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.

Adds configurable expanded memory, flashable operating-system slots, SpartaDOS X, and a battery-backed clock to Atari XL and XE computers.

The Brewing Academy collection marked its 2026-version package sold out on 2026-07-24. Lotharek still exposed a login-to-buy path for a closely related regular-firmware version. The TBA package includes the board, MMU and OS ROM adapters, a four-wire cable, and mounting parts, but no printed manual. A board without socketed MMU and OS ROM chips needs desoldering and new sockets; those sockets are not supplied.
