Before uP's many used bit slice's I'm slowly putting together a
Westinghouse Numa-Logic 700 and 1200 setup. (BTW anyone have parts,
software, etc ?).
In my opinion Modicom was the best, did not need external cooling, A/B has
clout thus pretty much dominated. Did you know they used core at first and
some customers demanded it since it kept its ones and zeros when the power
went away ?
There's a few sites with URL's on early controllers, but I don't have any
written down Google Allen Bradly 1770,1771,1772,1773,1774

I compiled a quick thread on my site about the earliest use of
microprocessors in industrial microcomputers on my web site with links to
a
related article from EDN Microprocessor Design Series Volume II and scans
of Process Computer Systems product brochures. PCS was a pioneer in
industrial micro-computing.
If anyone has info to share / correct please let me know and I will add to
the thread.

Allen-Bradley had a 16-bit mini they called the 7300 Industrial
Processor. They
sold a lot of them in their 7320 (and 7340, 7360) CNC
machine tool controls. (I have one here.) See :

The row of red LEDs at the bottom of the pic is the front panel of the
7300 CPU. They had an industrial control bus that allowed you to connect a
wide variety of interface boards, like encoder counters, DACs, digital
inputs and outputs, etc. It used battery-backed DRAM, and was made around
1978.
