I had a few 620's, the most interesting was the 18-bit version.

No software to speak of for them. I even talked to the guy who ended up
supporting them down in LA when Sperry spit them out. The only thing he
had was a diagnostic tape.

Probably the most interesting Varian system I had was an integrated data
acquistion system they built with a fixed head disk and point plot display.
I'm hoping the person who bought it is able to save the software which in
theory is still in core an on the disk.


We have some software at CHM for the General Automation 18/30, which is a
little more interesting since it was very similar architecturally to the IBM
1800. The name comes from it being a cross between the 1800 and 1130.


I recovered some software for the Computer Automation museum a while ago
don't know if there's been much activity there.


Primarily, it seems the activity has been centering around people working on
various simulators for minis in SIMH.
