Radofin Tele-sports IV

Radofin Tele-sports IV is a video game console based on Pong, created by Radofin in 1978. As with many early Pong clones, the Tele-Sports IV was designed around the General Instruments AY-3-8500 chipset. The processor was actually housed inside the cartridges - this allowed the machine to be sold for a much lower price but made the games correspondingly more expensive. Only seven cartridges were released for the Tele-Sports IV. Each cartridge claims to offer up to 10 games although within a single cartridge the ten were typically variants on a single bat-and-ball theme. The Tele-Sport IV's set of orange switches allowed the game to be selected, as well as differing skill levels and background colours.
