Ok, this is hard to describe.

At one brief moment in history, (1983-ish?) Amtech/Reliable was installing hydros with a small microprocessor card rack. Wires mount to screw terminals, on removeable input/output boards on their front side.

The rack says GE/Fanuc on it, but they don't actually make it. It's made the mother of all PLC manaufacturers, which is Koyo.

Anyhoo, does anyone have an Amtech print from this era?
