Ed: Would you recognize the system if you saw a good photo of the
controller? If there is a way I can post them, I have some shots
that might shed some light. The fact that the controller has
a "Start" and "Hold" button (along with an "Emergency Stop") makes
me think that this really is a CNC, not just a point to point - but
I could be wrong. Let me know if there is a way I could get a pix
to you. All this would be lots easier if I could power it up, but
I'm a few weeks away from being able to do that.

Thanks, Mike
