Ok here is the question,

I have a Sammy, WanTouchable Pachislo machine.

On the board / module on the inside of the door behind the display that shows the payout combinations, there is a small battery soldered to the PCB (upper right hand corner ot the board). I hope it is not critical, such as providing power to RAM memory for sound, lights, etc.. I am thinking I should replace it before it goes dead and kills my machine, any suggestions, or ideas? I do know to provide uninterupted power in parallel with the battery before removing and replacing it to prevent possible permanent damage. Any advise will be greatly appreciated!

Thanks,

Rob
