After the release of the Telstar (the first "dedicated-chip" pong system) in 1976 which was a big success, Coleco conceived a whole range of pongs for release at Christmas 1977. The Telstar Alpha is one of the simplest system of the range. It offers only four games and has built-in controllers. That's cool if you want to play 2 players games alone ! The only difference between the original Telstar and the alpha is that there is one more game on the Alpha (Jai-Alai).
There's a 3 positions switch that controls difficulty (BEGINNER : slow ball, big paddles / INTERMEDIATE : slow ball, small paddles / PRO : fast ball, big paddles). If this is common to the first Telstars, this is quite different from most of the other pong systems which offer individual settings.
