context_page_description: 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, 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.
context_section_description: An equivalent to the AY-3-8500 is the TMS1965NLA manufactured by Texas Instruments.
  The Soviet K145IK17 (Russian: К145ИК17) has a built-in counter, making it possible to use a momentary pushbutton instead of a multi-position switch to select games. The handicap game is not hidden, it can be chosen among others using this button. Since a pushbutton occupies only one pin, this IC has less pins.
  A competitor was the National Semiconductor MM57105.
