Tele-Spiel [Model ES-2201]

Like the Magnavox Odyssey 100, there is no on-screen scoring, hence the presence of cursors on the system case to mark the scores. The controllers use uncommon linear potentiometers (usually, rotative models would be used).

The system uses semi-analog circuits: discrete components including seven basic integrated circuits (CMOS type).

In addition to the Tennis cartridge supplied with the system, four others could be purchased separately. All contain a small circuit board with discrete components (resistors, capacitors, transistors, diodes, etc.) and no integrated circuits. Their circuits enable the necessary graphics generators, set the shape of these graphics (square, rectangle, vertical line, etc.) and manage various events such as collisions. The controllers plug to the cartridges instead of the system.
