Does anyone have the documentation for the Copam EPROM Writer for the
Apple ][? It's got a ZIF socket on it and the software in ROM, but I am
having trouble reading any EPROMs so I want to make sure I'm inserting
them properly (the board and socket have no markings).
The think I'd do first is find out which pin of that ZIF socket is
grounded. It's very unusual for a programmer to put any form of switching
circuit in the ground pin, that one is hard wired. And it'll tell you
which way round to insert the EPROMs.
