I remember a Varian computer sitting in a corner of a lab at U of Illinois (computer science department). It looks similar to the ones shown in Bitsavers but not quite the same -- it had a front panel that had mostly brown coloring, and the panel was totally flat. It used membrane pushbuttons for operation, with the button positions marked by circles on the flat plastic front panel. Does that ring any bells? I remember being told it had user programmable microcode, but I never used it, in fact I never heard of anyone using it. paul
