The Heathkit GD-1380 kit was released in 1976 and it looks like an old car radio... It plays the six games of the AY-3-8500 chip, and has several interesting features. First, it requires a Heathkit TV set to operate because of its composite output.
Back in 1976, only monitors and hi-tech equipment had a composite input. To use this system, the user had to open his TV set in order to connect a few wires to its electronic circuits. This is the case with the Heathkit TV sets: the user manual explains how to connect the system to several TV sets released by Heathkit. The Lightgun reminds those old laser guns from old TV series. It is quite ergonomic, but uses a simple push-button as trigger. The case is still excellent.
