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 and the first computer RPGs appeared on Atari 8-bit hardware.

The Atari 400 and 800 launched in 1979 with hardware designed by Jay Miner (before his Amiga work) using three custom chips: CTIA/GTIA for graphics, POKEY for audio and keyboard input, and 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. Games like Rescue on Fractalus, Ballblazer, and The Seven Cities of Gold from Lucasfilm Games (later LucasArts) debuted on Atari 8-bit hardware. Richard Garriott's early Ultima games originated here. 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.
