Starting with Telstar Pong clone based on General Instrument's AY-3-8500 chip in 1976, there were 14 consoles released in the Telstar branded series. One million Telstar units were sold.
The large product lineup and the impending fading out of the Pong machines led Coleco to face near-bankruptcy in 1980.
This unit just needed a clean up and an RF adjustment and it was ready for action.
