A classic pong system which uses the GI AY-3-8500 chip, thus playing the 4 basic pong games. No shooting games here...
Something rare for that time, the two tiny controllers are not hardwired to the system. This means that when one of them died, it wasn't necessary to change the whole system.
The shape of the case is weird. It looks like a case conceived for a small computer. Indeed there's enough room for a small keyboard instead of the actual panel control, and the bulk at the back could have contained a mother board or any other hardware...
Actually, this bulk is used to store the controllers when the system is not used, and there's also the cells compartment.
When the system is opened, one can observe that under the control panel, several holes in the plastic case are not used by the system and are hidden by the black plastic film. For example there are two other holes for addtionnal controllers plugs. It thus can be imagined that the same case could have been used for 4-players game systems...
It is also interesting to note that many different brands used this particular case. The Alex Video Spiel TG-621 for example is the same system.
On the electronic board is written : 60-10621-01
