I could need some help writing to a 93c56.
I'm able to read the eeprom using 16 bit, but I'm not able to write it back to a eeprom. ( bit read/write works ok.
Everytime I try to write it I get an error message:
Error at 0x000001 Chip=0x7F buffer=0xFF

I've tried using:
0.97ja on PCB3
0.98D2 on PCB35
0.98D5 on PCB35
All gives the same error message.
I've noticed that the red LED is not lightning or flashing during the programming sequence.
