How about a photo of what the board looks like? Repairable still?

Rottendog is going to be releasing a WPC-95 CPU board later in the year, no idea on the price of it.

Either way, lets find ya a solution and get you playing again.

Hmmm, I've seen worse get fixed. It all depends on that ASIC chip and socket, which look clean but the chip will still need to be pulled to inspect it.

Not sure who to really recommend for WPC corrosion repair, but I'm sure some of the other guys have a few names to drop. If it weren't for that ASIC, I'd say send it my way, but I hate experimenting on other peoples stuff and I've done very little WPC work so far.

That should be fine for drying it off. If you're lucky, it just needed the cleaning. But my suspicion is that some of the chips and other components may also need to be replaced.

I've got all mine converted over to take 2032 coin cells. You can also do a big value capacitor or non-volatile memory. There are lot of options, and I honestly cannot see ANY logical reason that Stern still uses AA's for ROM power. Alkalines are rods of death for pinball machines.

Yep, that's the one. There's a few types out there, details vary, but all the same basic concept in that they require no external battery.

Bob Roberts has a great page on the lithium conversion for coin cells.

You can also just buy the lithium AA batteries, no board work needed. The reason I like the coin cells is that there is no temptation to just throw cheap alkalines in there next time it needs a battery replacement.

The ferro-ram is one of the non-volatiles I was referring to. I don't know WPC boards enough to say if there is a drop-in replacement or not, I know there isn't one for the 5101 in earlier boards, and you need some kind of adapter.
