From Pong-Story.com: The Telstar Combat (model 6065) was released in 1977. It is not a PONG system, but we decided to list it for three reasons: first, it is made by Coelco. Second, it is dedicated to a single game: tank combat, which was another classic game of the era. Third, it uses the AY-3-8700 game chip from GI, which offers four variants of the tank game. The system has a well design case with "ergonomic" joysticks.
