How many games can use Dallas battery backed RAM without any other changes to save high scores? Can we start to make a list so we all know please. It would be nice to reply back in 1 line for each game:

game name..... Dallas BB RAM ####.... location(s) on board(s).... anything else

thanks for all your help!

I don't know the Dallas part, but MCR boards can use MK48Z02 NVRAM on the CPU board (I don't remember the location right now for some reason). That'll let you eliminate the battery on the PS, and even remove the boardset completely from the cabinet, without losing your scores. I know they work for MCRII boards, I'd imagine the same would be true from MCR, and MCRIII sets as well.

(B2 looking at the picture from my Tron... Pin 24 is marked in the picture because I made it to help someone install the chips and make sure the voltage to them was correct)

With pole position you can remove the battery and run the board with a Dallas SRAM in place of the 6116 SRAM at 7E on the board.

Dallas 1220Y

Midway TRON: replace the 6116 in B2 on CPU (middle) PCB with a Dallas 1220Y. No other changes needed. Confirmed with a friend that this works with other MCR boards (though he said he had problems with Spy Hunter, but wasn't sure if it was a bad chip)
