willem eprom error
Hi!
I have old single side programmer (maybe pcb3 or older). I use it with dip32 to PLCC32 adapter for programming SST 39VF512 device. Possible to read, but the erase and write failed.The eprom content stays untouched. The vcc voltage reducated to 3.5V with 2 diode.The programmer working fine with serial and microwire eprom.
What should i check first?
