Unisys absorbed Varian mini computers ie the V 77 nice chart in this pdf of the family tree http://rmarsh.cs.und.edu/CLASS/CS451/HANDOUTS/os-unisys.pdf by the way the purchase agreement was dated 1977 between Uni and Var we have lots of manuals in the catacombs.... unisys/varian/burroughs Ed# _www.smecc.org_ (http://www.smecc.org) In a message dated 6/9/2015 3:45:11 P.M.

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. paul
