Hey, I have lots of CS/80 drives which I stil use at work with HP1000 E/f
series computers.  I had a "CS/80 Programmers Manual" from HP which
described each command in detail.  I am currently looking for my copy since
I wnt to do a little experimentation with using a PC with GBIP card to
emulate a CS/80 drive.  If I find my manual I will let you know.  In the
mean time, if anyone else digs up one of these babies, please tell me
John
