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.
