Make-It-Yourself projects
Electronics Today International, november 1976

Here is a classic project based around the AY-3-8500 game chip from General Instruments. The interesting sides of the article are the few components required to form the circuit (as the chip contains almost all of them), and the fact that a huge number of commercial systems used the same chip, so it is also interesting to know how they work. The article is a bit long compared to the simplicity of the circuits, but it is detailed and explains the games quite well.
