Question
yohansen
I have a faulty Gyruss board (a bootleg I think), and my first action was to verify all of the EPROMs.
Most of the EPROMs on the lower board were in bad shape and un-readable.
Additionally, all EPROM labels have been worn off, so when programming new ones I have no idea where each one belongs on the board.
Could someone upload a photo of the lower board (assuming every EPROM is clearly numbered) or tell me the board location that corresponds to each EPROM number?
I think there are 9 on the lower board (with an additional optional diagnostic EPROM).
