MBO, a popular German electronics manufacturer, produced a large serie of pong systems named "tele-ball" with numbers ranging from 1 to 9 (or more ?). Though they had some cosmetic differences, all these systems were very close to each other in terms of functionality.

The **Tele-Ball IV** is very similar to the **Tele-Ball "I"**, though its display is in colour. This is the major difference. The plastic case is the same. Only vertical sliders on the controllers and a tiny red "service" button have been added onto the system.

Thus the Tele-Ball IV is basically the colour version of the Tele-Ball "I". It only plays the four basic pong games (tennis, hockey, squash and practice).

The two big silver dials on the front panel are used to switch the system on/off and to select games.
