Zig Zag, arcade pcb repair

This is a “Zig Zag” arcade game pcb.
It is a clone (“bootleg”) of the classic “Dig Dug”.

As you can see, this one is in pretty bad shape with a lot of corrosion.

The pinout of the connector is also unknown since it is fewer pins on this one compared to the original pcb.
So i will have to figure out how to connect it.

I have never powered this one up, due to the obvious need of restoration. 🙂
My guess is that it is not working. 🙂

First step will be to give it a good clean, and try to reduce the amount of corrosion.
