This guy has a shuffleboard (American Shuffleboard company) table with electronic scoring. Push buttons to add points to score for red team or blue team. On power-up, the displays light to 0-0, and a buzzer in the backbox fires nonstop. Not sure what to make of it. Does anyone have experience with these? Not sure if the buzzer indicates an error, or if it would normally indicate game start / end / score and it's just stuck, or what. There's only one board, and it's pretty simple, no obvious signs of damage, but the whole thing is IC, they could all be fried on the inside for all I know. No signs of repros or replacement boards on ebay, though I don't know naming conventions for the board.

Does anyone know anything about these?
