This is an exclusive european version derived from Magnavox pong systems (the Magnavox Odyssey 4000 has the same case), as Philips owned Magnavox at this time. It offers three games in color (Tennis, Hockeu & Squash) via a National Semiconductor chip. There are 6 game variations, automatic speed adjustment and the active player gets highlighted.
There are absolutely no button or switch on this system, all settings are made with the two buttons on the controllers. One button is used to select a game while the other one resets the game. These paddles are very similar to those of the later Odyssey²/Videopac systems, except that they have knobs instead of sticks.
