Actually I was only concerned with the D/A and A/D boards and
termination points. Really didn't care about the controller itself.

One that I really wish I had was a UDAC. The UDAC was marketed by
Reliance Electric and was an 8 bit system that ran CP/M or a program
like it.. The control program was written in an interactive basic. If
you want a valve open that was on I/O point 197, you punched it "Let
V197 = 1" and the valve opened. IT was really cool. I installed it in
a Nabisco margarine (then a division of Standard Brands) in 1977. I
remember the 8" floppies. It was finally given to a mechanic at the
plant. His wife put it out in the pasture when they were divorced. I
found it almost 9 years later. Way too late for a rescue.
