Conic TV Sports TG-621

Conic TV Sports TG-621is a classic pong system which uses the GI AY-3-8500 chip, thus playing the 4 basic pong games (without the two shooting games). Something rare for that time, the two tiny controllers are not hardwired to the system. This means that when one of them failed, it wasn't necessary to change the whole system. The case looks like its been conceived for a small computer. The bulk at the back could have contained a mother board or any other hardware but it's used to store the controllers and there's also the battery compartment. The Alex Video Spiel TG-621 for example is the exact system, just rebranded. 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 additional controllers plugs. It thus can be imagined that the same case could have been used for 4-players game systems.
