Hi!

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.

Regs. Ian
