AB made em good!
Yep, I can just see the mini PLC-2 I installed many moons ago back in the late 70's. It is probably still chugging along. They are tough little suckers if nothing else. I cut my teeth on them and had a hard time changing to the new PLC-5/SLC500 scheme of things, but once I got on to the new, I sure like it better than the old days. Not to mention using a computer to program with rather than the old industrial terminals of that era. BooHiss!
