The Bally Astrocade is a second-generation home video game console and simple computer system designed by a team at Midway, at that time the videogame division of Bally. It was originally announced as the "Bally Home Library Computer" in October 1977 and initially made available for mail order in December 1977. But due to production delays, the units were first released to stores in April 1978 and its branding changed to "Bally Professional Arcade". It was marketed only for a limited time before Bally decided to exit the market. The rights were later picked up by a third-party company, who re-released it and sold it until around 1984. The Astrocade is particularly notable for its very powerful graphics capabilities for the time of release, and for the difficulty in accessing those capabilities.

In the history of video games, the second-generation era refers to computer and video games, video game consoles, and handheld video game consoles available from 1976 to 1992. Notable platforms of the second generation include the Fairchild Channel F, Atari 2600, Intellivision, Odyssey 2, and ColecoVision. The generation began in November 1976 with the release of the Fairchild Channel F. This was followed by the Atari 2600 in 1977, Magnavox Odyssey² in 1978, Intellivision in 1980 and then the Emerson Arcadia 2001, ColecoVision, Atari 5200, and Vectrex, all in 1982. By the end of the era, there were over 15 different consoles. It coincided with, and was partly fuelled by, the golden age of arcade video games. This peak era of popularity and innovation for the medium resulted in many games for second generation home consoles being ports of arcade games. Space Invaders, the first "killer app" arcade game to be ported, was released in 1980 for the Atari 2600, though earlier Atari-published arcade games were ported to the 2600 previously. Coleco packaged Nintendo's Donkey Kong with the ColecoVision when it was released in August 1982.
