Most of these boards only do one or two types of eproms. I have a bit blaster that only does 2708/04 EPROMs.
A couple hours on an extender card should be enough to figure one out, with a 'scope. They are usually not to complicated. Some latches for data and address. Some select bits and something to turn the programming voltage on and off. If it is intended for multiple EPROM types, there will be a bunch of resistors to select assorted voltages.

I ahve and can't find the manual for a: Digital research computer S100 EPROM Programmer Any info might help. Specific info needed is schematic and headers for various Eproms. Allison
