looking for S100 EPROM programmer board.

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.
