Easiturn Homing Proximity Sensors

I am curious and my inner Scrooge would like to use the old two wire proximity switches but the attached electronics is long since gone.

Re: PNC2c Lathe electronics/electrical diagrams

Couple more photos uploaded and questions below: The armoured cable that housed the X axis stepper motor signals to the carriage was one of the shockingly scary bits, it had been continuously rubbing on the bed of the lathe, poor routing choice at some point..

Hello, I have taken ownership of a neglected lathe. It seems that it started life in 1982 at a University and then its history is a bit vague. It has sat un-used for the last 9 years, I think the last owner may have had it working with an inverter for the main spindle and I suspect the joystick only...
