28c256 Eeprom Programmer, Use Ben's Arduino EEPROM Programmer - it works with the 28C256. It currently supports 28C16 (2Kx8), 28C64 (8Kx8) and 28C256 (32Kx8) EEPROMs, but it will probably work with all 28C-family (having all the necessary address-bus pins). Other than that it looks like it functions in exactly the same way as a 28C16, as used for the 8-bit computer. When most people have issues with the breadboard programmer it's usually a timing Mar 19, 2026 · Build a cost-effective Arduino EEPROM programmer for reading and writing chips like the 28C256. - Andy4495/ParallelEEPROM A simple parallel EEPROM programmer based on Raspberry PI (model 3). The board provides both a 27C256 pinout for installing in place of mask roms and uv eproms, and a 28C256 pinout for programming directly in a programmer, by changing jumpers. The original code was specific to the 28C256 32Kx8 EEPROM, but it has been extended to also The EEPROM writes are implemented as page writes where all bytes of the received intel HEX row are programmed at once. .
