Trying to find out some antique lore.
I have a customer with a TI-545-1101 CPU. Every other week it looses it's program over the weekend. The battery is good, it just loses the program. I re-program and it's ok, I swap the CPU and the same thing happens.
I was thinking of trying a EEprom, this might help some.
Does any one know what the generic part number is for the eeprom?
Any other ideas??
