I done arcade board soldering and monitor chassiswhich kit on Ebay are you looking at? How skilled are you with a soldering iron?
I wouldn't waste my time with that. The only boards with that much corrosion that are worth saving are the unobtanium ones. I'm currently working on a Sys9 board for a Sorcerer and am hating it but finding a straight Sys11 board to use in its place is almost as bad. Don't want to pay through the nose either so suck it up and fix it.
For something like that there's a low-cost alternative out there:

And given the design of his board it is easier to run custom ROMs than if you used the original.
Practice on that board, maybe you'll save it, maybe you won't. If you do great. If not, buy Andrew's board put it in the machine and play.

Where would I go let all the partsI showed him that and he wasn't interested. I got the bare PCB for $30, and the seller even burnt the proper ROMs for Stern Dracula for me, for a nominal fee.

Here's a new method of cleaning battery corrosion with ZEP Acidic Toilet Bowl Cleaner:

I can tell you for a fact it works! I've done several severely corroded mpu boards and not only did they come out looking nice again, but I saved considerable time in cleaning the board up. The three boards I did with this "new" method worked perfectly again.
Thanks for the link Ken - I am *so* going to try this on some basket case Bally/Stern boards, as well as the other boards in my stack! This appears to be a huge time saver, with excellent results.
