Well, Tony, once upon a time I think I was thinking about sending you
some chunks of the 7941/7945 service manual that describe some portion
of the CS/80 protocol used by those devices. I vaguely recall it was
enough of a subset that we came to the conclusion that it wouldn't
help, but if you still think it would be useful send me your postal
address and I will make a trip to the copy shop.

Also it is my understanding that the "hp300" flavors of NetBSD and
OpenBSD contain working code to talk to CS/80 devices. It may be in
the 4.4-Lite BSD release, I think that is where I remember seeing it

The CS/80 command-set reference is one of those manuals that HP Direct
refused to sell me. I had the part number, and the HP Direct folks
told me that it had been withdrawn from offer. Maybe I should give
that another shot; it's been some years ago now.


More vague memories: not all HP-IB discs talk CS/80. There was also
a "subset" or "simple" protocol, SS/80. Was that "Amigo"? I can't
remember. I think it is the protocol used by the 91xx discs, and
those are what the Integral seems to recognize.
