I suspect the microocontroller or the RAM. Alas both
are SMD (and
therefore a pain to remove), I have spares for neither and no way to get
them.
Any comments, suggestions, or things to check?
Blow a test program into ROM, and let it walk the memory?
Try and disassemble the ROM, or run it on an emulator?
