Sounds like an urban legend to me. Was there such a thing as GM's IT in the late 1960s? And if it existed, would it have the clout it enjoys today?
What is the oldest PLC system you have running?

Back in the late 1960's, GM's IT would have been known as the MIS department. Management Information Systems. Using IBM mainframes or similar.

It must have been quite an exclusive club, at the time. The first Modicon system that I replaced was installed .. maybe 1978? 984S maybe?
Saskatchewan, Canada is not exactly a progressive and high-tech mecca. But it's still a bit depressing that Modicon was around for 10 years before an industrial installation came up here.

An original AB PLC in northwestern Indiana in a grain silo. It actually isn't running anymore, replaced by PLC5s and controllogix. They still have cards for it around too. I like the online editing module myself.
