This pong unit is very common in many ways. It uses the same plastic case as many other systems, and is powered by the General Instrument AY-3-8500 chipset which equips most pong units of that time.
This chipset offers 4 ball games (Football, Soccer, Handball, Tennis) and 2 shooting games which are not available on this system as there is no option for a light-gun. This was a common solution to seemingly develop a whole range of system with the same hardware ;-)
The controllers are very basic: two small detachable paddles. Game selection is made through a bit knob in the middle of the control panel. All other options are selected with switches.
Though the score of each game is displayed on the screen, the unit is equiped with two sliders marked from 0 to 10 to keep track of the general score of the two players, thus enabling to compete over several individual games.
