I wasn't trying to describe _all_ HPIB drives, just the Commodore D9060
and D9090 drives. Your 7958 sounds like a perfectly valid way of doing
things... in fact, since it uses a 1355, I'm sort of intrigued (since I
have a few on the shelf). I'll have to try to remember that HP model
number when I'm digging for drive docs.
