1. Which machines had the CIO bus ? I know of 9K/550,
520 and at least some
version of the bus in some 800-series machines.
2. I know about 200/300/400/500/700/800-series but what is 9000/600 which
I've seen in a couple of manuals.
Some old HP 3000/9xx models had CIO bus: 925, 935, 950, 955, 960, 980.
(Possibly 930, too)
3. Is the HP 7970 tape drive vacuum column or one of
these newer streaming
devices (like the 7974A).
No...Hp 7970 is real old. No vacuum, no streaming.
A 6xx might be a special marketing version of an 8xx computer, but I
can't recall for sure.
Here are three 9000 6xx models (from /usr/lib/sched.models on HP-UX),
all are PA-RISC 1.0:
600
635
645
