To get this to work we need be able to drive all three of the EEPROMs control lines. Even the Chinese ones (It actually depends on the place, here you can pay overpriced from some scumbag or try to import and probably be taxed). If you are here because you built the Ben Eater EEPROM Programmer, note that the designs are similar, but the TommyPROM code will not run on that hardware without some significant changes. Since the Arduino doesn't have enough pins to directly control all of the address, data, and control lines of the EEPROM, two 74HC595 shift registers are used for the 11 address lines (15 for … But, if you don't have an Universal EEPROM Programmer, with an Arduino Nano (or another) and with few components you can build an EEPROM Programmer easily (visit github repository of Ben Eater and watch the video " Bulild an Arduino EEPROM Programmer " of Ben Eater Youtube Channel).
