Quoted from FiatsRUs:I am working on the premise that my battery draining issue is resolved (I will continue to monitor this). My goal is to get rid of batteries that require replacement on all of my pins
That being the goal, is there a rechargeable option for the SAM system? It seems that installing a rechargeable battery with 3.5 vdc and putting a jumper on the blocking diode would do the trick. Not true? Bad idea? Has anyone tried this?
The SAM system debuted in 2006 with WPT, POTC was next. I've owned two POTC and worked on several. 14 years later and I've never had to replace a battery on any SAM game. Respectfully, I'm suggesting that you are trying to come up with a complicated solution for a problem that really doesn't exist. The CR2430 cells on the SAM MPU last a crazy long time, and when they do die they won't damage the board or cause any harm. I'd concentrate on games that have alkaline cells and not worry about SAM or any other games that use lithium coin cells for memory back up.
Edit to add, I guess I have replaced one battery on a Stern SAM MPU. I'm the guy that wrote the content on Pinwiki about the DS1302 being bad. So I replaced that battery that was on a Spiderman.
