Hello all, really trying my luck here: does anybody have a DATA I/O 21A (E)EPROM programmer and can help me with some tests to understand if mine is working well? It appear to program most common EPROMs just fine but failed on the uncommon MCM68764 which I believe is good instead (but I have only one...). Sure, the MCM is a 1980 vintage, but it was NOS. Anyone? Thanks Frank IZ8DWF
