From Pong-Story.com: The Telstar Alpha (model 6030) was released in 1977. It is a classic from Coleco, and uses the AY-3-8500 game chip. The system plays 4 games in three difficulty levels. It is the successor of the three older models (Telstar, Telstar Classic and Telstar Ranger), and only differs by its case and fourth game (JAI-ALAI, also known as SQUASH). Like the first Telstar, this system was sold in large quantities as it was cheap. It was also released in Europe as the "Telstar Alpha Europa".
