[https://enThe Atari 8-bit computer series, launched in 1979 as the Atari Home Computer System, included the Atari 400 and 800.wikipediaPowered by the 8-bit MOS Technology 6502 CPU and custom coprocessors, these computers offered advanced graphics and sound for their time.org/wiki/Atari_8Video games were a major focus, with Star Raiders (1980) becoming a standout title. The Atari 800 was the high-bit_family end model, while the 400 was a budget-friendly option with a membrane keyboard and 8 KB of RAM. Both shared the same CPU and supported plug-and-play peripherals via the Atari SIO serial bus, a precursor to USB technology. The architecture was later used in the 1982 Atari 5200 console, though the systems were not software-compatible. Newer models followed, beginning with the short-lived 1200XL in 1983, replaced by the 600XL and 800XL. After Atari Corporation took over, the 65XE and 130XE were released in 1985, featuring a lighter design, two joystick ports, and built-in Atari BASIC. The 130XE had 128 KB of RAM. In 1987, to compete with gaming consoles, Atari repackaged the 65XE as the XEGS, a hybrid console-computer compatible with 8-bit family on software and peripherals. This marked the other WIKI]final chapter of Atari’s 8-bit computer line.
