Hey, that's the 9000/834 workstation ... *HP Marketing* called it a workstation!
Up until the very day HP needlessly ripped out the code from the HP-UX kernel
that supported the graphics board ...  changing it from a 834 with local X Windows 
to a 835 with no graphics :(
(Yeah, I had one, and was using it as a workstation :)

The original name was Hewlett-Packard High Precision Architecture ...
I asked Bill Worley and Joel Birnbaum what happened to the "High" in 
"High Precision", but they never answered me.  I think it got boxed and filed 
away along with the "real time" part of HP-UX for PA-RISC :)
(At the first major public demo of PA-RISC, an HP 9000/840 was doing real
time stuff using a "newton's cradle" (aka "balance balls") toy with the swinging 
balls interrupting a light beam to cause interrupts which were then 
serviced in real-time, IIRC.)
