My first attempt at building an EEPROM programmer around the KM2865A/AH EEPROM chip. This circuit connects directly to the 40-pin card edge connector on the Color Computer, and is entirely powered by the machines bus. No 12 volt supply is needed for this EEPROM, which simplifies the circuit. 8K x 8bit should be enough for anybody.
EEPROM Proto board
I completed the proto type the other night and tested a few writes. Not sure what the eventual usage of this is, but I’ll probably use it as a capturing tool for the CoCo3 ROMs, or saving data while I try to bootstrap some programs between the assembler and BASIC (which don’t run at the same time).
