I don't want to buy a $200 eeprom programmer to flash this chip so trying to rig one myself from an arduino. I need 16 bits for address and another 8 for data, plus a control signal or two, which is more pins than my arduino has. So I'm also including a partially complete buffer board from my Z80 computer project to buffer the data and address busses


not only did this not work but i blew up my cheap ebay power supply😬
