This is a typical system using catridges based on the different chipsets developped by General Instruments in the late 70s. Each GI chips was able to generate several games, ball games for a start, then later car racing, motorcycle, submarines, tanks and shooting games.
The system has two detachable controllers with one analog joystick and one fire button each. The control panel is composed of 10 buttons to select the different games offered by each cartridge (10 being the maximum). Difficulty switches, power switch and a start button can also be found. There is even a volume control slider which is quite uncommon on this type of system, and very useful too!!
Systems with green and orange buttons can be found (see "more pictures" section).
