>> 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.

Another case example, going from the brochures at CHM / bitsavers, in the early 70s Foxboro were marketing their unique FOX-1 (perhaps the coolest-looking minicomputer ever):
.. while their FOX-2 was a rebadged / OEM PDP-11/20 (see page 5 of FOX-2 pdf):
Out of curiousity: should any DEC-heads download the FOX-2 brochure, on pdf page 11, what is the unit above the 11/20 & paper tape reader? looks like it would be OEM from DEC, a disk or drum controller?.
