Thanks!
So i kept working on the game last night, tried to figure out what PCB they had in the cabinet when I got it.
This is how they had wired the Video signal, they tied RGB and Sync together to send it to the B&W monitor... there is a pot on each of the RGB-wires...

How do you quicktest this, I figured out the easiest way were to take my small PVM and BNC-alligatorclip wires

Didnt know if this should work or not, I hooked them up at the potentiometers.

It worked straight away, dont know if the colors are correct, I supect not, but the PCB works and sound is working, I have not tried any inputs though..

So what game is it? It says Universal on the PCB:s so my guess would be Cosmic Monsters

My next step is to clean the cabinet and then wire Space invaders in there instead.
I made a plan for it last night ....
