For some reason, my 90B gets an error when trying to program this Catalyst EEPROM. It's able to program 4 or 5 bytes before it errors out. I have tried two CAT28C64's with the same result. Oddly enough, I see in the TOP forum that someone had a similar issue with this same part on their TOP2004 programmer. Anyone have any ideas?
ZLM: do you have any connection with the factory to submit bug reports?
