Hi there,
I have a really old 27c128 eprom that is faulty so i'd like to burn a replacement.
The 28 pin adapter doesnt appear to wired correctly to support this eprom as what would be A14 on the supported devices (27c512 for example) is #PGM.
I can add the support for the EPROM to the source no problem but to save some trial and error does anyone know what pin on the 56pin header the #PGM pin connects to?
Perhaps rewire it to the existing pin20? then i'm wondering what to do with that pin.. perhaps CE0? Any help is appreciated.
I have attached a diagram of the EPROM.
Regards,
Wes.
