Goal: replace a Mac Plus' faulty ROM chips
Secondary goal: be able to EEPROM burn new ones for various compact macs as they fail in the long run
I've purchased some W27C512 EEPROM chips (still inbound), thinking it'd be easy to use and kinda compatible with many things.
i've also bought and received a cheap ($20 ish) USB EEPROM programmer, the SP200S-2019 (it can be marked as SP200SE when you find it online but I guess I got shipped a recent revision). It normally has a Windows driver and a software called Willar programmer (wlp2000pro) but that thing has atrocious documentation and stopped being updated in 2009. Still, it supports hundreds or chips, just nothing that ressembles 24 pins 128kb and up that I need for Mac Plus ROMs (or other compacts).
Most guides online tell you how to make your own EEPROMs with an arduino unit but I just don't have the time and energy to dive into yet another uncertain project. I'd just like a beaten-path solution with a low cost (I don't want to get those big universal $200 units)
