EPROM Programmer Card
I just got another mystery card. I assume it's an EPROM programmer. Some of
the markings have worn off and the card doesn't indicate a model or a
manufacturer. Anyway, I'm looking for software and the manual for the card.
I've included a crude ASCII diagram of the card below. I've typed in
any legible markings and have placed chip numbers and obvious components
in parentheses.
