This is an obscure Argentinian pong powered by a General Instrument AY-3-8500-7 chipset. Though it looks like a classic pong system, it is interesting for at least two reasons.
First, the paddles are built with calculator or remote control plastic cases !! Indeed, once opened, you can clearly see the holes planned for the plastic keys (see "more pictures" section)...
The second unsual fact is that, thanks to the GI AY-3-8500-7 chipset, the system offers a game rarely found on most pongs : Fútbol de 5 (soccer with 5 players)! Indeed one player control 3 paddles and the other "only" two... that is weird.
Thanks to Sebastian Rho for pictures & info

For the 5-players soccer game (in fact 2 paddles for left player and 3 for right one), it is a non-documented game. It is normaly possible to play it on any pong system (GI chipset powered) if you can manage to not select any game (game switch must not indicate any game). Some systems, like the Interton Video 2400 if I recall correctly can play this game though... I don't know what differences has the AY-3-8500-7 compared to the standard AY-3-8500 version... I know there is also a AY-3-8500-1x but I have no info about it. It is certainly a question of internal revision.
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.
