i read back as much as i could about this and most advice was to replace the ER-2055/7055 chip. i got a new one from Bob and just replaced it, but still no go on the saving.

is there something else obvious that might be causing it to not save high scores? i don't have the time to sit down and learn logic theory and trace voltages, just making sure there isn't something fairly simple that i might have overlooked.

if i can't get it done soon i'll probably see if Dick can fix it soon. this cab is going to an arcade where the owner wants to save high scores so, while the rest of the game works fine, this is something of a problem.
 
The simple stuff is checking the -28 volts to pin 14, and replacing the chip.

After that you you need to get into checking logic.
 
i can check -28v to pin 14. it does look like the molex has never been repaired or replaced so that is a likely culprit.
