Replaces the Atari 800's plug-in memory modules with either 48 KB or 1056 KB of modern RAM.

Both current pages exposed active ordering on 2026-07-27, and the 1056K listing reported four boards in stock. Installation does not require soldering, but the computer's top cover and existing memory modules must be removed. Both supplied boards have a marked keyboard-facing orientation; reversing either one can damage the computer or memory board.

Upgrades an Atari 1050 disk drive with true double density, faster backup operations, and protected-disk support.

The 5cfab stand-alone Happy Warp 1050 v7.1 reproduction reported two boards in stock on 2026-07-27; Atarimax still provided a conditional add-on route on 2026-07-25. The 5cfab board includes its CPU and needs no soldering, but installation still requires opening the drive and carefully replacing internal hardware. Align the board's crystal with its clearance hole. The Atarimax guide also warns about static, alignment, and orientation.
