I fixed Paddle-Ball and put it in the arcade. You can read the Repair Log here. Paddle-Ball is Williams first video game and only a few are known to still exist. My Paddle-Ball is serial number 1964-1. The only other one that I know of is serial number 614 which is owned by a gentleman in Wilmington, Delaware. You can read about that machine here. If you have a Paddle-Ball or any information about Paddle-Ball, please contact me!
