DistantStar001 Posted July 14, 2018 Share Posted July 14, 2018 So this began with a problem loading ProDOS, but has morphed into something else. This bard is more for parts now, but it is still the original from my grandfather's //e, so if I can fix it, I very much want to. In short, here's what I get when I power the board: The red LED lights up, but there is no beep, and the following appears on my screen. (The first image is from my original 65C02 processor, and enhanced ROM set, the second is with the 6502, and standard (un-enhanced) ROMs that came with the replacement board). Both chips sets have been tested OK on my replacement board. This is a recent problem with this board, does anyone know what's going on?

DistantStar001 Posted July 20, 2018 Author Share Posted July 20, 2018 I reseated all of the ICs, but I'm not sure if this is progress? Quote Link to comment Share on other sites More sharing options...
