I work to repair this old controller. At this moment power on and off work, I can control coolant valve and spindle clutch. On CRT I have only 00 in bottom line. Maybe someone have working unit and can make video from start including leds od NPC52 board? I need schematic page showing dc regulators parts on NPC52, I have scans but this page are missing.

I have :
- all electric and 80% electronic schematics,
- all eprom dump, but NPC52 only from my machine, rest compared width another from internet.
