There was also Pong In A Chip: https://www.pong-story.com/gi.htm https://www.pong-story.com/gi.htm > General Instrument Microelectronics, also known as General Instruments (GI), was well known for designing Large Scale Integragion (LSI) chips. In 1975, GI had a revolutionar idea: the design of a low-cost chip playing several Ball & Paddle games, and available to any manufacturer. [snip] > GI's first video game chip was the AY-3-8500. It played six games: four Ball & Paddle variants and two target shooting games, which all had variable difficulty settings changed using switches. In addition, a seventh undocumented game could be played when none of the previous six was selected: Handicap, a football/hockey variant where the player on the right has a third paddle. Very few systems played this game. Interestingly, two versions of the AY-3-8500 exist: the early one with dashed central line (about twice larger) and solid horizontal boundaries. GI expanded its lineup of single-game chips but, by the 1980s, it looks like the whole concept was dead.
