Hi everyone! I have some EEPROMS I would like to burn (27C512, 27C256, 24C256). I have a Parallax Propeller, a Z80, a 6502, and an Arduino Uno to help me make an EEPROM burner. I know that EEPROM burners run $40+ commercially (even on EBAY!), so I would like to try building my own at home. I have an abundant supply of 74XXXX chips at home, as well as a good supply of capacitors and resistors. I don't have a Parallel Port on my computer, but I have a USB port as well as an RS232 to USB converter. I'm running Windows XP and Ubuntu - Lucid Lynx 10.04, so if I need a specific OS to burn these EEPROMS, I have Windows and Linux. I need an EEPROM burner that could erase/burn the 27CXXX EEPROMS/EPROMS/PROMS. I know through using the Propeller that I can write to the 24C256 through the Propeller, but could someone please help me in building a homebrew EEPROM burner?
