Looking for a Motherboard (backplane) for an IGT s+

[vashadow]

Hello,
I have an IGT S+ that has suffered a battery explosion and as such the acid has destroyed the motherboard that the MLB mates with. I have bare traces and corrosion everywhere. The board is 75903903 but I am to understand 75903904 will also work. I have fixed the MLB's battery and a few diodes that needed to be replaced. I will be replacing all the main caps in the next couple of days.

The system comes online with no displays. I can do the 61 things by holding the self-test switch and I hear a bing, then close the door and turn the key. my candle stops blinking and the insert coin light flashes twice and then the candle starts blinking again. The displays have come on from time to time so I am thinking the backplane traces are just too gone I am fairly sure I need to do a clear but without displays, it will be next to impossible. I also still need to order the clear chips.

So troubleshooting step one, replace the board that looks like it took an acid bath.
any help would be truly appreciated. I have spent days digging through the internet looking for this board. I am about ready to build my own, lol.

Attached are pics of the machine and the damage.

Just some closer shots of the board in question. Copper showing all over the board and tons of corrosion and this is after a ton of cleaning.
