This is a simple circuit for programming the 28C16, 28C64, 28C256, and similar parallel EEPROMs using an Arduino. Since the Arduino doesn’t have enough pins to directly control all of the address, ...

As part of the 6809 Microcomputer there is a need to write/verify/erase EEPROM several times. Instead of buying an expensive programmer, an Arduino and a few shift registers will achieve the same ...
