Open source design: EPROM adapter for A500 motherboards of revision 5
The Amiga 500 ROM Adapter allows the usage of EPROMs in an Amiga 500 of motherboard revision 5. Compared to previous versions of the mainbord, this generation has a bug which normally prevent using regular EPROMs. Additionally, some resistors are missing which can cause stability problems.

Some years ago a detailed description of the problem Henryk Richter supplied. Using the documents of 'RetroNynjah', published on Github, an adapter board can be built which removes the mentioned obstacles. (cg) (Translation: dr)
