WTF? Varian was a competitor of DEC. They made
minis themselves. Sounds
extremely strange that one would take a DEC mini, and put a Varian badge

I will always think of Varian as a maker of (very high quality) vacuum
equipment.
I am sure this was not a joke. It wasn't just the name, the switch
handles
were all green, the silkscreening
was different, etc. It was a normal PDP8/e inside,
though. It was part
of a piece of lab equipment (I forget
what) and I had to do a minor repair on the PDP8/e
side (this was over
20 years ago...). I was pleased to
see that apart from a custom interface board, the rest
of it was
standard DEC boards, so the printsets I
had applied.
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.
