Hi all, I did a post about this in the MGoF owners here and the Gottlieb owner here. I was directed and thought about starting a thread just for this. So in a nut shell I have a MGoW everything appears to be working with the exception in the game over sound. I have 3 mpus, 1 rottoen dog, one early mpu with jumpers and one I would say stock. I have 2 driver boards. I repined most everything, cleaned the board connectors did the ground mods, rebuilt the PS . So after looking into it more since the orginal posts it seems that the signal for the game over sound sb8 is going low with a logic probe but no sound. I have put a wotking sound board into it and Its still missing the game over sound. I did ground pin 8 in attract mode and the game over did play. I just don't know why its not playing. The only thing I found between my working MGoW and this is that the one not working seems to reset after the game over a little sooner, could be with the Rotten dog mpu?
