Yes, I'd agree, an overlooked area of tech. development.
Not limited to industrial micros, I always have my eye out for early (70s period) embedded / end-use / pre-home-computer applications of microprocs.
Only managed to find a couple pieces of equipment to date. It's the sort of stuff that get's scrapped as it's not recognised or considered for what's inside.

Looks like a Fairchild F on the two ceramic LSI chips in the photo of the controller board there.
I don't recall Fairchild as a 2nd source for the 8080 but I'm not sure.
Doesn't look to be the typical amount of support circuitry for an 8080 system on that board.
Fairchild F8 system could be a possibility.
