800XL

The Atari 800XL, released in 1983, was the flagship model in the XL series and became the most popular of all Atari 8-bit computers. It offered 64KB of RAM, a full-travel keyboard, and the same custom graphics and audio chips (ANTIC, GTIA, POKEY) that gave Atari’s 8-bit line its arcade-like capabilities. It retained compatibility with Atari 400/800 software and peripherals while introducing a sleeker case, built-in BASIC, and a new OS. The 800XL struck a perfect balance of affordability, power, and compatibility, making it a favorite in Europe and North America for gaming, education, and programming.

• Full 64KB RAM made it ideal for large games and productivity apps
• Fully compatible with 400/800 software and most peripherals
• Built-in BASIC in ROM – no need for external cartridge
• Sleek XL-series industrial design with silver and brown finish
• Supported a huge library of educational, business, and gaming titles
