I'll try to post some pictures of my current project soon, but I reused the
enclosures for my new electronics. If you do this you'll want to save the
spindle contactor assembly, the spindle motor overload unit, the main power
switch, the 24V power supply (if you have the pneumatic spindle speed
adjuster and brake), a bunch of the old terminal blocks, and perhaps one of
the big capacitors from the old power supply to use in building your new one.
Meanwhile, look at:

It's not exactly the same machine, but the principle is the same (power stuff
in the back, PC on the side, monitor arm on the old pendant pipe). If you're
interested, I have pre-made brackets to mount a monitor arm on the existing
pendant pipe for $50 + shipping.

Seems

There was a place in NJ that I sold some stuff to years ago, I'll try to look
up the info.

I've got them, let me know what you need to know. It's a set of 4 books, most
of which will be obsoleted by your conversion, but there's one page of
schematics that pretty well sums up the system wiring.
