I just bought a bunch of stuff from jameco for my z80 system, as well as parts for this linux eeprom programmer. I have every thing i need now (for both projects), except i accidentally ordered 1 74ls259 instead of the two that i need! Now i can't finish the EEPROM programmer, and once again my z80 is on hold!
Is there a way around this (as in a combination of ics to imitate the functions of the 74ls259?) or am i going to have to waste some more time and money and order from jameco AGAIN just so they can charge me an arm and a leg, and force me to wait for 2 weeks before i actually have it?
Or does anyone have any other parallel port eeprom programmer schematics for linux? i guess DOS would be ok, too...
