The Zikburner is an eeprom burner for a specific relatively standard set of eeproms. I built this since the ZikZak machines may want to use CPUs that need separate RAM and ROM, such as the Z80 or 6502 (or 6809, or 68000, etc.) An AVR microcontroller for instance has built in RAM and flash-ROM, so you can use it 'as is' without any extra devices to support it. An older CPU such as the Z*) will need a separate ROM IC, and a separate RAM IC. For the ROM, you can use an eeprom or eprom, or masked ROM, whatever. So, rather than buy an eeprom burner (or fix up an ancient Needhams serial one I have for arcade machin repair back in the day), I built my own.
This is why we're here, right? Don't buy something, when you can make it!
