My parents got me two video game consoles that came out in 1977.
The Magnavox Odyssey 2000 was similar to the Atari Pong. Both Magnavox and Atari came out with their version of Pong in 1972. Magnavox sued Atari for patent infringement in 1974 and won their case in 1977. Atari paid $700,000 for a licensing agreement.
The Coleco Telstar Combat was a tank combat game. A pair of fixed joysticks controlled the movement of each tank and the button fires the gun. Players maneuvered their tank around the walls to shoot at each other.
Both consoles hooked up to the TV via the TV/game switch box. That switch box would hold a prominent place in my life for the next 15 years.
