the power supply is not ready and that holds the system in the inactive state. -Glen ------------------------------ From mtapley at swri.edu Sun Jun 21 19:01:52 2015 From: mtapley at swri.edu (Tapley, Mark) Date: Mon, 22 Jun 2015 00:01:52 +0000 Subject: Nopecraft - was Re: OT: learner kits In-Reply-To: References: <20150616142638.C8CAA18C095@mercury.lcs.mit.edu> <531BA397-AB2E-4D95-8381-BE54212D59DC@nf6x.net> <6CD3CAEC-4164-4555-AC3B-464D198DF13E@swri.edu> <5584E444.6090008@telegraphics.com.au> <0D1C314F-BEFE-4DD3-86BC-8BD93CB095A2@nf6x.net> <5586CEF7.9010407@comcast.net> Message-ID: <6BD71E4E-5EE0-4939-9F68-15B74AAFE32B@swri.edu> Christian et al, sorry for the somewhat off-topicness: On Jun 21, 2015, at 5:56 PM, Christian Gauger-Cosgrove wrote: > The RPi comes with a free full version of Mathematica?

I believe the version of Mathematica is a full version. It did not come bundled, but here?s the Wolfram page describing it and pointing to the Raspberry Pi foundation (but not to the correct link for downloading mathematica): http://www.wolfram.com/raspberry-pi/ Our Raspberry Pi came with a flash card containing NOOBS, which allowed us to download and install our choice of several operating systems. We chose Raspbian, then downloaded and installed Mathematica. We solved a pretty small amount of trouble getting the icons to show up on the desktop, then I downloaded my largest and most complex Mathematica notebook which ran (well, crawled) without modification. Hm, on investigating, I think it actually is included in Raspbian now. If not, https://www.raspberrypi.org/mathematica-10/ may help. FWIW, Beaglebone Black is rumored to have a Mathematica port in the works: http://community.wolfram.com/groups/-/m/t/386736 Mathematica is similar to Maple from what I hear. I have not used Maple, though. In addition to the TI CAS?s you are familiar with, here is another option: http://maxima.sourceforge.net Free, runs on Windows/Linux/Mac/Android and source is available. I have tested briefly on my Mac OS X.9.5 and on my Moto X cellphone on Androiod 4.2, no problems so far. Likely not as powerful as Mathematica, but certainly has many of the same building blocks, so if you want to test computer-based CAS with little cost/hardware investment, this might be useful. > The mod that does FORTH on a 6502 is a bit dead.

Sounds fun, but I?m a bit nervous about putting in that effort if it attracts him no more than Cardiac in Java did. But I?ll keep the suggestion in mind! I do have a pair of TRS-80 Color Computers and an assembly language cartridge; he showed not much interest there, so I?m not confident the PDP simulations would do much better. - Mark From marc.verdiell at gmail.com Sun Jun 21 19:02:12 2015 From: marc.verdiell at gmail.com (Marc Verdiell) Date: Sun, 21 Jun 2015 17:02:12 -0700 Subject: Place for a build log?

That's a good suggestion. On the R2 group, the Builders Log section was actually added after I suggested it. It is now the most viewed section. But on VCF (that's how you call it?), I think I am way too new to make such a proposal and have it taken seriously...

Anyone remember much about Tru64 + LSM? It's been a while since I've done much with Tru64, and I never used LSM before. I got some new 36GB disks and am doing a fresh install, and wanted to mirror them with LSM, as the SCSI controller is not a RAID card. Initially, the installer picked really stupid defaults, choosing to use only about 3GB of the 36GB available. I was hoping to do something like have the LSM be in total control of the disk, with all filesystems and swap being on LSM volumes. The LSM documentation says this would be called a "sliced" disk. I'm a little rusty on my disklabel specifics, but the Tru64 docs seem to suggest that the 'a' slice is usually used for the / filesystem, 'c' is the whole disk, and g or h is usually used for the LSM private data. So, my questions are: 1. Is it possible to install to and boot from an LSM sliced disk (as opposed to an LSM "simple" disk)? 2. Is it possible to have swap be on an LSM volume, or does it have to be on a slice (like dsk0b or something) 3. Is the 'a' slice strictly required for anything? 4. Would the best (or a good) way to go be to do something like a & b unused, c whole disk, g all the space except 2MB, and h 2MB for LSM data?

Note that the "A" supply used a 12 Volt nickel-cadmium battery pack (per page IXA-1 of the M/E/F-Series ERD), and the charger is a constant-current supply. The pack is not broken down in the parts list but presumably would have contained ten 1.2-Volt cells. The "B" supply used a 14 Volt lead-acid battery pack (ERD IXB-5), so seven 2.0-Volt cells, and the charger is a constant-voltage supply. If you use lead-acid batteries with the "A" power supply, you may wind up overcharging them and shortening their life. -- Dave From mhs.stein at gmail.com Mon Jun 22 00:16:11 2015 From: mhs.stein at gmail.com (Mike Stein) Date: Mon, 22 Jun 2015 01:16:11 -0400 Subject: XH558 - was Re: using new technology etc References: <1186701935.850249.1434725906442.JavaMail.root@md02.topaz.synacor.com> Message-ID: <236C604ADDED4D41B246CB409630D248@310e2> ----- Original Message ----- From: "William Donzelli" To: "General Discussion: On-Topic and Off-Topic Posts" Sent: Friday, June 19, 2015 8:43 PM Subject: Re: XH558 - was Re: using new technology etc >> Don't forget Cromemco: > > I think we can forget Cromemco. > > The original poster wanted examples of minis > "setup and used on one". > I doubt a Cromemco would survive long in flight > service.

Interesting. I can't think of a reason why the two ends would need to be different, but otherwise why do both exist? I've seen M9014s only at the far end of the UBAs on a KS10, so it wasn't taking the place of a BC11. Anyway it'd certainly be easy to make replacements for the M9014 and/or M9015.

Probably more feasible than trying to make more BC11's. Which is another aspect of my interest in these things.

If it wasn't take the place of a BC11 (i.e. proving a path for the UNIBUS >out), what was it doing? OK then I guess it *was* taking the place of a BC11. :-) I just meant it wasn't jumping directly from one DD11 to another, so the "source" end really was three Bergs, not a DD11 slot. I've seen that done only with the fancy flexprint cable, not two paddles and three ribbon cables, so I was kind of assuming that there's some impedance-matching (etc.) problem with using ribbon cables for more than one hop. But then again ... I chose the digital version of EE as my major precisely because I knew I'd flunk Fields and Waves. Transmission lines are black magic as far as I'm concerned!

Thanks for the reply! I'm using AdvFS. You just mean that the partitions don't actually have to conform to any specific convention, right? The AdvFs domains still get defined on disk partitions, if you look at the symlinks in /etc/fdmns/. You can put a symlink to a LSM volume in there too, but the problem I'm running into is that the installer (text-based, because I don't have a graphics card) is fairly insistent upon applying a disklabel that it calculates as barely sufficient to hold the stuff you're trying to install, and wants to use 'a' for boot, 'b' for swap, 'd' for the LSM private partition, and so on and so forth. I'll probably have to resort to setting it up without LSM, then encapsulating it, but again that wouldn't lead to a "sliced" LSM disk. (I think) Might you be so kind as to show the ls -la from your /etc/fdmns/*/, and the disklabel -r dskX from the disks? The documentation suggests that come extra flexibility could be gained by doing a graphical install.

But I can talk about partitions, if you are using the advanced file system then none of the partition rules apply, if you are using the ufs then the traditional layout is this: a - boot partition, mounted as / unlike linux, there is generally no /boot partition b - swap partition c - the entire disk d to g - partitions for other stuff like /var /usr /tmp etc. I have a pair of Alphaservers running Tru64 Unix in a cluster and it boots from a raid set delivered by a RA8000 SAN and three Alphaservers who boot off local storage using a mirror set delivered by a KZPSC (DAC960) or one of its various similar siblings.

It's just a plastic shell containing 10 big C-size cells, 3.5 A.hr each, indeed from the time period it must be NiCd! Now if I can find similar cells I will be able to reconstruct the pack inside the same shell. It will even look like the original. Thanks again. Marc ------------------------------ "J.

Note that the "A" supply used a 12 Volt nickel-cadmium battery pack (per page IXA-1 of the M/E/F-Series ERD), and the charger is a constant-current supply. The pack is not broken down in the parts list but presumably would have contained ten 1.2-Volt cells. The "B" supply used a 14 Volt lead-acid battery pack (ERD IXB-5), so seven 2.0-Volt cells, and the charger is a constant-voltage supply. If you use lead-acid batteries with the "A" power supply, you may wind up overcharging them and shortening their life. -- Dave ------------------------------ From richardlo at admin.athabascau.ca Mon Jun 22 14:20:55 2015 From: richardlo at admin.athabascau.ca (Richard Loken) Date: Mon, 22 Jun 2015 13:20:55 -0600 (MDT) Subject: Tru64 LSM In-Reply-To: <5782C16A7C920E469B74E11B5608B8E76959CF5A@Kriegler.ntdom.cupdx> Message-ID: On Mon, 22 Jun 2015, Benjamin Huntsman wrote: > I'm using AdvFS.

A couple good friends worked for Tandem from very near the beginning, so I know what a Non-stop I looks like. He built one from scrap boards in his basement, too. Also, it is clearly NOT 1990 era, probably much closer to mid-1970's. The cartridge disk drives look a little like double-decker Diablos, with the packs in racks on top of the cabinets.

The cartridge disk drives look a little like double-decker Diablos, with the packs in racks on top of the cabinets. The CPUs remind me of TI machines, but these would be earlier than the ones I had seen. I think the hint is on the back. This is a story of Delaine Donohue retiring from D&B where he created and ran the National Business Information Center and the Central Data Collection Group between the early 70s and early 80s. He retired in ?89, so it?s not unreasonable to assume 80?s vintage in the context of D&B ? although the drives do suggest earlier rather than later in the decade. Figuring out the computers from the date range is more difficult. Before 1978 D&B was still a Xerox (Sigma-5 and Sigma-9) shop; in 1979 they purchased National CSS and plunged into IBM mainframe land. NCSS had a homebrew packet-switching network that talked to IBM and Amdahl iron (and, after the purchase, evolved to be DunsNet), so I suppose it?s possible that these are comm processors ? although IIRC most of the original NCSS packet stuff was PDP-11 based.

What kind of use do you require here for your app -- is that a one-off installation or a more widespread deployment? For a single use your simplest solution might be using similar hardware. ZLX-E2 is the PMAGD-B or HX+ TURBOchannel option (24-bit DirectColor, no Z-buffer, using a Bt463 RAMDAC), also known as SFB+ (Smart Frame Buffer+) after the graphics ASIC. A 5V PCI variant was manufactured under the name of ZLXp-E2, more commonly known as TGA (I don't know offhand what the acronym expands to). Both are supported under Linux, using the `tgafb' kernel driver and a corresponding X11 DDX module. So you might try this instead, chasing a 24-plane PCI TGA board should be doable. The board has no VGA compatibility AFAIK so there should be no odd issues with legacy address decoders or initialisation on non-Alpha systems -- the board should simply sit there quietly until initialised by the kernel driver and then taken over by the X server. The DDX module for the X server might not be built by default for TGA on non-Alpha systems though, so you might have to do some tweaking. Just a thought, maybe it'll help.

I found a few mentions of the D&B setup back then. In the 60s and 70s, D&B appeared to be a loyal IBM customer, even endorsing the 3850-beer can-in-a-pigeon-coop MSS device. I did find a mention that D&B installed a minicomputer network in its local offices in 1976.

I wrote some PDP-11 assembler code which could handle unsigned values up to 2^512 (just under 10^160) plus fractional numbers with 1024 bits that had a precision on the right hand side of the decimal point equal to the integer portion - 512 bits for each. Actually, there were three levels of precision: 128 bits, 256 bits and the maximum at 512 bits. The FORTRAN 77 integer symbols were LU..., MU... and NU... while the corresponding integer / fractional symbols were LX..., MX... and NX..., all allocated as CHARACTER *n variables. These subroutines are designed to be used under FORTRAN 77, so any PDP-11 operating system (such as RT-11 and RSX-11) can easily make use of them. While these routines include ADD, SUBTRACT and MULTIPLY, DIVISION is not available, although that is easily remedied via a FORTRAN 77 subroutine which arrives at the result via the standard approximation algorithm. Also available are ENCODE and DECODE routines to convert between internal binary and external decimal values. In addition, there are routines to convert back and forth between all six sizes of variables and DOUBLE PRECISION floating point or REAL *8 variables. Of late, I realized that a signed variable aspect is required, so I have begun to consider what is needed. ALSO, because I so often run the PDP-11 code under the Ersatz-11 emulator, I will consider supporting the use of six additional PDP-11 instructions (for each ONLY one combination of registers will be used as operands - Ersatz-11 supports a DLL): UMUL16 - unsigned multiple two 16 bit variables MUL32 - signed multiple two 32 bit variables UMUL32 - unsigned multiple two 32 bit variables UDIV16 - unsigned divide a 32 bit variable by a 16 bit variable DIV32 - signed divide a 64 bit variable by a 32 bit variable UDIV32 - unsigned divide a 64 bit variable by a 32 bit variable the UMUL16 and UMUL32 instructions being especially important to perform multi-precision MULTIPLY. I will also consider the possibility of a single PDP-11 instruction to perform multi-precision arithmetic of values contained in memory using that ability of the Ersatz-11 emulator to LOAD a user written DLL, namely to convert many of the PDP-11 multi-precision assembler subroutines to a single PDP-11 instruction which would then be executed using x86 instructions at a much higher speed, sort of like a CIS for multi-precision variables. In that case, much larger sized variables could easily be supported due to the much higher speed of execution. In addition, the (approximately) 16KB of subroutine instruction / data memory within the emulated PDP-11 could be substantially reduced. If there is sufficient interest and support, complete algorithms might be implemented which could directly make use of the x86's huge GB memory to solve particular problems - sort of like a SLAR auxiliary processor CPU (which for example performed an FFT on a KB sized array in virtual memory) implemented in software rather than hardware. I hope that some interest is expressed. Commercial inquiries for a specific algorithm would obviously receive priority, but hobby users are expressly encouraged to express all of their needs as well.

I can understand Elnec's distress over the cloning of their product, but they did themselves no favor by taking the approach described here: "...The manufacturer of the fake BeeProgs stole our logo and intellectual property by manufacturing fake copies of BeeProg programmer. This "product" uses also our software and users of this fake BeeProg are asking for our free technical support. Although the copy of the BeeProg programmer is done well, the manufactures of the fake BeeProg overlooked few details. Result is, the fake BeeProg unit differs from the original, visible for the software. We've used one of these differences - it is not a serial number - and our software could detect this fake hardware. If PG4UW software detects a fake hardware, it shows message "Fake programmer unit detected!" and programmer will no longer work. If you're facing such situation, contact please the vendor, where from you bought the programmer, for full credit return. Or you can take this vendor to court for selling a fake products. We regret, we could not provide any assistance in this case..." In the USA, they would probably end up as the target of legal action, since refusing to do the update is legitimate, but disabling the device is a no-no. It amounts basically to theft of a product from the (unaware) owner--sort of an extra-judicial vigilante killing. This reminds me of early failed floppy-copy-protection schemes. Fortunately, there are solutions to restore functionality to the clone Beeprog. I do not know if the same obtains for the clone Plus. --Chuck From a.carlini at ntlworld.com Tue Jun 23 10:22:47 2015 From: a.carlini at ntlworld.com (Antonio Carlini) Date: Tue, 23 Jun 2015 16:22:47 +0100 Subject: Megaprocessor - built from individual transistors In-Reply-To: References: , <8C0DF182C93A4F169B7285AF2FEF296E@workshop> Message-ID: <558979C7.20003@ntlworld.com> .Apologies if this has already been posted There seems to be someone building a processor from individual transistors: http://www.megaprocessor.com/index.html Estimated size: quite big!

They are not obliged to ensure that their software works correctly on a pirate copy of their hardware. If they add some additional checks, and they trap out on a clone, I doubt that could be considered illegal. They do not try to destroy your device. Their software just refuse to run. And I can't see it other than they are in their right to do that. Talk with the manufacturer of the clone for a software update from them instead.

Ask the manufacturer of the device to fix it. Do you really expect that someone who have nothing to do with the device has any responsibility here? You (or whoever) install software that was not intended for the device on it anyway, and then you blame the maker of that software.

But it won?t wipe the device BIOS in retaliation. What if it accidentally do write something to some NVR just by the process of trying to detect if the hardware makes sense? (We had that problem with NetBSD on VAX 4000 machines for many years, where it tried to probe for some hardware which on that specific machine actually was some NVRAM with parameters that NetBSD smashed.) And I would also hope it would just display a message, and then refuse to continue. Where is the difference?

Jonathan, I think it is _really_ naive to think that the Soviets gained any big knowledge from that old Mainfraimes. The soviets build the sputnik, atomic bombs and intercontinental ROckets w/o to find such things on cuba at all. There was'nt any technological difference betwenn the US and the USSR at this time. Please, please all americans, don't think that russians are stupid. There was always a _really_ big difference between consumer and military electronics at the times of the iron curtain in the USSR.

You do misunderstand the situation. Elnec has publicly stated that it checks for one of the illegal clones and subsequently erases the NVRAM. This is independent of the owner's knowledge or lack thereof, that he's got a bootleg copy. The intent is clear, as is the public statement. They're taking a gripe they have with some Chinese bootleggers and depriving (stealing) the use of your device because it isn't theirs. That is, they've determined that the device isn't legitimate and, as a result, disabled it--in lieu of taking action against a hard-to-pin-down bootlegger. And, as mentioned, FTDI tried the same approach and got burned badly. All one needs is a hungry lawyer--class-action cases can pay off big. --Chuck From cclist at sydex.com Tue Jun 23 12:09:00 2015 From: cclist at sydex.com (Chuck Guzis) Date: Tue, 23 Jun 2015 10:09:00 -0700 Subject: organizing a trip to Cuba In-Reply-To: <20150623163250.GB21341@beast.freibergnet.de> References: <20150623163250.GB21341@beast.freibergnet.de> Message-ID: <558992AC.1080204@sydex.com> On 06/23/2015 09:32 AM, Holm Tiffe wrote: > Jonathan, I think it is _really_ naive to think that the Soviets gained any > big knowledge from that old Mainfraimes. > > The soviets build the sputnik, atomic bombs and intercontinental > ROckets w/o to find such things on cuba at all. > There was'nt any technological difference betwenn the US and the USSR at > this time. I remember that in the day, the Bulgarians (and probably other Warsaw-pact countries) were particularly adept at building virtual clones of US peripherals. In the 70s, a couple of the CDC brass paid a visit and confirmed the story. It was a trade war, in some respects--not just a "cold war". The USSR didn't respect western copyrights and patents, and western countries reciprocated. After 1990, some amends were made (cf. "restored copyright" in the US). It had its bright spots--the West got to hear music by USSR composers (e.g. Shostakovich, Prokofiev) played more often than they would had the works enjoyed IP protection. Doubtless, Western music got a good hearing behind the iron curtain. --Chuck From jdbryan at acm.org Tue Jun 23 13:06:33 2015 From: jdbryan at acm.org (J.

There was actually no possibility to get a proper license or machines even when you wanted to pay for that. Intellectual properties simply haven't existed in the "real life" behind the iron curtain and w/o to invent the hot water again, it simply got copied. Now we have a new single economic system and things have changed. The NSA/GCHQ is spying out people all over the world, officially to fight terrorism (if you belive that), but as it turns out they are always interested in industrial espionage too and even spy out the mobile from not only me, but the german cancelor (terrorist ehy? tought that are "friends"..). Think that's ok for you? (not for me as for most people on the world, but they simplay take the rights to do this which really pisses me of) If yes, for sure you want to call it stupid that IBM still want's to get payd for the old Mainframes, don't you? > > It was a trade war, in some respects--not just a "cold war".

Does that prevent you from loading some other software on said device? How did you get the "broken" software on the device? There is a difference between refusing to run, and trying to destroy the hardware.

Are you saying that it is impossible to reprogram the device with some other firmware after you have tried the version Elnec have which detects your clone?

Thus "brick" the device. (about a decade ago, we had a thread that included stacking algorithms for using dead/unwanted commodity devices as construction materials) Surely any competent designer will provide a way to prevent/recover from that situation! That could consist of a physical switch or jumper that must be manually set before the system can writeover the NVRAM. OR there could be a second boot ROM in the machine that could be jumpered into place to enable booting, perhaps to a limited recovery mode, if/when the primary boot is damaged. OR, in worst case, the NVRAM could be socketed, and a replacement copy could be physically installed. YES, the part(s) could be unsoldered, and replacement soldered in. THAT does not seem like an acceptable recovery requirement. Why are such incompetent designers still employed in the industry? As a classic example of design by marketing, . . . Vault corporation in a matter of minutes set into action (by announcement of "Pro-Lock PLUS") a sequence of irreversible events that eliminated the existence of the company. In an essentially identical situation, of taking retaliatory action upon detection of a "fake". Few are aware that Vault apparently NEVER actually sold a single copy of the announced system.

It could be due to an unforseen situation not considered by the designers. Several years ago a friend of mine bricked at CAR (BMW I believe---it was a high end German car in any case).

It's possible, but as I understand it, reprogramming involves using a PICKit programming tool, something not everyone has access to. The point is that prior to Elnec doing their little act of revenge, the clone programmer worked just fine. Afterwards, not so much. Perhaps an analogy might be deflating all 4 tires and the spare on your neighbor's car because he borrowed your lawnmower and won't return it. Do you have a beef? Sure, you do. Can you vandalize (in a non-destructive way) his property because you have a beef? Most law-enforcement people would take a dim view of this. --Chuck From cisin at xenosoft.com Tue Jun 23 15:05:12 2015 From: cisin at xenosoft.com (Fred Cisin) Date: Tue, 23 Jun 2015 13:05:12 -0700 (PDT) Subject: [RANT] EX-PARROT (Was:False Beeprog.

The incompetent designers that I was referring to are those who made a programmer that COULD be fried. I remember unsoldering a 28 pin ROM for replacement, and was unhappy that it hadn't been socketed. My soldering skills (lack therof) would preclude doing the same on a surface mount device.

But any designer who implements firmware update without considering the possibility of power failure is not qualified for the job. That was my reaction too. Are people seriously saying that even in normal circumstances, you can brick the device? The most typical failure mode being if you get a power interruption while flashing new firmware. If the designers seriously did not take that scenario into consideration, then we have a more broken design than I would allow for. And to respond to the people who said I should re-read the original post where it was stated that it was bricked... Here is the original text, and there is no mention of bricking. "...The manufacturer of the fake BeeProgs stole our logo and intellectual property by manufacturing fake copies of BeeProg programmer. This "product" uses also our software and users of this fake BeeProg are asking for our free technical support. Although the copy of the BeeProg programmer is done well, the manufactures of the fake BeeProg overlooked few details. Result is, the fake BeeProg unit differs from the original, visible for the software. We've used one of these differences - it is not a serial number - and our software could detect this fake hardware. If PG4UW software detects a fake hardware, it shows message "Fake programmer unit detected!" and programmer will no longer work. If you're facing such situation, contact please the vendor, where from you bought the programmer, for full credit return. Or you can take this vendor to court for selling a fake products. We regret, we could not provide any assistance in this case..." Note that the text says "it shows message ''...'' and programmer will no longer work." That by no means means that it is actually bricked. It merely says that the firmware will not continue past that point. Now, if someone actually have one of these devices, and can verify that it actually bricks it, then we can talk. Until then, all I have is the above information from Elnec, which do not suggest anything beyond showing a message, and not continuing past that point. If the manufacturer of the device have not made allowance to recover from a bad firmware installation, then there is a problem. But that is not necessarily something you can blame Elnec for either...

I assume the system can be upgraded in the field through some built in function in the firmware, and that function is also no longer available after installing the "latest" version then. Well, the criminal part is obviously done by the company cloning the device in the first place. Further aggravated by selling it as some other device it is not. So they are fraudulent both to Elnec and to end users. I know that in the US people sue for all kind of things, and sometimes the most amazing things stand up in courts, so I wouldn't be surprised to learn that this could hold up as well, but in my view, Elnec was perfectly in their right to do what they have done. How about leaving it at that then? People can disagree with me all they want.

To me it looks like those are pairs of analog moving-coil meters on the fronts, either side of the blinkenlights, which seems a little odd (I mean sure, maybe one such meter for checking/monitoring power inputs, but even then I'm surprised it would be right there on the front panels). It makes me wonder if these aren't some form of multi-channel data logging devices, rather than a general-purpose computer.

I think those are all disk cartridges, rather than tapes. I was trying to guess what the blurred manufacturer name on the racks might be and find matching pics on the web but no luck so far. Looks like one capital letter followed by a number of half-height letters. I find it odd that the while the drives are mid-70s+, the processor panels look like something from the late-60s or even earlier.

They have effectively destroyed property owned by someone else. The fact that the device they destroyed is counterfeit is completely irrelevant! FTDI learned this the hard way when some drooling MBA decided it would be a good idea to brick people's serial devices. AFAIK, they're STILL suffering for that - as they well should.

I strongly suspect that bricking the fake device is _not_ a side effect, but quite intentional. Detecting a fake copy of their product, loudly proclaiming this find and refusing to work with it is perfectly fine and certainly within their rights. Destroying other people's property is not. They are certainly not the first to try to pull this one. FTDI for one very explicitly bricked fakes of their USB-Serial chips, pissing off quite a few engineers who then dropped FTDI as a future supplier entirely. > Do you also try to install OS-X on a DELL laptop, and claim that > it's Apples fault that your DELL machine don't work? (God knows what > interesting things might happen if you actually try this...) Since Macs have been basic x86 PCs for years, it might even almost work (although I guess Apple probably checks for some hardware signatures and tells you to go buy a Mac on foreign hardware). I'm pretty sure the OS-X installer is not going to try to actively brick your Dell.

Not necessarily incompetence, but probably penny pinching. Adding a second firmware flash and the switch to toggle between primary and secondary and another one to actually allow writing to the firmware flash in the first place ... you can shave a bit off the BOM.

I can understand Elnec's distress over the cloning of their product, but they did themselves no favor by taking the approach described here: "...The manufacturer of the fake BeeProgs stole our logo and intellectual property by manufacturing fake copies of BeeProg programmer. This "product" uses also our software and users of this fake BeeProg are asking for our free technical support. Although the copy of the BeeProg programmer is done well, the manufactures of the fake BeeProg overlooked few details. Result is, the fake BeeProg unit differs from the original, visible for the software. We've used one of these differences - it is not a serial number - and our software could detect this fake hardware. If PG4UW software detects a fake hardware, it shows message "Fake programmer unit detected!" and programmer will no longer work. If you're facing such situation, contact please the vendor, where from you bought the programmer, for full credit return. Or you can take this vendor to court for selling a fake products. We regret, we could not provide any assistance in this case..." In the USA, they would probably end up as the target of legal action, since refusing to do the update is legitimate, but disabling the device is a no-no. It amounts basically to theft of a product from the (unaware) owner--sort of an extra-judicial vigilante killing. This reminds me of early failed floppy-copy-protection schemes. Fortunately, there are solutions to restore functionality to the clone Beeprog. I do not know if the same obtains for the clone Plus. --Chuck --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus From alexandre.tabajara at gmail.com Tue Jun 23 16:58:55 2015 From: alexandre.tabajara at gmail.com (Alexandre Souza) Date: Tue, 23 Jun 2015 18:58:55 -0300 Subject: [RANT] EX-PARROT (Was:False Beeprog.

Certainly, it's an assumption that they're CPUs, but then where are the CPUs? They could be behind the blank panels but it would also be a little odd to completely cover them up like that (no apparent power/reset/boot/run switches/lights). Might be CPU on the bottom portion of the front panels (row of 16/17) and comms as you suggest on the upper portion.

Oh, I agree--and there are procedures to get USCBP to do just that: http://www.cbp.gov/trade/priority-issues/ipr But it's awkward to get it done--and costly.

I'm not familiar with the Beeprog in detail, so I'm just asking here... From what has been said the Beeprog requires a software controller, I take it it's not a standalone device, and people have been using the Elnec software to control the counterfeit hardware. So what exactly does bricked mean here? That, after trying to run it from a new version of Elnec software, it will no longer run with the earlier version of the ELNEC software from before the counterfeits came to ELNEC's attention? As much as a user may be annoyed with that and not endear Elnec to them, it still seems like that would within Elnec's 'rights' (whatever those are here). If it will no longer run with software from the counterfeiter, or software one wrote oneself, then the outrage may be justified. But did the counterfeiter ever produce their own controller software?

Granted they will not > get your business but then again they never had it anyway. Granted, but how does the average purchaser *know* that he has a counterfeit version? Do you read every line of text on every vendor's website before you download software? I don't--I go to the page (I might have gotten there via a search engine, so not have seen any other pages) that I'm interested in and download the software. A simple--"you've got a clone, so we're not doing anything for you" would suffice. But going to the extent of "and we're going make your unit inoperable, such that you'll need to seek out expert advice to get it back to where it was" is not cricket. You are stealing functionality and putting a burden on the unwitting customer to return his unit, counterfeit or not, to functionality. As I mentioned, that return to functionality may involve paying someone with the necessary equipment to do just that. Your quarrel as a vendor is not with the purchaser who may be guiltless--being offered a product at a good price with no indication of its illegitimacy. You've stolen from him. He will probably hate you for a very long time. While he might have jumped at the chance to upgrade to a legitimate unit, he'll avoid any of your products at any cost. It's not just dishonest; it's stupid. --Chuck From nf6x at nf6x.net Tue Jun 23 20:49:34 2015 From: nf6x at nf6x.net (Mark J. Blair) Date: Tue, 23 Jun 2015 18:49:34 -0700 Subject: [RANT]False Beeprog.

The Panasonic "Nickel Metal Hydride Technical Handbook" recommends charging for no more than 10-20 hours, saying: "The overcharging of nickel-metal hydride batteries, even by trickle charging, causes a deterioration in the characteristics of the batteries. To prevent overcharging by trickle charging or any other charging method, the provision of a timer to regulate the total charging time is recommended." Panasonic's "Nickel Cadmium Batteries Technical Handbook," on the other hand, says explicitly that continuous trickle charging for Ni-Cds is a recommended charging method. -- Dave From cclist at sydex.com Tue Jun 23 23:58:28 2015 From: cclist at sydex.com (Chuck Guzis) Date: Tue, 23 Jun 2015 21:58:28 -0700 Subject: Megaprocessor - built from individual transistors In-Reply-To: <20150624043846.GA8177@lonesome.com> References: <8C0DF182C93A4F169B7285AF2FEF296E@workshop> <558979C7.20003@ntlworld.com> <5589B7D4.3060800@btinternet.com> <5589DD85.5080002@sydex.com> <20150624043846.GA8177@lonesome.com> Message-ID: <558A38F4.4070408@sydex.com> On 06/23/2015 09:38 PM, Mark Linimon wrote: > Even the ones that were not spy-approved did that :-) Ain't that the truth! --Chuck From emu at e-bbes.com Wed Jun 24 00:08:40 2015 From: emu at e-bbes.com (emu at e-bbes.com) Date: Wed, 24 Jun 2015 07:08:40 +0200 Subject: organizing a trip to Cuba In-Reply-To: References: <20150623163250.GB21341@beast.freibergnet.de> <558992AC.1080204@sydex.com> Message-ID: <20150624070840.f1zxz69jwu684kos@webmail.opentransfer.com> Zitat von Sean Caron : > I've spent a lot of time researching computer engineering in the Eastern > Bloc ... > ...being somewhat isolated from what was canonical over here, > they also had their share of quite unusual indigenous designs ... a few of > the papers I have read discuss experiments with hybrid analog/digital > computers, ternary logic, and the Elbrus VLIW design would have been fairly > innovative for the time ...

I find a lot of the companies who list ribbons don't purge their databases of even the most ridiculously old products, and they list models. I don't have my printer or manuals at hand, but the printer I referred to that looks like the ones here was about 24" on a side. Mine was effectively a table top unit, but there were ones with a bottom feed, etc. Also a very large one which was full size, 14" and just as high speed might be the one in the photo. It didn't come w/o a full floor cabinet. I acquired both, but sold the larger one to a company doing mailing labels for magazines, and also leased the smaller one to them for a while. Both could turn out 5" post cards at in incredible rate. We had to do a bit of engineering to catch the output properly, as it was over 1000 lpm with just a return address and mailing address. Also I don't recall the Data Products ever scaling as fast by restricting columns. At least our 2230, 2260 and 2290 UC only and 96 character set printers didn't. Got the same speed regardless of the columns on those Data Products printers. They were drum, as were the Data Printers, but apparently the hammer logic vs. the line feed was not coupled as far a speeding up with fewer columns.

I wanted to make clear that not all clones are clones. I have an Elektronika 60 which is something like an 11/03 clone but it isn't a clone. It has a Q-BUS with connecteors like DECs original but with metric pin raster. Boards are bigger and the used chips and the schematics are totally different in most cases.S My memory confused the VAX730 with the VAX750... The machine is a development of it's own conforming some of the DEC Specs so that the original Software can run on that thing (E60). (The console SLU is a quad size board build from only TTL) The same happened with that VAX730 Chip, it was developed from only 10 people following the DEC reference manual. http://www.155la3.ru/k1839.htm http://www.online-translator.com gives halfways readable results from the translation of the web frame from russian to english. ..for PDP11 like processors: http://www.155la3.ru/k1801.htm I have a file with the internal Schematics (!) of the K1801VM2 processor, a PDP11 running w/o MMU at 10Mhz.

Zoom in on the 2nd photo of the model here: http://www.computerhistory.org/revolution/mobile-computing/18/315/1673 Note the mag tape units, the orientation and outline would match your second photo (the double vertical rectangles on the front in the model match those behind the left fellow's head and the right fellow's hand. Flexowriter also present in the model. Another version of the model down the page here: http://www.usarmygermany.com/Sont.htm?http&&&www.usarmygermany.com/Units/ComZ/USAREUR_ComZone.htm Your photos may be quite rare, the MOBIDIC project is often mentioned in computing history but photos of the actual MOBIDIC seem to be hard to come by.

Oh, I know. I'm from Sweden. We had a very big scandal where 5 containers with a VAX-11/782 and peripherials or something like that was found under strange circumstances. When the whole thing started to be investigated suddenly no one seemed to know or own those containers. The system was unclaimed for years, and it became a question of what to do with it, since no one seemed to claim it. I think it was eventually decided that since DEC made it, it was returned to them. The original shipping destination was of course somewhere in Soviet Union. This was in the early 80s... I'm sure someone can find the full story online somewhere. The stuff spy thrillers are made from... :-) Johnny > > The copying was much more like the space race and said a alot about what > silicon processing the USSR had or had access to. > > Rod > > On 24/06/2015 12:40, Johnny Billquist wrote: >> On 2015-06-24 08:45, Holm Tiffe wrote: >>> Johnny Billquist wrote: >>> >>>> Well, unless I'm mistaken, when the Russian VAX-11/730 on a chip came, >>>> DEC had already produced the uVAX II, which is also just a chip, but >>>> much faster than an 11/730, so it's not exactly as if the Russians were >>>> outperforming what DEC was doing...

Looking at the screenshots, though, it's interesting how much I'd obviously forgotten, and the text there makes it clear there's also a lot more I never knew. The main reason I'm interested in the source to Empire is to make my recreation of it behave more like the original. I'm not trying for a total clone - if that's what I were after I'd be looking for a PLATO simulator to run the original on - but something that feels not too unlike it while still being recognizably a little more modern (for example, using finer resolution on the display).

The 0 prefix in the lesson name indicates a ?published lesson? ? which means a frozen copy of the original made by CDC and distributed as part of the PLATO distribution. The original name was ?empire? and it became famous under that name at its original home, University of Illinois PLATO. As for PLATO simulation, there is one, which John mentions (cyber1).

The HP 2767A service manual (02767-90002, available from Bitsavers) is a reprint of the Data Products 2310 service manual. Page 1-17 says: "The printer receives data from the user system and stores up to 20 characters in the buffer memory. [...] A full line of data is printed in four zones, each zone having 20 consecutive print positions. In this manner, the printer's 20 hammer drivers can be time-shared among the 80 print positions." ...and the spec on page 1-5 says the print rate for the 64-character drum is 356 lines per minute for 80 columns, 460 lpm for 60 columns, 650 lpm for 40 columns, and 1110 lpm for 20 columns. I tested a 2767A as a customer of the HP Rockville, MD office in the early 1970s. As I recall, the character set wasn't staggered on the drum, and the hammer force was constant, regardless of glyph area. The result of printing a line of hyphens -- or worse, a line of periods -- was a very loud bang and a neatly perfed page. -- Dave From paulkoning at comcast.net Wed Jun 24 11:40:56 2015 From: paulkoning at comcast.net (Paul Koning) Date: Wed, 24 Jun 2015 12:40:56 -0400 Subject: PLATO Empire source?

Both the layout and tactile feel are truly part of the ?Empire? experience. Aaron Woolfson (at Telswitch) has done that. Proper copies, with USB interface but using the same switches (they still exist) and the correct keycaps. His initial run sold out; I?m not sure if a new one has been created. The original one triggers an OSX bug so you can?t use it on a Mac, but other operating systems handle it fine. paul From wulfman at wulfman.com Wed Jun 24 11:50:39 2015 From: wulfman at wulfman.com (wulfman) Date: Wed, 24 Jun 2015 09:50:39 -0700 Subject: 1990 Era computer room In-Reply-To: References: <10ff88.7e22688c.42bb129a@aol.com>, <20150624043956.GB8177@lonesome.com>, <558A3C98.9070903@jwsss.com> Message-ID: <558ADFDF.8020004@wulfman.com> ahh the memorys i worked at dataproducts from late 1978 to late 1980 they were awesome printers the B series used the 2900 series bit slice building blocks they were speed daemons for their time its too bad that manufacturing in the USA has dropped because of cheap Chinese we may still have great companys like that making things here in the USA On 6/24/2015 9:33 AM, J.

When you fired all the same characters on these printers, however the printer almost seemed like it wanted to move with a 64 character model. It was possible to get it to do that if you studied how to get the right pattern of characters. > "The printer receives data from the user system and stores up to 20 > characters in the buffer memory.

They were very good printers. Printronix moved to across the street from where I worked on Myford in Tustin some years after that and made a good run, but I never used Printronix after the P300 and P600. Next ones we used were CI-300's, 600's and 900's because we got an OEM deal thru them, and the above mentioned Data Products band printers for applications requiring such character sets, rather than the dot matrix.

The only Flexowriters I?ve run into are those used for Algol programming at TU Eindhoven. They were better than many teletypes ? upper and lower case, for one, and first class reliability. But certainly nowhere enough characters for typesetting, not unless you used markup codes for things like italics (at which point an ASR33 would be almost as good). Old style paper tape typesetting tended to use specialized machines. Monotype uses oddball very wide tape, and Tape Operated Linotype uses, I think, 6 track paper tape but the perforating keyboard machines had specialized features in them to track the line width. paul From alexandre.tabajara at gmail.com Wed Jun 24 16:13:08 2015 From: alexandre.tabajara at gmail.com (Alexandre Souza) Date: Wed, 24 Jun 2015 18:13:08 -0300 Subject: Printer ribbons [Was: Re: 1990 Era computer room] References: <10ff88.7e22688c.42bb129a@aol.com> <5589E0EE.5090904@jwsss.com> <20150624043956.GB8177@lonesome.com> <558A3C98.9070903@jwsss.com> <20150624081959.GA17402@Update.UU.SE> Message-ID: Get a printer ribbon from another printer, take the ribbon from the cartridge and put it on the cartridge of your printer.

My 8/e had the reed switched based one which had broken reeds and a weak magnet.I replaced the reeds with small one found on ebay and also the magnet to get it working.It has a sloppy feel to it. My 8/m has a mechanical switch. It has a much nicer feel than the reed based one.Probably the different way the panels are marked is because of these two ways of makinga rotary switch. I have no idea why DEC made their own switch out of the reeds. Seems like it would cost more than a standard switch so they probably had a reason. Possibly they thought it would not wear as much with thereeds having millions of operations rating. -Bob From v.slyngstad at frontier.com Wed Jun 24 16:39:08 2015 From: v.slyngstad at frontier.com (Vincent Slyngstad) Date: Wed, 24 Jun 2015 14:39:08 -0700 Subject: Front Panel Update A and B panels In-Reply-To: <1685136279.621536.1435181320136.JavaMail.yahoo@mail.yahoo.com> References: <1685136279.621536.1435181320136.JavaMail.yahoo@mail.yahoo.com> Message-ID: <89091F4D6F3545E6ADF75E05F8081966@Vincew7> From: Bob Rosenbloom: Wednesday, June 24, 2015 2:28 PM > I have no idea why DEC made their own switch out of the reeds.

I'm not sure they made their own. There's "Angley" or some such written around the corner from the DEC part number on the bottom plate. (Partially obscured by the mounting screw.) I took that to be a maker's mark, though I didn't find any surviving reference to them online.

Message-ID: Hello, I recently acquired a Persci 2142 dual disk drive with two S-100 controller cards. The 2142 is a Persci slim-line case that fits the internal Persci 299 drives but also included were to Persci S-100 cards. The only thing that makes sense is that one or both of these are the Persci 1170 controller card (set) but I have not been able to find a picture of such a card anywhere. There is an 1170 card picture at the Computer History Museum but it suspiciously looks like a Vector S-100 prototype board with components on it (and not the right amount compare to my cards). That page is here: http://www.computerhistory.org/collections/catalog/102712583 I have pictures in my latest post of the front and back of both cards along with the Persci 299 drive mechanism and the complete 2142 unit. If anyone knows what a Persci 1170 controller looks like, I'd love to know if that's what I have. Is it both cards? I am assuming so because there's a marketing brochure out there with a description of the 1170 controller and the Z80 CPU, as described, is on the second card (not the main card) as is the memory. Pictures of what I have are here: http://vintagecomputer.ca/persci-drive-is-a-299-what-are-the-controller-boards/ I can try to read the EPROMS on the second board (they are B2716s) but the first board has a 2708 and I've nothing that will read it. Maybe that will give a clue? I would assume that's where Persci DOS is? I will be taking the 299 drive mechanism apart and refurbishing this drive as I did the Persci 270 in my Processor Technology Helios II (big thanks to Martin Eberhard for his awesome guide and his help!). Hopefully it's close enough to the 299 that the guide will still be useful. I have yet to check if the glass gauge is intact in this drive or all of this will be for nothing. I'll do that when I take it apart. Should be a fun project. If you have any info, please let me know. It would be much appreciated.

With 3d printers, it shouldn't be too much of a problem to make your own paddles at whatever scale is required. The only catch I perceive is which switch to use.

Yup, about five years ago, I gave away mine on the Vintage Computer forum. It had very little mileage on it, mostly because of the mess.

That may not be advisable, given the continuous constant-current trickle charger in the CPU power supply. The Panasonic "Nickel Metal Hydride Technical Handbook" recommends charging for no more than 10-20 hours, saying: "The overcharging of nickel-metal hydride batteries, even by trickle charging, causes a deterioration in the characteristics of the batteries. To prevent overcharging by trickle charging or any other charging method, the provision of a timer to regulate the total charging time is recommended."

I want to shrink the machine and minimize any need to reengineer the backplane. By the way, can the backplane of a straight-eight be realized as a PCB? Of course. The only reason a PCB backplane would be an issue is if there are signal integrity concerns, but at DEC speeds that?s not going to be a problem. Especially if what you?re aiming to replace is wire wrap which is in general worse at signal integrity than PCB. Now if you were looking to replace the chassis wiring of a 6600 with a PCB, that would be a different matter, then you?d want to be a bit more cautious. Even then it?s clearly doable, if you use transmission line design on the PCB signals. paul From pontus at Update.UU.SE Thu Jun 25 08:39:05 2015 From: pontus at Update.UU.SE (Pontus Pihlgren) Date: Thu, 25 Jun 2015 15:39:05 +0200 Subject: Megaprocessor - built from individual transistors In-Reply-To: <05966252-6300-46FD-A7C1-55E6B2639025@661.org> References: <8C0DF182C93A4F169B7285AF2FEF296E@workshop> <558979C7.20003@ntlworld.com> <201506231620.t5NGKSbB076352@ultimate.com> <20150624082756.GC17402@Update.UU.SE> <05966252-6300-46FD-A7C1-55E6B2639025@661.org> Message-ID: <20150625133905.GE15395@Update.UU.SE> On Thu, Jun 25, 2015 at 04:16:03AM -0700, David Griffith wrote: > > I don't think thatt making the flip-chips double-sided will be > desirable.

Replicating that > component without that will suck. I've not chosen that restriction and would not mind rerouting the backplane if it means 1. that I can shrink the design and 2. if it means I can fit it on a multilayer PCB of suitable size. Now, I've looked at the backplane of a PDP-12 and it looks to be 4 or 5 levels deep at the most and fairly "roomy". So, with my limited experience it doesn't seem impossible to recreate in a 4 layer PCB. I'm not sure what would be a suitable edge connector though, that would probably dictate the size of the flip chips more than anything. Please correct me if I'm talking complete bulls**t. This is all new to me. /P From jnc at mercury.lcs.mit.edu Thu Jun 25 08:45:35 2015 From: jnc at mercury.lcs.mit.edu (Noel Chiappa) Date: Thu, 25 Jun 2015 09:45:35 -0400 (EDT) Subject: UNIBUS extension card/cable sets Message-ID: <20150625134535.EA08418C09A@mercury.lcs.mit.edu> > From: Alan Perry > FYI, in my 750, the UNIBUS expansion has a L0010 in the main cabinet > and a M9014 in the expansion cabinet. > From: tony duell > If it's any help I pulled an M9014 out of the Unibus Out slot of my > 11/730. There's currently an M9302 in there. Very interesting! Thanks for the data. This seems to indicate that the M9014 could function as either end of the cable. I was wondering if maybe the M9015 was an M9014 with termination resistors, or something (the way the QBUS versions come with and with termination), so I tried to find a picture of one, but... I can't even find a picture! Has anyone even seen an M9015? >> I see 'three' different kinds of 'UNIBUS to cables' cards listed: >> M9014 UNIBUS to 3 H854s >> M9015 3 H854s to UNIBUS >> M9031 UNIBUS to 3 3M cables for 11/74 >> M9042 UNIBUS to 3 H854, Dual So I have compared an M9014 and an M9042; the former is a 'normal' height dual module, the latter is a 'short' dual module. I suspect that they have the same pinout on the Berg headers; I tried a couple of UNIBUS signals, and they led to the same pin on the Bergs on the two different units. If and when I get energetic I will make a complete pinout list for the two units (I haven't been able to find any documentation on any of them online). Some day I'll even try joining a BA11 to an -11 with a pair of M9014's, and see if it does indeed work. Also, does anyone out there with an 11/70 know what the M9031 is used for?

Somewhere I have the expansion box that went with this VAX. The thing is that I moved some items into a storage unit for the house move and haven't moved them back again. I suspect the expansion box was amongst them. When I get a circular tuit of a suitable type I will take a look at what is in there. The M9014 is just connectors. There are 3 40 pin Berg headers, one row of each appears to be ground (or at least they're all joined together and if they go somewhere other than ground I will be very surprised) That leaves 60 pins for the unibus signals. Of course power will not be carried. > I was wondering if maybe the M9015 was an M9014 with termination resistors, > or something (the way the QBUS versions come with and with termination), so I would be very surprised. Unibus is normally terminated at the ends and not in the middle. I guess the 11/730 terminates the 'start', you put an M9302 in the 'end' I think I did read somewhere you could use a BC11A cable with the 11/730 (this does not surprise me), so that would not have extra termination. -tony From jnc at mercury.lcs.mit.edu Thu Jun 25 11:02:53 2015 From: jnc at mercury.lcs.mit.edu (Noel Chiappa) Date: Thu, 25 Jun 2015 12:02:53 -0400 (EDT) Subject: Transmission lines Was: UNIBUS extension card/cable sets Message-ID: <20150625160253.D4E1318C0A4@mercury.lcs.mit.edu> > From: John Wilson > I chose the digital version of EE as my major precisely because I knew > I'd flunk Fields and Waves.

The way I think about them is to model them as pipes, and the signal as a sound (single pulse) sent down the pipe. Proper termination is like a piece of cotton at the end of the pipe, it sucks up the sound and you don't get a reflection. If you just cap off the end of the pipe (i.e. no termination), the sound bounces, and you get an echo. So if you have a small un-terminated branch, part of the pulse bounces off the end, and comes back out, and then propogates both ways, so the original pulse gets a messy trailer tacked on the back of it.

I've laid out a few of DEC's backplanes as PCBs before, mostly for the later designs that use both sides of the edge connectors. They tend to require about 4 signal layers. It can be helpful to bus power separately (using wire much as was originally done), and to route on the diagonal, as the funky sockets have larger chaseways in the diagonal directions. Also, the device is relatively high current. Some of my earlier attempts used trace widths that, in retrospect, weren't wide enough (especially power traces), trying to keep the number of layers down. I can't particularly recommend the original backplane form factor. They are all based on a 1/8 inch grid instead of the industry standard 0.1 inch, and not at all easy to find or inexpensive these days.

To my mind, the obvious choice for a new edge connector would be 0.1" headers and sockets. They are easy to find and produced by the millions, which means they are also relatively affordable. > Please correct me if I'm talking complete bulls**t. This is all > new to me. The only other concern I've had during my thought experiments along this line related again to the current/power involved. The device is likely to become difficult to cool if you achieve a 4X volume reduction. Oh, and I guess the nightmare of soldering many thousands of surface mount discretes and transistors to manufacture such a thing.

Those ?bounces? occur at any irregularity, and in fact you can locate impedance fluctuations by the echoes they produce; this is called TDR (time domain reflectometry). I still have a photo copied out of the 1980s magazine RSTS Professional, which claimed to show how to convert thick to thin Ethernet. The simple answer is ?with a coax connector adapter? since both are 50 ohm coax. The article instead used a thinwire T connector, with the terminator still on it. As Tony points out, terminators go at the end, not the middle (that?s what the word means). So that configuration would be somewhere between marginal and broken. paul From jnc at mercury.lcs.mit.edu Thu Jun 25 12:02:30 2015 From: jnc at mercury.lcs.mit.edu (Noel Chiappa) Date: Thu, 25 Jun 2015 13:02:30 -0400 (EDT) Subject: UNIBUS extension card/cable sets Message-ID: <20150625170230.5168E18C0A4@mercury.lcs.mit.edu> > From: tony duell > There are 3 40 pin Berg headers, one row of each appears to be ground Ah, hadn't noticed that! But then again, I hadn't looked at them closely yet! :-) Yes, they do connect to ground - all the UNIBUS ground pins are ganged together, and connected to the A-row Berg pins on all 3 connectors. So every other wire on the 40-conductor flat cables should be ground - that's even better than the classic BC11A, where almost every other line is, from what I can see, simply left floating (which is better than nothing, but not as good as grounding them, is my understanding). >> I was wondering if maybe the M9015 was an M9014 with termination >> resistors, or something (the way the QBUS versions come with and with >> termination) > I would be very surprised. Unibus is normally terminated at the ends > and not in the middle. Right, but the very similar QBUS does have terminations (of a sort - the rules for when you need terminations on QBUS extensions are so complex that I don't really grok them yet) 'in the middle', so... I just couldn't find out _anything_ about M9015's, so I was just guessing in the dark. Real data gratefully received. > From: John Wilson > I was kind of assuming that there's some impedance-matching (etc.) > problem with using ribbon cables for more than one hop. Hmm. Well, I dunno; that may be beyond my (minimal :-) level of analog expertise. I would have assumed that it's the _change_ from one impedance level to another that's the issue (you can get a reflection off the junction), so whether one's using long or short cables between a pair of M9014's, it shouldn't be _that_ big a deal (modulo propagation delays, which _are_ an issue with length). Perhaps someone else can opine? But I hope we can do fairly long runs with the 40-conductor (aka BC05L-xx), that could save us when we run out of BC11A's, if that strange Flexprint flat white cable the BC11A uses is no longer available. Noel PS: From what I can see so far (done half the pins), the M9014 and M9042 do have an identical pinout on the Berg connectors.

That doesn?t seem likely. While DEC engineers on average didn?t understand transmission lines as well as, say, Cray engineers, the definition of ?termination? is something that you learn in EE 101 and are unlikely to forget. paul From ard at p850ug1.demon.co.uk Thu Jun 25 12:41:17 2015 From: ard at p850ug1.demon.co.uk (tony duell) Date: Thu, 25 Jun 2015 17:41:17 +0000 Subject: UNIBUS extension card/cable sets In-Reply-To: <20150625170230.5168E18C0A4@mercury.lcs.mit.edu> References: <20150625170230.5168E18C0A4@mercury.lcs.mit.edu> Message-ID: [M9014] [One row on each Berg is ground] > Ah, hadn't noticed that!

I am surprised. DEC didn't waste copper like that. It's been a long time since I worked on a BC11A, but I thought alternate wires were grounded. Maybe a track right along the edge of the PCB where the cable comes off (so you can't see it). I will check. > Right, but the very similar QBUS does have terminations (of a sort - the > rules for when you need terminations on QBUS extensions are so complex that I > don't really grok them yet) 'in the middle', so... I never really understood the Qbus rules either. The ones I saw make very little electrical sense (unlike Unibus, which is designed as a transmission line). I don't think I've ever taken Qbus outside one backplane, as a result just about anything will work. On Unibus too, you can generally get away with no terminator at the far end if you are in one backplane, or even one mouting box. Can be useful for testing... > Hmm.

Perhaps someone else can opine? Well, Unibus is terminated into 180 Ohms and 390 Ohms, isn't it? The thevenin equivalent is thus around 123 Ohms. Most ribbon cables have a characteristic impedance when used with alternate wires grounded of around 100 Ohms (I seem to remember that is certainly right for the twist-n-flat ones). That's a small mismatch, but I don't think it is going to cause big problems. -tony From bqt at update.uu.se Thu Jun 25 12:49:13 2015 From: bqt at update.uu.se (Johnny Billquist) Date: Thu, 25 Jun 2015 19:49:13 +0200 Subject: organizing a trip to Cuba In-Reply-To: References: <20150623163250.GB21341@beast.freibergnet.de> <99569D13-C04C-49FF-AC55-1BCCC6396169@nf6x.net> <558A14E3.7000402@update.uu.se> <20150624064513.GB83163@beast.freibergnet.de> <558A972E.9020202@update.uu.se> <558A9AE5.30000@btinternet.com> <558AA03C.5040708@update.uu.se> Message-ID: <558C3F19.8090803@update.uu.se> On 2015-06-25 13:31, Liam Proven wrote: > On 24 June 2015 at 14:19, Johnny Billquist wrote: >> Oh, I know.

Some interesting information on that page. But anyway, no, the smuggling story in that article is not the one I was referring to. That story is about some Swedish computers for ATC (also usable for military purposes obviously) which contained some American components, for which Sweden did not have an export license, so they somehow got to the SU without permission, which was later revealed, and was not a nice story, since the Swedish government was involved. Search for "containeraff?ren" in Google (unfortunately I only manage to find Swedish texts about it, but Google translate is your friend). In short, a private businessman in Sweden was involved a the shipping of a VAX-11/782 and peripherials via South Africa and Sweden (maybe Switzerland was also involved). It was caught by the Swedish customs, and the stuff never reached the SU. I guess that sortof repaired the damage of the previous "Saab-aff?ren" story in the eyes of the USA...

I really do fail to see how you can possibly understand or design digital systems without understanding analogue electronics, in particular transmission lines. FWIW the Motorola ECL databooks were pretty good at giving an introduction to this, simpy because with ECL you have to design just about every interconnection as a transmission line. Do it right and the design works, and unlike some other logic families where you hope for the best with the interconnections, ECL stays working. > I still have a photo copied out of the 1980s magazine RSTS Professional, which claimed to show how to convert > thick to thin Ethernet.

I agree with your sentiments, _but_ all I know is that if you look at, e.g. the 1982 'microcomputers and memories' handbook, pg. 251, you'l see a three-backplane system, with terminations at the start _and_ end of the first backplane (and also at the end of the third backplane). I've seen other similar diagrams elsewhere, that's merely the first one I ran across in a quick search for this post. Like I said, I cheerfully admit that I don't really fully understand what's going on there in the analog domain, but I've seen this in more than one place in the DEC QBUS multi-backplane configuration instructions.

I see a slight difference in the input current spec of the receiver part of the transceiver. 250 uA instead of 25 uA. That makes some small amount of sense given the smaller station count. > >> article instead used a thinwire T connector, with the terminator still on it.

Good point, collisions are not reflections, though reflections will be interpreted as collisions. Your comment about measuring voltages reminds me of a network monitoring device DEC built, and almost turned into a product. This was mainly for thickwire, though it would work on thinwire too. The intent was to map stations by their physical position on the cable. The approach was to put voltage measuring devices at both terminators, and record the observed voltage levels for packets from a given MAC address. The voltage ratios at the two ends would tell you where the station is, provided the coax is reasonably uniform. And the ranking of those ratios would pretty accurately show you the station order even if the cable isn?t all that uniform. I?m not sure why this wasn?t shipped. Perhaps it was around the time that structured wiring and star-based wiring with lots of repeaters started to come out, displacing the long bus topologies of the original Ethernet. paul From paulkoning at comcast.net Thu Jun 25 13:06:46 2015 From: paulkoning at comcast.net (Paul Koning) Date: Thu, 25 Jun 2015 14:06:46 -0400 Subject: UNIBUS extension card/cable sets In-Reply-To: <20150625180129.414CE18C0A4@mercury.lcs.mit.edu> References: <20150625180129.414CE18C0A4@mercury.lcs.mit.edu> Message-ID: <09DBB9C6-CD22-43BD-97B8-CB0FA75BCF17@comcast.net> > On Jun 25, 2015, at 2:01 PM, Noel Chiappa wrote: > >> From: Paul Koning > >>> Right, but the very similar QBUS does have terminations (of a sort - >>> the rules for when you need terminations on QBUS extensions are so >>> complex that I don't really grok them yet) 'in the middle' > >> That doesn't seem likely. ... the definition of 'termination' is >> something that you learn in EE 101 and are unlikely to forget. > > I agree with your sentiments, _but_ all I know is that if you look at, > e.g. the 1982 'microcomputers and memories' handbook, pg. 251, you'l see a > three-backplane system, with terminations at the start _and_ end of the first > backplane (and also at the end of the third backplane). What?s between the backplanes? If it?s a repeater, that would be correct (because you have two separate transmission lines). If it?s a cable, then this is wrong. But as Tony said, it might be that it?s not so wrong that things break, thanks to the small scale and slow speed of Qbus. paul From alexandre.tabajara at gmail.com Thu Jun 25 17:12:57 2015 From: alexandre.tabajara at gmail.com (Alexandre Souza) Date: Thu, 25 Jun 2015 19:12:57 -0300 Subject: Imaging TRS-80/III single-sided disks Message-ID: <3A68AC30E06343C3ADE682259EE1AC03@deskjara> Dear sirs, Imagedisk is my savior, and I image all kind of disks I know with it :) But now I got a pair of TRS-80 model III single-sided disks.

How do I > image it using imagedisk? Same as every other disk that you have imaged. However tell Imagedisk that you only want side A. That shouldn't be a big deal, but many people with single sided drives reFORMATed, without erasing what was on the second side. Therefore, it is possible, if they were using used disks, that side B might still contain side B from some previous use, such as PC or Apple. And, some people using single sided drives punched extra holes in the jacket to be able to flip the disk over ("FLIPPY disks") to use the other side as if it were another disk. so, if you see an extra write enable notch on the wrong edge of the disk, and/or amateur holes made to make index hole access symmetrical, then the disk may have been flipped over and written with a single sided drive. "Berkely MicroComputer Flip-Jig" was the best jig ever made for marking diskettes for making flippies. The model 3 TRSDOS was 256 bytes per sector, with 18 sectors per track. HOWEVER, besides TRSDOS, there were other operating systems that could be run on it, and some of the CP/M conversions used other sector sizes. > Can I use a double-sided floppy drive to image it? YES. Although there have existed some drives where SS and DS were actually incompatible, such as the difference in index hole placements on 8", Side A of a Single Sided 5.25" disk is the same as Side A of a DS disk. 360K drives will work just fine. NOTE: If you use a 1.2M drive, then you will encounter exactly the same issues as when you use the 1.2M on a 360K PC disk. MORE IMPORTANT NOTE: TRS-80 used a Western Digital FDC; IBM uses NEC. (TYPE of FDC, disunirregardless of BRAND used) TRS-80 starts the first sectors of the tracks earlier on the track than IBM. You will sometimes encounter TRS-80 disks on which the first sector of each track can't be found/read by the PC! That can actually be worked around fairly easily. If you interrupt the index signal, then a disk can still be read or written, but can not be formatted (and any errors will no longer be properly understood by the BIOS). You can interrupt the signal by making a special floppy cable without that wire, or with a toggle switch on that wire, or maybe putting a tiny piece of electrical tape on the card edge, so that that pin of the cable doesn't connect. Will you remember to set things right afterwards? Or, you could clip the wire of the index sensor (in a reversible way!!!). OR, you can try just putting a small piece of opague tape (such as a write protect tab!) over the index hole access hole of the disk jacket. On some drives that are too smart for their own good, such as the otherwise nice Teac 55, that will be misinterpreted as drive not ready! But it works great on the original full height Tandons used by TRS-80 and by PC/5150. Do not let your tape fall off into the drive. Sometimes it may work to slow down the motor of the drive, and run it at too slow a speed. > Or do I need to put the single-sided drive on my PC? Please, help! :) NO. In fact 160K/180K PC drives (the SS version used before DOs 2.0 provided double sided capability) were often the SAME BRAND, SAME MODEL drives as TRS-80 model 3. The 360K DS drives (since DOS 2.0) were still the same, with the addition of a second side. Later, IBM switched to other brands and models of drives, such as "half height", but they remained completely compatible. WARNING: If you DO put the TRS-80 drive into a PC, you will need to change some jumpers! The original normal/standard configuration for such drives ("SA400 interface") uses pin 10 for drive select of drive A, pin 12 for drive select of drive B, pin 14 for drive select of drive C, and did not provide for a fourth drive. Radio Shack did not consider their customers, NOR THEIR STORE PERSONNEL, to be competent to change jumpers of the drives for TRS-80 model 1. So, they put in ALL of those jumpers, including using another "unused" pin for drive D (which later drives used for SIDE SELECT!, and then they removed the pins in the connector cable for each position so that each drive connector of the cable only had one drive select pin connected. Then, the drive would automagically be whichever drive that position of the cable was for. Therefore, connecting a TRS-80 drive to a PC requires changing the jumpers. IBM did not consider their customers, NOR THEIR STORE PERSONNEL, to be competent to change jumpers of the drives for PC/5150. So, they jumpered every drive as if it were drive B (pin 12), and then they put a twist in the cable so that pin 10 of the FDC board connected to pin 12 of drive A, and pin 12 of the FDC board connected to pin 12 of drive B. That twisted cable also made changes in how the motor was turned on. Therefore, connecting a TRS-80 drive to a PC requires changing the jumpers. Both TRS-80 and PC/5150 have provision for FOUR drives, but that's not your current problem (except for the TRS-80 model 1 having screwed around with what would later become SIDE SELECT) -- Grumpy Ol' Fred cisin at xenosoft.com From v.slyngstad at frontier.com Thu Jun 25 19:15:55 2015 From: v.slyngstad at frontier.com (Vincent Slyngstad) Date: Thu, 25 Jun 2015 17:15:55 -0700 Subject: Megaprocessor - built from individual transistors In-Reply-To: References: <8C0DF182C93A4F169B7285AF2FEF296E@workshop> <558979C7.20003@ntlworld.com> <201506231620.t5NGKSbB076352@ultimate.com> <20150624082756.GC17402@Update.UU.SE> <05966252-6300-46FD-A7C1-55E6B2639025@661.org> Message-ID: From: Doug Ingraham: Thursday, June 25, 2015 4:10 PM > On Thu, Jun 25, 2015 at 10:22 AM, Vincent Slyngstad wrote: >> The only other concern I've had during my thought experiments >> along this line related again to the current/power involved.

I had assumed, since the subject contains "built from individual transistors", that something akin to the original straight-8 circuits was what was being discussed. Straight 8 signals typically run 8 mA when low and 10 mA when high, and that's from the -15V supply, per signal. I estimate that's a few hundred watts for the whole thing. Reducing the supply voltage to -5V would presumably cut the power (and hence the heat) to a third, by eliminating most of the waste heat from all the pull-downs. > The Straight 8 logic uses pulses for some things instead of levels making > it not really compatible with more modern logic.

I completely agree, at least if you're actually going to use the darn thing a few hours at a time. Some models of the PDP-11 did use much smaller (still available) switches, but fitted them with honking paddles to make them more comfortable to use. Vince From cisin at xenosoft.com Thu Jun 25 19:19:08 2015 From: cisin at xenosoft.com (Fred Cisin) Date: Thu, 25 Jun 2015 17:19:08 -0700 (PDT) Subject: Imaging TRS-80/III single-sided disks In-Reply-To: References: <3A68AC30E06343C3ADE682259EE1AC03@deskjara> Message-ID: A few more gotchas to be aware of: Some of the operating systems on TRS-80 started the sector numbering at 0. Therefore, depending on which operating systems were used, you could have sectors numbered 0 - 17 , or 1 - 18. That can be confusing if your PC can't read the first sector, but tells you that it successfully read sector #1. Model 1 TRS-DOS is SINGLE DENSITY. IMD can handle that IFF the FDC in your PC is one of the ones that supports FM/SD. NOTE: some/many? TRS-80 users installed additional hardware for double density, but the OS might still require FM/SD for track 0. Disks written on a stock model 3 for use in a model 1 are not quite the same format as model 1 disks. Model 1 TRS-DOS uses some "NON-STANDARD" DAMs (Data Address Marks). I don't know how to read those with PC FDC. But, they can be read with Catweasel, OptionBoard, or other "flux transition" boards. Or design and build a PC FDC board with a 1771 WD FDC and a WD 179x FDC just to be able to handle disks with NEC/WD incompatabilities - NOTE: that disk controller should ALSO have an NEC FDC, or you won't be able to have full PC compatability. Model 1 TRS-80 has 35 tracks. They started off using the Shugart SA-400 floppy drive, which is 35 track. I think that most/all? of their later drives could do a full 40 tracks, BUT don't count on the software supporting that. Expect 35 tracks for TRS-DOS, although most/all? of the after-market operating systems supported 40 track, and some supported double sided drives ("Gee, didn't expect THAT!"), and some users even used 80 cylinder drives, for 720K capacity. Yes, there were also hardware mods for TRS-80 to use 8" disks. Yes, you can put 3", 3.25", or 3.5" drives on a TRS-80. Not all TRS-80 diskettes were of the highest quality. Be prepared to clean the heads of your drive after you finish, and maybe periodically part way through. Some TRS-80 users considered Wabash to be "premium" diskettes. -- Grumpy Ol' Fred cisin at xenosoft.com From rollerton at gmail.com Thu Jun 25 23:47:52 2015 From: rollerton at gmail.com (Robert Ollerton) Date: Thu, 25 Jun 2015 21:47:52 -0700 Subject: Northtop Flying Wing, inflight computing / was Re: XH558 - was Re: using new technology etc In-Reply-To: <3A3ACF56-71EC-460B-B1F4-AA739AE37244@cs.ubc.ca> References: <1186701935.850249.1434725906442.JavaMail.root@md02.topaz.synacor.com> <3A3ACF56-71EC-460B-B1F4-AA739AE37244@cs.ubc.ca> Message-ID: >From memory, so please forgive a mistake or two: The TB-49 Wings would Yaw (side to side motion) while in flight, sometimes just enough to make the crew seasick, sometimes enough to be dangerous when in formation with other aircraft and always unable to stay on track to be a useful bomber.

Message-ID: Hi, All, I just picked up a couple of AT&T terminals, a 730+ and a 5620 "Blit" terminal. The 730+ powers on, passes self-test and probably would work great if I had a keyboard for it. The 5620 lights the CRT but doesn't appear to work outside of presenting a huge green dot the size of the raster. It also lacks a keyboard. I have hopes that it's something simple like wonky internal connectors that need to be reseated (vs bad components). I read on one of the several FAQs that I can use an AT&T 4410 terminal keyboard with the 730+. The box has an 8p8c jack. Additionally, from the same source, I got a 3B1/7300 keyboard and mouse. It happens to have an 8-pin 0.1" female connector in a barbed-lock housing. Outside of the connector, the key layout is superficially the same as a picture I saw of a 730+/4410 keyboard. What I'm curious about is if they are electrically compatible - i.e., could one make an 8p8c->2x4 pin header pin swabber and have the 3B1 keyboard work on the 730+? I won't shocked if they are entirely different, but there are enough superficial similarities that I'm minded to at least ask. I've found the trove of old Blit apps, etc. and see how tortuous the path is to get layers working, etc., but for now, I've got a couple old terminals that are entirely unlike any of the DEC terminals I have, so that by itself is cool. Thanks for any deep knowledge of these guys that isn't already covered on the FAQs. -ethan From santo.nucifora at gmail.com Fri Jun 26 06:11:33 2015 From: santo.nucifora at gmail.com (Santo Nucifora) Date: Fri, 26 Jun 2015 07:11:33 -0400 Subject: Persci 299 with unknown Persci dual S-100 cards?

What's the number for the regular flat? (I have a ton of the latter, but none of the twisted kind. And speaking of the twisted kind, I've always wondered what kind of machine they used to produce it - the mind reels!)

Not a lot of help, but there's a brochure for the 1070 and 1170 controllers here: http://maben.homeip.net/static/S100/persci/brochure/Persci%201070%201170%20Controllers.pdf The one picture in the brochure looks like it is of the 1070 though, so no pic of the 1170; it also doesn't mention it being a double-board set.

Yes, a famous story in the aviation world. Somebody had a lot of class. The book has a picture of Jack with the B-2 design team. {Hope I got the attribution right here: I didn't get the intermediate messages, so I'm picking this out of a later reply.} >> On 2015-06-19 3:05 PM, geneb wrote: >> it's my understanding that the program was cancelled because at the >> time, the USAAF (USAF?) mandated stall testing as part of their >> development programs.

See pp. 160-161; they did deliberately stall a YB-49 as part of the flight test program; it was pretty benign unless the CG was way aft, in which case it became a handful. The Air Force did lose one during flight testing, it is thought perhaps as the result of a spin; it is further thought that perhaps Northrop's guidance on how to handle spins in this very unusual flying device wasn't given to the test pilots - one of whom was Glen Edwards, who the Edwards AFB is named after. The book isn't clear on why the wings were dropped; it seems to have been a combination of DoD budget limitations, cost over-runs in the wing program, the loss of the two YB-49 prototypes in accidents, etc. Noel From ard at p850ug1.demon.co.uk Fri Jun 26 12:59:30 2015 From: ard at p850ug1.demon.co.uk (tony duell) Date: Fri, 26 Jun 2015 17:59:30 +0000 Subject: UNIBUS extension card/cable sets In-Reply-To: <20150626125735.E6A0318C0C5@mercury.lcs.mit.edu> References: <20150626125735.E6A0318C0C5@mercury.lcs.mit.edu> Message-ID: [BC11A cable] > You're right, the alternates are grounded (ohmmeter shows it).

Generally yes. I think you'll get a reflection at one end of the mismatched cable and a similar, but inverted, one at the other end. The length of the mismatched bit will presuambly affect the time between the reflections but not how big they are. -tony From hilpert at cs.ubc.ca Fri Jun 26 13:08:07 2015 From: hilpert at cs.ubc.ca (Brent Hilpert) Date: Fri, 26 Jun 2015 11:08:07 -0700 Subject: Northtop Flying Wing, inflight computing In-Reply-To: <20150626174406.CF48918C0D0@mercury.lcs.mit.edu> References: <20150626174406.CF48918C0D0@mercury.lcs.mit.edu> Message-ID: On 2015-Jun-26, at 10:44 AM, Noel Chiappa wrote: >> On 2015-06-26 12:47 AM, Robert Ollerton wrote: > .. >> Much later, Jack was given a vip tour of the secret B2 factory and >> presented with a model of the design in Lancaster CA before his death. > > Yes, a famous story in the aviation world.

I was looking for that doc a couple days ago for this discussion but didn't find it, and instead found something saying it was because the competition had more effective insiders in Washington. So who knows without original refs/research. Did hear the story of JN being shown the B2 before release, too.

The local Vulcan will be open for visitors and cockpit tours all day. Not sure about the "unique" bit. XH558 is doing a tour of the country this weekend and flying over all the Vulcans around the country. I am going to Newark Air Museum tomorrow, where my dad is a volunteer, specifically for this event. They have a Vulcan there, which I believe has donated parts to XH558, as I am sure have others around the country.

It builds on much of what has already been said. Termination has been covered by various contributors - termination reduces (but may not completely eliminate) reflections. Reflections in a single segment setup (two boxes, one cable) are relatively simple to cope with in a setup from the Qbus era where things aren't particularly fast. In a three box (two cable) setup my recollection is that the configuration rules require the cables to be of significantly different lengths, and the reason for this is to ensure that the two sets of reflections are timed signifcantly differently and canot make Bad Things happen by arriving at the same time as each other. Consider the middle box (of 3) is driving a bus transition. Signals will propagate from the middle box to each of the ends. When the moving rope er sorry voltage transition reaches the end of the cable, it will be reflected to some extent. If the cable segments are both the same length(ish), the reflections will come back to the middle box at round about the same time, superimpose on each other, and potentially cause confusion. (Does that sound plausible?) If the cable segments are of significantly different lengths then the reflections will arrive back at the middle at significantly different times and the reflections will be more manageable - less risk of Bad Things happening when they superpose. Or something along those lines. Anyway, hopefully the "different cable lengths so the reflection timings are different" will ring a few bells even if it's not actually right.

More precisely: terminating a transmission line in its characteristic impedance eliminates the reflection. Terminating it with something that differs from the characteristic impedance will produce a reflection whose magnitude and phase depends on the mismatch. Open and short are extreme examples of mismatches, but any mismatch will produce a reflection. paul From jws at jwsss.com Fri Jun 26 16:45:29 2015 From: jws at jwsss.com (jwsmobile) Date: Fri, 26 Jun 2015 14:45:29 -0700 Subject: Austin Goodwill computer works In-Reply-To: References: <558DA0EA.7040801@jwsss.com> Message-ID: <558DC7F9.8040808@jwsss.com> That is pretty sad to hear.

Message-ID: We're just about at the two-month point to the Vintage Computer Festival Midwest, so now we need to get people their tables and speaking slots. If you need one or both of those, there's a fancy(?) new form for you to fill out here: http://vcfmw.org/signup.html If you already talked to/emailed me about a table, please take a moment to fill out the form anyway. This will be a huge help in getting all of our info in one place. If you're normally on the ECCC/Commodore side, please use this form also. VCF is handling reservations for both sides of the show this year. If I don't hear from you via this form, it may be difficult or impossible to place you at the show. We have a new venue this year and (we hope) much greater attendance. This equals a less predictable room layout. Thank you and we'll see you in August! -j Some answers to recent FAQs: - Speaking topics are pretty flexible - we have generally had mostly product/software announcements and demos in the past and we'd like to diversify a bit (while still including those, of course.) Your restoration saga, tales from the computer revolution, something you're an expert on/at, personal experience in early industry or hobbyist clubs, how you're inspiring the next generation, your 'leet hardware hacks...whatever you have, let us know! - Speaking slots are generally 30 minutes long but if you have a particularly juicy topic, we can work to find extra time. - Talks will be videoed and put on YouTube, unless you ask us not to - Tables are a mix of 6' or 8' by ~30". If you have a precise amount on linear table inches in mind, let us know in the topic box and we'll get in touch and/or reserve a specific size. - Hotel rooms are still available at the block rate. Use the link on the main page. If the show rate is not shown, perhaps our block was filled. Contact me and I will get it extended, if possible (we've had to do it twice already.)

The item is the notebook / diary detailing the restoration of their PDP8/s (or I think it is of theirs).? Undoubtedly donated by someone who may have thought it would remain there.? I suspect unless the items are going to organizations, they will show up soon on ebay. The buyer in this case showed he had done 90% of his recent business all over items from there, and if you look at their queue it is easy to see why. http://www.ebay.com/itm/221805321988 I just hope it's not one of the psychos on ebay that one has to deal with with a lot of items, but it probably is.? I'm going to go back thru the AGCW feedback given to see what else they got, but I suspect its not a collector. Any word where such items as the PDP8/s and such stand?? If the recent example of the Apple 1 donation is any indication the people that are doing the selling are probably not getting the best for their dispersion of the collection.? In the Apple case 200k is way under what it probably could have fetched, and whoever got it (and probably whoever sold it) make out like banditos. thanks Jim On 6/26/2015 12:27 PM, Brendan Shanks wrote: > Yep they started selling/giving away their collection few months ago: > http://forums.nekochan.net/viewtopic.php?t=16729439 > > Brendan > > On Fri, Jun 26, 2015 at 11:58 AM, jwsmobile > wrote: > > >? ?

I'm trying to figure out why it doesn't work on the system I'm implementing. I'm emulating the current record data in the FCB so even if a program modifies the extent or current record without a random access call, it still loads the correct sector from the file. So far, it works with WordStar 3. I'm still implementing write support. I've compared my emulated FCB to the one generated by a CP/M system and from what I can tell, the CR/EX/S2 data is the same. I've had a look at the CP/M source, I don't see anything unusual there. Really, the only thing that's different is the allocation data. I'm following the CP/M-86 convention for converting between FAT file system data and CP/M FCB's. It's documented here: http://www.seasip.info/Cpm/dosplus_fat.html Knowing me, it's something silly or trivial, but until I find it... :) Cheers, Alexis.

It was almost 30 years ago, but I recall that 22NICE translates FCB actions in ordinary handle calls--with a heckuva lot of code translating FCB actions into handle-type file actions. So probably of no particular help. WordStar is largely CP/M 1.4 compatible, IIRC. --Chucj From toby at telegraphics.com.au Sun Jun 28 21:12:55 2015 From: toby at telegraphics.com.au (Toby Thain) Date: Sun, 28 Jun 2015 22:12:55 -0400 Subject: DEC Logo In-Reply-To: <55907676.8050001@dds.nl> References: <55825BDD.6050501@btinternet.com> <20150618115440.GZ30726@Update.UU.SE> <88722826-7342-4B8F-9E58-0AD069529E1B@fozztexx.com> <55907676.8050001@dds.nl> Message-ID: <5590A9A7.4010400@telegraphics.com.au> On 2015-06-28 6:34 PM, simon wrote: > It seems to me that pdp8 is written in futura bold ITC Avant Garde would probably be closer.

I didn't have random access implemented, but now I have it works. What I don't understand is why it didn't pop up as an unimplemented function call (causing the confusion). Crisis averted.

I have a J932SE system I am interested in selling. It has 32 CPUs and if I remember correctly 2 megawords of memory. IOS-V chassis (4x VME sparcstations that network boot from Sun Sparcstation 5 SWS that provide io path to disks.) 4x 9GB hard drives. Seagate full height with Cray firmware. The chassis exist for 24 hard drives. I have Unicos 10.0.0.1 and 10.0.0.2. Not original media. I've gotten it to the point where the SWS side comes up (those run VxWorks) then Unicos starts to boot for install then kernel panics. I haven't had a ton of time to troubleshoot it. System was located in a hackerspace in Norfolk where there was needed power but went back into climate controlled storage after we lost the space. The CPU rack is around 6' deep and 23" wide internally. Has 5 x 5000 watt Pioneer Magnetics power supplies. Uses two 30 amp 220v feeds. The Disk/IOS rack is shallower (Same depth as the smaller J916 system) and 19" wide internally. Uses a single 220v 30 amp feed. It is the peak of my computer collecting hobby, but younger generation screwed out of housing opportunities so owning stuff like this is hard when you rent and get bumped around. So looking to find it a new home and stick with the plastic computers. Note, it probably need to be on a concrete floor. It weighs 2000+ pounds. Movable with a penske truck with liftgate by removing all of the boards. Looking for around $9000. Located in Norfolk Virginia. I relocated to a better area so pick up would have to be on weekends, I can drive down to facilitate purchase. Always stored in climate controlled storage. A much better deal when compared by weight to the Altair, IMSAI and Apple I systems. ;-) Rare opportunity to pick up a rare system!

What would be the best machine for a beginner to VAX > Hardware to start out with? I think you need to think very carefully about what you want this machine to do. The ideal VAX for me is not going to necessarily be the ideal VAX for you. In general there are 3 classes of VAX that people run at home. There are many other families, but in general they are much rarer, and probably much harder to maintain. The first series are the VAXstations, probably a 3100 of some kind. These are desktop boxes, they are workstations (so you can drive a CRT monitor from them, although they have serial ports too, and AFAIK can use a serial console). They generally have SCSI and ethernet interfaces built in. The downside is that they are somewhat closed machines. You have connectors for a memory board in most of them. You have the SCSI bus for disks. But you don't really have access to the CPU bus to add anything out of the ordinary. This may well not matter to you. The second series are the MicroVAX II/III machines. Normally in a deskside-size cabinet. Normally use a serial terminal, but there are exceptions. Here the CPU is one board, memory is one or 2 more, then separate boards plugging into something called Qbus for everything else. The advantage, of course, is that Qbus is the processor bus so if you need a strange interface you can probably add it. The disadvantage is that finding some of the boards you may want is a pain (Qbus SCSI is often hard to get) The third series I hesitate to mention, as I don't think they're what you are looking for. That's the first ever VAX series, the 11/7xx machines. There are 3 sub-families. The 11/780 was the first It's massive (think large wardrobe just for the CPU) and needs 3 phase mains officially. The upside for a hardware person is that said CPU is massive because it's built from lots of simple, standard, ICs. It's repairable. Very. The 11/750 came next, a bit smaller, but now the CPU is a lot of custom gate array chips. One that I would avoid (yes, I know I'll get flamed for that from all the happy owners). To me the 11/750 is large and doesn't give you anything over a microVAX The third subseries is the 11/730. It's slow. It's very slow. I am told that using the DEC supplied microcode tape it can take 25 minutes to get a boot prompt (!). But it's small, the CPU is one 10.5" high, 19" wide rack mount box. A useable machine fits in a half-height rack. And amazingly this small VAX was built from standard ICs (admittedly a lot of PALs), mostlly. These machines use an expansion bus called Unibus (the 11/780 and 11/750 also have MassBus for disks). Unibus is similar in concept to Qbus, so again you would have a board for ethernet, one for serial terminals, etc. For me, a hardware hacker with too many machines as it is, the 11/730 fits the bill. I can accomodate it (I doubt I could fit an 11/780 in anywhere) and I can hang a logic analyser off it if I want to. For you, I think you should probably look towards a VAXstation to start with. But I might be very wrong... -tony From ggs at shiresoft.com Mon Jun 29 12:23:34 2015 From: ggs at shiresoft.com (Guy Sotomayor) Date: Mon, 29 Jun 2015 10:23:34 -0700 Subject: Where to get a Vax or microvax In-Reply-To: References: Message-ID: <7ED7A07F-E50F-40A2-9DBB-FA2B00DC41EB@shiresoft.com> > On Jun 29, 2015, at 9:08 AM, tony duell wrote: > >> on real hardware.

If you'd raised this about 18 months ago, you could've picked from any in the above list (yes, including 11/780's) when I moved. To give folks an idea of how much stuff I had jammed into my (many) storage units, as I was going through them trying to figure out what I'd keep and what I would "dispose" of, I found a VAX 11/780 that I didn't know that I had. I knew that I had one in storage as I was digging/sorting I "discovered" a second 11/780 that I had forgotten was in there. You *know* you have too much stuff and it's packed too tightly when you can "lose" a VAX 11/780!

See my previous mail for a link to one revival of that family. I looked at that. There are plenty of variations, but none of them match at all. Take a look at the 11/45 processor handbook, or the peripherals handbook (for example the 1976 edition). The inside cover page is particularly helpful because it shows the company name for an additional bunch of characters. If you mix & match letters from all the different variants of Chalet (like the a from Paris 1980 but the k from Paris 1970) you can get closer. But that?s not plausible, and in any case it?s still not the same. The k in Paris 1970 is somewhat like the one in the DEC font, but it is clearly not a match: the DEC k has arcs starting at the vertical line, while in Paris 1970 there?s a bit of a horizontal line first. And none of the variants have the r in ?processor? or either of the two version of the t in ?digital equipment corporation?. paul From ard at p850ug1.demon.co.uk Mon Jun 29 12:28:05 2015 From: ard at p850ug1.demon.co.uk (tony duell) Date: Mon, 29 Jun 2015 17:28:05 +0000 Subject: Where to get a Vax or microvax In-Reply-To: <7ED7A07F-E50F-40A2-9DBB-FA2B00DC41EB@shiresoft.com> References: , <7ED7A07F-E50F-40A2-9DBB-FA2B00DC41EB@shiresoft.com> Message-ID: > > To give folks an idea of how much stuff I had jammed into my (many) storage units, as I was > going through them trying to figure out what I'd keep and what I would "dispose" of, I found a > VAX 11/780 that I didn't know that I had.

Kersqueeble! When I moved last year I found an RK05 (drive) that I had forgotten about, but that was about it. No really large machines came out of the woodwork. A tip for anyone moving in the UK. Do as much as you can yourself. I had the misfortune to use a removal company who assured me they could move the stuff and would handle it properly. Result : a heck of a lot of damage that will take years to put right, parts will have to be made from scratch, etc. And absolutely no way to get a penny out of them -tony From wdonzelli at gmail.com Mon Jun 29 12:33:24 2015 From: wdonzelli at gmail.com (William Donzelli) Date: Mon, 29 Jun 2015 13:33:24 -0400 Subject: Where to get a Vax or microvax In-Reply-To: <7ED7A07F-E50F-40A2-9DBB-FA2B00DC41EB@shiresoft.com> References: <7ED7A07F-E50F-40A2-9DBB-FA2B00DC41EB@shiresoft.com> Message-ID: > To give folks an idea of how much stuff I had jammed into my (many) storage units, as I was > going through them trying to figure out what I'd keep and what I would "dispose" of, I found a > VAX 11/780 that I didn't know that I had.

Ha! Bud sadly, I can relate. I am moving as well, and I am coming across tons (VERY literally) of racks of military radar and radio equipment I forgot I had. The good news is that as I am breaking up my radar and radio collections, I do not have to think too hard about where the stuff is going.

If it's "unusual" stuff, then move it yourself (if you're able to). Fortunately had some fore thought prior to my move. So I spent a lot of time sorting and palletizing the smaller stuff (ie anything that wasn't already on casters). I would not have been able to load the truck, drive almost 200 miles, unload and drive back all in the same day if I hadn't already had stuff "pre-packaged".

But that?s not plausible, I worked in graphic design for a long time. Modifications and substitutions of any kind are not unusual in a logo. So yes, it's plausible, but just annoying when reverse engineering it later, of course. and in any case it?s still not the same. The k in Paris 1970 is somewhat like the one in the DEC font, but it is clearly not a match: the DEC k has arcs starting at the vertical line, while in Paris 1970 there?s a bit of a horizontal line first. And none of the variants have the r in ?processor? or either of the two version of the t in ?digital equipment corporation?.

Those come under the 'many other families' I would argue that those machines are much rarer and much harder to maintain than the 3 families I suggested for a _first_ VAX.

But it's what I started with. Well, ok, if your list was intended as a "first VAX" only list, then fair enough. I would not consider most of those machines as good first VAXen either. Although, the 6000 is actually not that hard, nor some of the small 8000-machines, such as the 8200. The problem with lots of the more modern machines though, are that they essentially are fine if they work, but if they break, you'll have a hard time to fix them. That goes both for the 6000 series as well as all the pizza boxes.

So yes, it's plausible, but just annoying when reverse engineering it later, of course. For a logo, absolutely.

That explanation might satisfy everyone. :) I think it's pretty unlikely that a font will be discovered that is a better match than Chalet out of the box, though. Perhaps. I think the similarities are faint enough that I would not point to Chalet any more than I would point to Avant Garde. Designed from scratch by a guy with a set of drafting tools seems more likely to me. But unless someone with first hand knowledge comes along, as was done for the 7-block digital logo, all this will likely remain speculation. Meanwhile, if you want a font file that?s a better match than Chalet, try the ?handbook? font I created some years ago from the DEC document samples I have on hand. paul From ard at p850ug1.demon.co.uk Mon Jun 29 14:35:32 2015 From: ard at p850ug1.demon.co.uk (tony duell) Date: Mon, 29 Jun 2015 19:35:32 +0000 Subject: Where to get a Vax or microvax In-Reply-To: <55919C86.2060403@update.uu.se> References: , <559193E1.6020401@update.uu.se> , <55919C86.2060403@update.uu.se> Message-ID: > > Well, ok, if your list was intended as a "first VAX" only list, then That is what I believe the OP was asking for, > fair enough.

That is machines where component-level investigation and repair are very possible, Those series are the 11/780 (including the 11/782 and 11/785, of course) and the 11/730 (including 11/725). As I don't have space for the former, I intend to run the latter. But my requirements and interests are likely to be very different from other people's hence my initial comments. Thing about the VAXstations is that there are quite a few about that can be raided for spares. There is a printset for at least one of them on bitsavers, so I would guess finding a faulty IC is not going to be impossible. I refuse to actually suggst b***d-sw*pp**g but you know what I mean....

The 11/782 would become very big, and use even more power. Not that an 11/780 are small to start with, but we're talking about roughly doubling the size and power consumption here... Not to mention being a very odd machine from a multiprocessor point of view as well. Not something I would recommend unless you are seriously interested in that specific machine. The 11/730 and 11/725 are probably among the last machines I would ever want to have. We all have different dreams... The 8650 is sweet. I could possibly like a 9000 even more... > Thing about the VAXstations is that there are quite a few about that can be raided for spares.

I refuse to actually suggst b***d-sw*pp**g but you know what I mean.... Yeah. VAXstations makes a lot of sense for someone who just wants to run a VAX and play around. The fact that you can get spares pretty easy most of the time has its points. If you like playing around with the hardware as well as the software, then maybe there are more interesting machines around than the pizzabox ones. > I have never seen a printset for a 6000, 7000, 8650, etc machine.

That's just silly. I restored a pair of 11/785s (one a field-updated /780) for LCM. They're a wonderful machine, and I really really want one - after I win the lottery and can afford the power and space for it and can take the time to get and keep it running. Get a VAXstation of some sort or another. Even if you have a low end one-lunged 3100, or even a 2000, you can run VMS on real VAX hardware and have fun. I would actually suggest a 3100 over just about anything else because you can find expansion cases for it (typically containing SCSI drives, CDROM drives and even cartridge tape drives) pretty easily and cheaply, and everything just plugs in. If you want one of the 'good' ones, you'll fight tooth and nail on ePay, but if your goal is to enjoy running VMS on real hardware, you can buy one of the 'OK' ones for a lot less. Then, if the bug bites you and you really want something bigger, I'd look for one of the pedestal machines - I really love my 4000/300 and, although you'll pay through the nose to ship it, it's a serious VAX that can Do Stuff. Then, if you discover you're totally insane, you can look about for Big VAXen and subsidize your local power company. -- Ian On Mon, Jun 29, 2015 at 3:04 PM, Johnny Billquist wrote: > On 2015-06-29 21:35, tony duell wrote: > >> >>> Well, ok, if your list was intended as a "first VAX" only list, then >>> >> >> That is what I believe the OP was asking for, >> > > Yes.

As I said in my first posting, the ideal VAX for you is not the ideal VAX for me. Personally, I would have considerd an 11/780 as my first VAX, I know what it is like, I can read the printset, I have a good idea what to expect in the circuitry. For me, a VAXstation would have no interest at all. > > It's not exactly like a workstation or a PC.

True, about the same size as the 11/750. They are still not small, and I can't see what they would have to offer. > The 11/782 would become very big, and use even more power.

But IMHO fitting the complete VAX CPU onto 3 hex boards using standard ICs (apart from the memory ECC which used the same gate arrays as the 11/750) is an interesting, at least, bit of work. > want to have. We all have different dreams... The 8650 is sweet. I could > possibly like a 9000 even more... As I keep on saying, and I hope the OP considers this, the ideal VAX depends on who you are. As I want to get inside the CPU with a logic analyser, there are really only 2 series for me to consider. One large, the other slow. As I am short of space and not time it is obvious what I looked for. -tony From dmonnens at gmail.com Mon Jun 29 20:57:50 2015 From: dmonnens at gmail.com (Devin Monnens) Date: Mon, 29 Jun 2015 21:57:50 -0400 Subject: Digital featured on MST3K: Beast of Yucca Flats!

Since I'm broadening the scope of the announcement slightly, a more complete list of features is included, and not just what changed since last. For anyone who is currently running TCP/IP for RSX, I strongly encourage you to update to this latest version. Several improvements have gone in in the last couple of weeks. Most important change is that there now is telnet support, both client and server side. The TCP/IP for RSX that I've written is sometimes referred to as BQTCP/IP, just to make clear that it is a different product than Process Software's TCPWARE, or JSA's TCP/IP. BQTCP/IP is a rather feature rich TCP/IP implementation, which also comes with libraries for various high level languages. The API is not compatible, even at the source level, with Unix, but on the other hand, if people write some code, they will see that it is a very easy API to work with. The reasons for the incompatibilities are several, including both resource concerns and differences between how RSX works and Unix like operating systems. BQTCP/IP has tried to comply with all relevant RFCs, but I'm sure there are corners where it does not do things right. It also does not demand much resources. It do require RSX-11M-PLUS with split I/D space, and it has only been tested properly on RSX-11M-PLUS V4.6. It should work on any version 4 release of RSX-11M-PLUS, but there might be a couple of tweaks or fixes needed. BQTCP/IP is distributed in binary form, so very little compilation is required to get it up and running. However, pretty much all utilities do come with sources. The actual TCP/IP stack sources are not included. I do not have a good setup for distributing them in a sane way, and it has had a low priority on my list of things to do. But I do not mind distributing the sources as a general principle. All that said, BQTCP/IP current supports the following protocols: o Ethernet and loopback interfaces. o ARP. BQTCP/IP can use Ethernet in co-existance with DECnet, or standalone using the provided Unibus ethernet device driver. o IP. The largest IP packets supported are approximately 8KB. o ICMP. o UDP. The largest UDP packets supported are approximately 8KB. o TCP. The window is approximately 8KB in size, and TCP do manage out of order packets in an efficient way. BQTCP/IP supports the following applications: o DHCP. DHCP can be used to configure interface addresses, network masks, default gateways, DNS servers and NTP servers dynamically. o NTP. NTP can be used to set the local time. o TELNET. The TELNET server hooks in to the standard TT: terminal driver, and the number of terminals to create is configurable. The TELNET client can be used to connect to other systems. o FTP. The FTP server can serve all kind of files to other RSX systems, and can serve text and binary files to any system. The FTP client can retrieve RSX format files from RSX servers, and text, binary and block format files from any system. o TFTP. The TFTP server and client can be used for simpler file transfer operations. o RWHOD. RWHOD is a program that reports current users and uptime from RSX, for other systems to collect. o IRC. IRC is a program to communicate with other users around the world. o IRCBOT. IRCBOT is a small example robot program connecting to IRC and performing a service for IRC users. o PCL. PCL is a protocol for printing, used by HP (and other) printers over a network. The PCL implementation in BQTCP/IP appears as a print symbiont, which you can create a printer queue for. o WWW. WWW (or World Wide Web) is a service that can present hypertext information to clients. The WWW server in BQTCP/IP also supports CGI, which makes it possible to create dynamic content. o DNS. BQTCP/IP have DNS implemented as an ACP, that anyone can query to get translations between IP addresses and domain names. It also supports different users using different name servers, or private translations. o SINK. A standard TCP service. o ECHO. A standard TCP service. o DAYTIME. A standard TCP service. o QUOTD. A standard TCP service. o IDENTD. A standard TCP service. BQTCP/IP also have automatic IP spoof detection and prevention. Additional tools are IFCONFIG, PING, TRACEROUTE, NETSTAT as well as two new pages for RMD. High level language libraries exists for BASIC+2, PDP-11 C and FORTRAN-77. I'm sure I have forgotten a thing or three, but that's a fairly comprehensive list. The documentation is a weak point, but there is hopefully enough documentation to get people running, and I am happy to answer any questions, or give support if needed. BQTCP/IP is already running on the internet, and have been for a while. People who are curious to check it out can ether look at http://madame.update.uu.se/, or telnet to telnet://madame.update.uu.se and login as user GUEST with password GUEST, or use ftp against ftp://madame.update.uu.se. Anonymous ftp account exist. As usual, the distribution is available from: ftp://madame.update.uu.se/bqtcp.dsk ftp://madame.update.uu.se/bqtcp.tap ftp://ftp.update.uu.se/pub/pdp11/rsx/tcpip/tcpip.dsk The .tap file is an RSX virtual tape. It is only possible to download and use if you are using FTP from anther RSX system and fetch the file. The .dsk files are virtual RL02 images that are useful both from within RSX as well as through emulators. The documentation is also available through ftp on Madame, or also at http://madame.update.uu.se/tcpipdoc Johnny From jhfinedp3k at compsys.to Tue Jun 30 07:48:49 2015 From: jhfinedp3k at compsys.to (Jerome H.

I have successfully installed & run Win7 x86 & x64 on Dell Latitude D620, D630, D820 & D830. Not sure on the age, but they gotta be getting on to around 7 years. The RAM they have varies between 2GB & 4GB. I have also installed Win8 x64 on a Latitude D830, then proceeded to swap that drive into a D620. Yesterday, I just "upgraded" a D820 from WIn7x64 to Win10 x64 preview; 3GB RAM, we'll see how that goes... In other words, you should not be using WinXP anymore unless you have an app that just won't work with Win7. In that case, ditch the program or run in a VM. System (a), do you need that for something that won't run on (b) or (c)? I'd worry about nasties getting to it. Personally, I'd dump (a) and max out the hardware on the other 2. -- --- Dave Woyciesjes --- CompTIA A+ Certified IT Tech - http://certification.comptia.org/ --- HDI Certified Support Center Analyst - http://www.ThinkHDI.com/ Registered Linux user number 464583 "Computers have lots of memory but no imagination."

However i had a friend who is a database developer (mentioned because he's not really interested in fooling with his OS, etc.) that wanted to upgrade an older system, such as the 10 year old one. XP, lots of MS and other development environment stuff accumulated. I suggested and he did an upgrade to the best system he could find which was Core I7, etc. lots of memory, nice display, and hopefully quality hardware. He used VMware converter to migrate his system to the new hardware, with all his stuff there intact. He was able to put the main tools he wanted on thru MS sources, as he had MSDN. he still has his other system running intact on the new system with vmware player. Shared drives and it running in the background makes it about 90% like he still has all his old stuff w/o major fuss of the upgrade. After a bit of fiddling got rid of the Win8 annoyances to a dull roar. I run all my systems on a Dell 2950 server. All of the systems will "migrate" with microsoft keys between dell hardware. The above scenario is a key thing to consider. I don't know about license migration to get the Converted systems reactivated. That is a complicated issue, but no insurmountable. I also had my accountant using the same scenario, and he migrated a large amount of Tax Prep hardware across with only a license re-activation session involved. He ran his old system however, not the new one. The use of virtual desktops is my mode of operation now. Main access system is a Mac retina display equipped macbook. With 4K displays now showing up, the resolution is pretty much unlimited as far as the remote desktops are concerned. thanks Jim From dmonnens at gmail.com Tue Jun 30 07:14:30 2015 From: dmonnens at gmail.com (Devin Monnens) Date: Tue, 30 Jun 2015 08:14:30 -0400 Subject: Spacewar paper has been published!

(They've been upgraded with the PowerLeap iP3/T CPU insert with 1.4MHz Celerons, and Promise IDE controllers to run faster disks.) Although I laid in spare motherboards, CPU chips, etc so far the only problems I've had are that one of the iP3/T's died, and a mouse port died (easy to work around, using a USB mouse).

I just installed WinXP POSReady2009 on a Neoware CA10 thin client with 1 GB memory and a 800 MHz VIA CPU. It went without a hitch and MS claimes that maintenance upgrades are good through 2019. I do continue to get MSE upgrades as well. The system was a problem only in that modern up-to-date browsers require SSE2, which this old CPU does not have. Fortunately, most vendors keep archives of old software around, so I was able to install a 2103 vintage of Opera and Adobe Flash. And various flavors of Linux or BSD can continue to run even on relatively old hardware. For me, the part that matters is old peripheral support. There aren't too many new systems that are manufactured today with legacy floppy or real parallel or RS232 port support, which is why I keep these old things around. --Chuck From mazzinia at tin.it Tue Jun 30 09:19:05 2015 From: mazzinia at tin.it (Mazzini Alessandro) Date: Tue, 30 Jun 2015 16:19:05 +0200 Subject: R: Advice Requested on Life Expectancy of a PC Windows System In-Reply-To: <55929031.805@compsys.to> References: <55929031.805@compsys.to> Message-ID: <005a01d0b33f$b8e60be0$2ab223a0$@tin.it> The problem with sitting idle for long time is the same as with old systems : caps can get dry and destabilize, leading to invisible or visible issues. The videocard missing the 2nd output can be just that, but it's easy for you to check (by swapping the B videocard and making sure that it's an hw issue vs a software one). This said, we could discuss about the quality of the hw... would a new i7 have quality components, or just so so ones ? I suppose it depends on the maker/product line/etc, but you could end with something that would not even reach 7y. If considering an "upgrade", why not looking for a good bargain for a xeon 54x0 / 56x0 system, that would be subject to a good level of quality parts ?

PLUS, the backups are a breeze since I use Ghost 7.0 to back up the C: hard drive in about 5 minutes every other day producing a single image file of about 1 GB. (b) A 7 year old system that my wife uses which runs 32-bit WinXP with 4 GB of memory and 2 * 500 GB SATA hard drives. The CPU is a 2.67 GHz E8400 with 2 cores and 6 MB of L2 cache, so it still runs reasonably well. My wife uses it for e-mail, watching youtube videos and google searches. The system has probably been used about 16 hours every day and turned off every night. The battery probably needs to be replaced since the boot each day needs to reset the date / time when the boot hangs at the very start, but otherwise the hardware seems OK. The software is very out of date and needs to be replaced. Note that if 7 years is not a really long time for a WinXP system (specifically the motherboard, video card and power supply) which has been used for between 20,000 and 30,000 hours, then I could upgrade this system to 64-bit Win7, double the memory to 8 GB and, if appropriate, also replace the disk drives and the power supply. The mother board, video card (which supports two monitors) and CPU would be retained. System (c) has the identical motherboard as system (b) and was considered a replacement.

In short I think your backup and recovery strategy is more important than the machine, when running old hardware that is not CPU nor RAM dependent.

You buy a new printer and you find it only works on Windows/7 onwards. Microsoft does things to "persuade" you to upgrade... Lets take the latest Skype upgrade. Microsoft have blocked folks from using older versions of Skype, but the latest version has an un-documented requirement for the .NETv4 framework. So if you upgrade skype without it Skype fails to start missing "dxva2.dll".. No the paranoid among you will say this is Microsoft trying to get you to upgrade to Windows/7... .. the seasoned developers will say "I wonder if Microsoft has stopped testing on XP" On the other hand you do find yourself jettisoning apps which do work, often ones supplied with Windows such as Hyperterm.... > > Why do the experts advocate not using something that had been working? > > Personally, I find Win7 runs about a fast as WinXP.

The latest stuff is (obviously) only tested against the "current" eco-system, so if you find that you need a new printer or network interface or whatever, then you may be forced into an upgrade. > Microsoft does things to "persuade" you to upgrade... Lets take the > latest Skype upgrade. Worked with me. I'm running Linux now :-) Back to the original question. It looks like system (c) is the most capable and the most likely "next" platform. I'd heartily recommend the advice to try out Win98 in a VM. I'd start by installing VMWare Player or VirtualBox, create an empty VM and install Win98. If that goes OK then I'd copy across the required stuff bit by bit. (Or use the VM converter mentioned earlier if that's a suitable choice). Assuming all goes well then you know that you have a viable upgrade path when something eventually goes irrevocably south with the current system. You'd also have the advantage of being able to install multiple VMs so you could (if you chose) keep your various uses separate (if that makes sense). You probably should choose to use a dynamic disk (or disks) in the VM - that way you can specify a 100GiB disk size but the container file will only grow to the size that is actually needed. This also makes backups pretty easy: shutdown the VM and copy the container directory of to somewhere safe. When system (c) goes bang, you replace the hardware, install VMWare (or VirtualBox), restore your VM and away you go.

I have a "Core I5 2500" with 4 Cores @ 3.6GHz and 12Gb or RAM. I bought this box because I wanted to run the Hercules emulator and that can use the CPUs and RAM... However with the aid of VMware or Virtual Box I can run a host of VM's, including DOS and Windows 95 , multiple Turnkey Linux systems for playing around with Drupal, WordPress and Joomla among other things. .. its really great fun.... Only OS/2 is a little truculent.... Most things can be run virtual, there are one or two things that don't work, but on the whole its fine.

Our PDP-7 likewise has a serif face for "Digital Equipment Corporation" on its name plate, with an outline block sans-serif "PDP-7". A brief survey of the manuals for the 18-bit systems on Bitsavers shows that the change from a serif face for titles occurred during the development of the PDP-7 documentation: The preliminary edition of the User Handbook has the system name in a block serif typeface, while the release edition has the name in a block sans-serif. The PDP-6 (36-bit system) also uses the serif face; the PDP-8 is schizophrenic, and the PDP-9 et seq. use sans-serif. Note that I use the terms (type)face and logo, not "font". Until Apple bastardized the term, a _font_ was a package of metal type in a particular _typeface_, and was the unit by which type was ordered from a foundry. A _logo_ was a special item, cast as a single unit for printing, not a collection of individual pieces of type. Someone in this thread mentioned having been in the graphics design trade, and can certainly back me up on this, as well as on the fact that advertising houses and departments generally designed their own lettering for lithographic reproduction rather than using commercially available typefaces; the latter were used for printed materials consisting of large stretches of text rather than one-offs. (A company might adopt a face, or commission one, as part of the house identity, in which case the lettering done by the graphics people would probably resemble the face, but it's unlikely that it would be cast at the large sizes needed for advertising, since each size requires a set of steel punches to be engraved and a set of matrices to be produced.)

And indeed, part of my early introduction to graphic art was about some of the elements of typeface design, as it was assumed graphic artists would need that.

Clearly someone who has one (or better more) 780s (or 730s) needs to start breeding them for the rest of us. I guess to be fair I should offer that if anyone wants a 3600 and they can reproduce asexually, I'll see if I can breed the one I just got. :) BLS From v.slyngstad at frontier.com Tue Jun 30 20:29:52 2015 From: v.slyngstad at frontier.com (Vincent Slyngstad) Date: Tue, 30 Jun 2015 18:29:52 -0700 Subject: Where to get a Vax or microvax In-Reply-To: <1435711764.36487.YahooMailBasic@web184705.mail.ne1.yahoo.com> References: <1435711764.36487.YahooMailBasic@web184705.mail.ne1.yahoo.com> Message-ID: <03E5E731B0D84CF0A07146DBE4C19AC8@Vincew7> From: Brian L.

Is that the CPU that went with their NMR systems from the 70s? A few years ago I examined the RF exciter portion of a Bruker NMR that had been dismantled and sold off as surplus. Wish I knew what happened to the CPU/processing portion, but it had already been separated by the time I was involved. Something I could wish to find/stumble-across would be one of the out-of-the-mainstream minis from the 60s/70s - something not DEC, not HP, not IBM, not DG (although a little Nova would be nice). Not likely these days as they were produced in relatively scant numbers.

A few have battery corrosion issues but most of them work fine. Unfortunately, ebay, along with the sources drying up has probably greatly reduced the likelyhood of anything like them turning up for free now. If you do get something in this line, remove the battery and put up with it not keeping time or boot settings when switched off. Regards. Peter Coghlan.
