576XL - New Custom Built in 600XL Factory Case

Atari 576XL – Custom Built Powerhouse in a Classic 600XL Shell

Meet the 576XL — a freshly built custom Atari system that keeps the clean, iconic look of the factory Atari 600XL case while packing a much more capable heart under the hood.

This unit features a new custom-built system board with 64K base memory and 512K extended RAM, giving you the classic Atari experience with a serious upgrade in capability. It is an excellent choice for enthusiasts who want a machine that looks original, feels right, and performs far beyond stock.

Features

• New custom-built 576XL system board
• 64K base memory
• 512K extended memory
• Monitor port output
• Compatible with most newer Atari demos
• Nice mechanical keyboard feel
• Installed in a clean original Atari 600XL factory case

Why This One Stands Out

This is not just another vintage Atari pulled from a dusty shelf and sent back into the world with wishful thinking. This is a thoughtfully built custom system designed for people who actually want to use their Atari.

With extended memory and monitor output, the 576XL is well suited for retro enthusiasts who want better demo support, expanded capability, and a machine that still delivers that unmistakable Atari vibe. The result is a system that looks clean and classic on the outside, while bringing much more muscle to the party on the inside.

Condition

This computer is housed in a clean Atari 600XL case and includes a keyboard with a nice mechanical feel. As with any custom and vintage-based system, minor cosmetic signs of age may be present on the shell, but the overall presentation is clean and sharp.

Perfect For

• Retro computing collectors
• Atari demo fans
• Users wanting expanded memory capability
• Anyone who loves classic Atari hardware with upgraded performance

If you want the classic 600XL look without being stuck with plain-Jane stock hardware, the 576XL hits a very sweet spot — vintage style, upgraded guts, and ready for action.
