Cruis'n Exotica uses a Zero Power RAM chip to save high scores. I have two PCB's here... the one in the cab would save high scores for an hour... a couple hours... perhaps a few hours, but turn off the cab, come back in a day or two... and they'd be gone. I then tried the chip on the other PCB. I was thrilled to see it would last a day... two days... three days... nice. Well, I've discovered the cut off is about a week to 10 days. Bottom line... high scores go bye bye after between 7 and 10 days.
QUESTIONS:
(1) How long should I expect a new Zero Power RAM chip to hold the info? A month? Two months? Year? Multiple years?
(2) I "assume" (you know what that means!) that this chip is re-charging while the power is on? Can anyone confirm this? If so, any idea how long I should run the machine monthly to maintain a nice solid charge?
Thanks!
