Gregg, another thought: Your litle machine seems to be manufactured in a very professional manner, probably rather expensive since they had it made in Switzerland (double prices compared with Germany, but very high quality), for internal use in the key lock manufacturer's company. So, once this machine was essential for their production. No consumer junk. So I think, the electronics will also not be home-brew from some garage electrician, but will consist of professional stepper boards and other hi-rel components, too, which will be identifiable. And they most certainly didn't invent a special computer for running it, but used a standard IBM-AT type PC. Probably it's only a question of a special adapter cable, maybe even to a standard PC printer port. This is almost all you need for using LinuxCNC.
I assume the machine is electrically ok and gives some signs of it when switched on. So, open the electronics box on the rear and let me have a look at the interior. I suppose there will be one to three boards for the steppers and some more electronics for the spindle motor. If these are professional items, too, there will be a manufacturer's label in the boards, type number etc. Mail me some pictures, will you? It should be possible to find out how the steppers are wired. Too bad I can't have a look myself, because figuring out how these thing runs would be not so far out. Maybe I can find the driver board's manufacturer, wouldn't doubt it. They are usually more cooperative.
