+AD4- Cool+ACE-  Singer also made computers in the early 70s.  I have a bare PCB cut
Don't forget those flight simulators+ACE-.  They were 1/2 articulation platform,
1/2 custom built computer.  I was actually the SGI system manager (among
other tasks) for the installation in Link Flight APO, Sunnyvale.
The Singer-Link Flight simulator was on the order or 6' x 6 cabinets all the
way to the early1990's.  BTW that particular computer plant (there were
others) was closed three years after they put in the Silicon Graphics
machines.  Co-Incidence?  I think not+ACEAIQ-
