MBO, a popular German electronics manufacturer, produced a large serie of pong systems named "tele-ball" with numbers ranging from 1 to 9. Though they had some cosmetic differences, all these systems were very close to each other in terms of functionality.
The Tele-Ball III is thus very similar to the original Tele-Ball or Tele-Ball II, offering only the 4 classic pong games in black & white. As usual with MBO, the different systems are quite different cosmectically, but very close in termes of functionality.
The dial on the front panel is used to select the different games. Then 6 switches are used to select the different game options. Two red buttons acts as Reset button and Manual Service.
