Some old HP 3000/9xx models had CIO bus: 925, 935, 950, 955, 960, 980.
(Possibly 930, too)

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
