A Guide by [[Cholo]]
Quick little guide on how to use a modern (cheap) Willem programmer board to backup your old Amstrad roms or make new ones.
- A Willem Eprom programmer board v3.x or better (+cable & power adapter).
- a couple of empty/erased eproms.
- a pc that has a parallel port (DP25).
== Used in this guide ==
Used a Willem v4.5 board and software 0.98D in the pics, but the other version boards/software works just as well.
== Amstrad (ep)roms ==
Amstrad rom are usually 16kBYTE .. so using 128kBIT chips is the way to go. So hunting down a couple of 28 legged 27128 or 27C128 eprom chips (cleaned/erased/empty) and you are ready. Please note that i said USUALLY .. there are a couple roms that has a different size .. still .. you can fit a smaller rom quite easy into a larger Eprom if needed.

First install the software (like setup_98d5_PCB45.exe).
Reboot you pc and double click the xp_stop_polling.reg if needed (donno about Vista).
