Alternative 135 KB PDF for the 25C02 code, its name differing from the other 25C02 sheet only by a trailing underscore. It sits in the schematics category but by name concerns a 2 Kbit SPI serial EEPROM; no maker or equipment is stated.

Match the actual marking and save the original data before writing.
