System requirements for installing IS68K20:

	o  You must have at least two megabytes and, for now, not more than six
	   megabytes of high speed memory.

	o  You cant have color graphics.

	o  You cant use a sky ffp board.

	o  If you have a system now, and you plan to upgrade to the IS68K20
	   you must have the following boards in your system reworked:

		- memory boards.
		- icp8/16 boards.
		- gip graphics boards.

	o  Your system should contain uptodate software:
		- System Release 3.03 (desirable)
		- Graphics Release 3.03 (necessary, if applicable)

The IS68K20 upgrade tape consists of `CADILLAC' IS68K20 kernel, and a handfull 
of utilities; like ps, etc.  The tape is in tar format.  While running with 
your 68010 cpu, extract the contents of the tape using "tar xvp". Install the 
IS68K20 card, and boot vmunix.020 off of your system disk. All software on 
your system should work without recompilation or relinking. If you have 
problems with some utility please notify us (it is likely something which 
looks at /dev/kmem).

What does NOT work on the 020:

	o  The PROMs on the IS68K20 board do NOT support autobooting to
	   multi-user mode.  This will be fixed.

	o  Compiler support for C and f77 using the extended instructions of
	   the 68020 and the 68881 floating point unit will be forthcomming.
