The Telstar Arcade by Coleco was an advanced (for the 1970s, that is) cartridge-based evolution of the then popular Pong machines that came in a unique triangular casing. As you can see above, each face of the console has been designed with a different type of game in mind. You get a light-gun, a steering wheel with a gearshift and traditional paddles. What's more, each of the four cartridges released for the machine came with several games and a MPS-7600 chip.
What's more if you are willing to risk on an untested machine --let alone one lacking the lightgun-- with a game cartridge, this Telstar Arcade auction on eBay should be of interest. Seller ships to most places worldwide.
