+
+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.
