History of PLCs
History of PLCs
(OP)
I've also put this query on the Engineering History Forum but thought I would try here as well
I'm writing a paper about the development of programmable controllers and looking for any published information from about 1968 to 1976.
I have searched the IEEE & IET(used to be the IEE) catalogues and the first reference I can find is an IEE Colloquium from 1976.
I have a copy of Dick Morley's book and more recent interviews with him.
Any help would be appriciated

That second one is apparently written by the guy credited with inventing the PLC.

I was on a project last year and talked with this older gentlemen (older than dirt) and it was like a history lesson plcs.

The action is in Engineering History Forum. Post your answers there. Do that. And kill this thread by red-flagging it. Having the same theme in two fora is a very bad idea.
