Atari 8-bit

Atari, Inc. · 1979 – 1992

Atari's home computer line — the 400, 800, XL, and XE series — used CTIA/GTIA and POKEY custom chips to deliver graphics and audio that exceeded the Apple II and outpaced most competitors. Many influential games appeared first on Atari 8-bit hardware.

The Atari 400 and 800 launched in 1979 with hardware designed by Jay Miner (before his Amiga work) using custom chips: ANTIC and CTIA/GTIA for graphics and POKEY for audio and keyboard input, with a standard PIA for I/O. The GTIA chip's sprite handling and colour capabilities exceeded the Apple II significantly, making the Atari 8-bit line the premium home computer gaming platform of its era. The POKEY chip provided four audio channels with distortion control that produced more complex sounds than the beepers of competing computers. Lucasfilm Games' Rescue on Fractalus and Ballblazer and Ozark Softscape's The Seven Cities of Gold debuted on Atari 8-bit hardware. The platform remained commercially viable through the XL series (1983) and XE series (1985) before DOS-based PCs made it obsolete in the late 1980s.
