Does anyone know how this is done?
Apparently the 82s129 prom that is fitted by standard can be upgraded to an eeprom (2716,2732,2764,27128,27256) and also allows more channels to be added.
I have been asked by a friend if i can upgrade it for him, i have some info but could do with someone who has already done it to guide me through it.
Cheers
