I believe that I have a watchdog problem on my Space Invaders cab that I am restoring. If I plug in a Space Invaders Deluxe sound board the game plays fine. With the Space Invaders sound board it just keeps resetting at the exact same point just a few seconds into the demo screen.
I can coin up the game and hit the player 1 button and the game works but then just as you are about to be able to play it resets again. I believe the problem is the watchdog on the sound board because the other sound board for deluxe work great.
Does anyone have any idea what part needs to be replaced on the sound board to make the watchdog function?
