The long ic on bottom center of piggy back board will almost certainly be MC33035 or MC33033, depending on pin count.
They scratch off numbers, but I have been around longer than them.
Searching my many posts you will find schematics that are fairly close.
I have not seen this version of board previously.
With all of these syil versions it is VERY important that no wires ever touch chassis, especially in front panel wiring. The magic smoke will certainly escape.
SORRY!! OOPSy. Wrong about ic. It will be atmega cpu, evidenced by the crystal.
All of these XMT boards are made be EAST CRYSTAL company.
Super X3. 3600rpm. Sheridan 6"x24" Lathe + more. Three ways to fix things: The right way, the other way, and maybe your way, which is possibly a faster wrong way.
