I was having an issue with a Bally “Supersonic” pinball machine randomly resetting/rebooting. The problem was traced to irregular power coming off the driver board. In this video series I go over a necessary process to bring these old boards back “up to spec” as well as a few improvements that make the game overall more reliable.
Today’s I’m looking at a 1978 Bally “Supersonic” pinball machine. A friend had this in storage for a long time. While the game was in pretty good shape for its age, the original MPU board still had the battery on it, and the electrolyte from it leaked all over and damaged many components. Here’s a first look at the game.
