Varian bought the design of the 620. I forget the name of the original
firm, but I have a brochure on it.
Weird things happen. CDC rebadged small VAX machines and Nova 3s, for
example, even with their minicomputer line intact.

> 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.
