Atari PONG, 2 player versionuP 8108
The AY-3-8500 Ball & Paddle integrated circuit was the first in a series of ICs from General Instrument designed for the consumer video game market. These chips were designed to output video to an RF modulator, which would then display the game on a domestic television set. The AY-3-8500 contained six selectable games — tennis (a.k.a. Pong), soccer, squash, practice, and two rifle shooting games. The AY-3-8500 was the 625-line PAL version and the AY-3-8500-1 was the 525-line NTSC version. It was introduced in 1976, Coleco becoming the first customer having been introduced to the IC development by Ralph H. Baer. A minimum number of external components were needed to build a complete system.
The AY-3-8500 was the first version. It played seven Pong variations. The video was in black-and-white, although it was possible to colorize the game by using an additional chip, such as the AY-3-8515.

The AY-3-8610 was a major update from General Instruments. It played more games (10), like basketball or hockey, with higher-quality graphics.
It was nicknamed Superstar by GI. It was in black and white, although it was possible to add color by using an additional AY-3-8615 chip.
Prior to producing the 8610, GI created the AY-3-8600. The pin configuration was the same as the 8610, but it was missing the two rifle/target games, bringing the total number of games down to 8.

Four versions of this chip are known to exist. Each of them contains customised circuits adapted to the games played. For example, the Ball & Paddle version (MPS-7600-001) plays four games for two or four players and uses special paddle and ball generators. This particular chip was also released in PAL format as MPS-7601. So far, only Commodore is known to have used it in a system (model 3000H). Only one manufacturer used all of the MOSTek chips: Coleco (see the Telstar Arcade and Telstar Gemini systems). All others used the MPS-7600-001 chip.
