The schematic is on the bottom right of

My guesses would be that your EAROM is dead (they didn't have very many
write cycles) or that the circuit to generate the -30 no longer works
(replace the caps?).

HI!

I've got another question I wanted to ask. My AD board won't save the top
3 high scores. What is the fix ? Where and what chip is responsible? Is
it a battery-backed up SRAM or something ?

Thanks again !

Steve
