 was originally referred to as the Bally Home Library Computer, and was released in 1977, but available only through mail order. Delays in the production meant none of the units actually shipped until 1978, and by this time the machine had been renamed the Bally Professional Arcade. In this form it sold mostly at computer stores and had little retail exposure (unlike the Atari VCS). In 1979 Bally grew less interested in the arcade market and decided to sell off their Consumer Products Division, including development and production of the game console. In 1981 they re-released the unit with the BASIC cartridge included for free, this time known as the Bally Computer System, and then changed the name again in 1982 to Astrocade. It sold under this name until the video game crash of 1983

 (memory) capacity of the systems to a tiny amount, often less than 1 KB. Although the cartridge ROM size limit grew steadily, the RAM limit was part of the console itself and all games had to work within its constraints. In the case of the especially constrained Atari 2600, which had only 128 Bytes of RAM available in the console, a few late game cartridges contained a special combined RAM/ROM chip, thus adding another 256 bytes of RAM inside the cartridge itself.

By 1982 a glut of consoles, over-hyped game releases, and low-quality games from new third-party developers less well-prepared than Activision began to appear - overflowing the shelf capacity of toy stores. In part because of these oversupplies, the video game industry crashed, starting from Christmas 1983 and stretching through all of 1984 - almost no new games were released in 1984.
