SUBJECT: 1/2" Tape Drives


Attached is a copy of the 1/2" Control Data Corp. tape drive manual which
ISI currently uses in the manufacture of the V24 system. The other 1/2"
tape drive which ISI has used in the past is the Cipher "Microstreamer"
Model F880. According to the manufacturer, the drive passes FCC class A
and VDE 0871. ISI had RFI emission problems with the Cipher. This may
have been caused by improper or inadequate grounding.
