This is a handheld pong, since everything is contained in one handheld controller.
It is the same system as the Radio-Shack TV Scoreboard. See this entry for more info. However, the system pictured here does not have the shooting games implemented, it's the 4 game version.
We need more info about this pong ! If you designed, used, or have more info about this system,
please send us pictures or anything you might find useful.
