Interesting. Varian is a microwave equipment company; I have one of their TWTs
sitting on my H960 at home. Vacuum equipment, I could believe that. But yes,
Varian made a 16 bit minicomputer; I had a handbook for it at one time (now
lost, I suspect). And if memory serves, the reason is that there was one in
the Computer Science department at the University of Illinois where I studied.
I remember nothing about the architecture, other than the fact it supported
user microprogramming.
Possibly the OEM PDP8 predates that device. Or possibly it wasn’t enough of a
competitor for DEC to stop doing OEM business with Varian.
