| Atari released the 800XL in 1983 as the successor to the Atari 400/800 and 1200XL models. It featured a single-board design built around a MOS 6502C processor running at approximately 1.79 MHz and included 64 KB of RAM, expandable to 128 KB. The system retained the custom ANTIC, GTIA, POKEY, and PIA chips that provided advanced graphics and sound capabilities for its time. It supported up to 16 graphics modes, including resolutions up to 320×192 pixels, and four-channel audio. One notable addition was the Parallel Bus Interface (PBI), which allowed for high-speed hardware expansions. This was a key feature that set it apart from earlier models, offering greater flexibility for peripherals. The 800XL included a built-in ROM version of Atari BASIC, which could be bypassed on boot by holding down the OPTION key, often done to improve compatibility or performance. The keyboard, while less premium than the 1200XL’s, was functional and included a HELP key for system assistance and built-in diagnostics. Overall, the 800XL was a compact, affordable, and widely adopted 8-bit home computer that became one of Atari’s most successful models during the mid-1980s. |
