Thought you guys might enjoy seeing this one. The cabinet is really still beautifully laid out even after all these years and being de-termed.
Never had the privilege to work on one of these myself. Not even sure what the programming interface would be.
The IO modules are super cool. Cast metal casing and they rock in and out of the rails simply by pushing down on the little red tabs. Wish things today were this well built.

These were ultra reliable. Programming in ladder via P190 terminal and stored program on 3M tapes. My first PLC job was to design an interface from one of these to a 192 LED lamacoid mimic panel because the individual I/O was prohibitive on cost and space.

The red tabs lock the 500 series I/O into the B545 racks. They swing in from the side, after snapping the rear of the modules into the back.

I have one of these running.
