AvailableChecked Jul 27, 20265cfab Atari 400 Memory Boardsby 5cfab

Replaces the Atari 400's internal RAM board with either 48 KB or 1056 KB of modern memory.

Both product pages reported five boards in stock on 2026-07-27. Either installation requires disassembling the computer and soldering four jumper wires beneath the main board. A machine previously fitted with Atari's 48K RAM Expansion Kit may already have those jumpers. The 1056K board does not require the plastic-housing modification described in the older Atari kit instructions.

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.

AvailableChecked Jul 27, 2026Incognito Goldby Sebastian Bartkowicz / Lotharek

Transforms an original Atari 800 with configurable memory, XL/XE operation, CompactFlash storage, flash firmware, SpartaDOS X, and a real-time clock.

Lotharek exposed a current login-or-register-to-buy path on 2026-07-27 and describes Gold as a final 50-piece production run. Installation is an extensive internal modification: it removes the existing RAM cards and personality/ROM board, replaces the Z101 74LS42 with a ribbon connection, adds motherboard jumpers and auxiliary signal wiring, and optionally modifies the power board for an ATR button and activity LED. The installation procedure therefore makes Incognito an alternative to the 5cfab Atari 800 memory boards and RAMROM personality card, not a documented stackable addition. Retro Lemon warns that self-installation damage is not covered by its warranty.
