I have 3 tested and working boards I tried 2 untested g07 chassis then finally pulled a working g07 chassis out of my joust and still the game looks like this no matter what chassis or board I put in What am I missing?

does't joust use positive sync with each "sync" being separate?

whereas frogger I though used negative composite sync?

I'm pretty sure that's the case and if so you need to use the other sync connectors and provide a composite sync.

I'd have to double check that but I though the Williams games where different and the hookup you have is using the positive separate sync signals if I recall.
