This is a very common european system. It was released by numerous manufacturers such as Intel (Germany), Asaflex, Univox, Interstate and others, and exists in two versions: 4 and 6 games (model 105 ?). The case can be black or white and the controllers can change.
It has big orange buttons and large game selection wheel. It was released in 1977 and uses the popular AY-3-8500 chip grom General Instruments offering the 4 classic pong games : Hockey, Tennis, Squash and Squash practice. The other version (model 105?) often with white case, adds two shooting games.
The fun fact is that the controllers are attached to the console by "scratches" !
This pong was made in Hong-Kong...
