Hi Ray,
It looks like a lot of machine! At least the mechanical aspects sound good.
I'd have to wonder about a 1972 vintage cnc, though. Heck, I can remember 1972 like yesterday, when a 4 function calculator was the only PC around
It would be nice to find out how a modern PC interfaces with it, what kind of software it runs on, etc. Might make a good retrofit candidate, though.
