Well, I've replaced the battery with the proper NVRAM (if that's what it's properly called) only to still have an issue with my Pole Position II, from time to time, corrupting the high scores. What happens is when I power up I get a bunch of garbage on screen and a nasty sound out of the speakers. When that happens, it seems to be a crap shoot as to whether the high score board will be corrupted or not. I'd say it gets corrupted 30%-50% of the time it does that and it does that about every 15-20 power ups randomly (if I sit there and power down power up power down power up it doesn't seem to rear it's ugly head strangely). Any ideas? +5 now comes from a separate switcher and the board has been modded for +5 and GND to hit every test point on both boards... so that's not it (right?)...
It really sucks to lose PPII high scores...
