Provides 64 KB of main RAM and 256 KB of RAMBO-compatible extended memory through a 1090XL-family expansion slot.

The page reported three cards in stock on 2026-07-27. A 1090XL or 1091XL base system is required and is not included. The PBI-memory option must remain off when the host has VBXE or Ultimate 1MB. The RAM-disable option is recommended for modern reproduction systems so other cards can map their own memory.

Expands an Atari 600XL or 800XL to 320 KB through the rear parallel bus without opening the computer.

The Tindie page reported one unit in stock on 2026-07-27. A 600XL supplies power through its parallel bus. Most 800XL computers do not, so the board provides a jumper-selectable USB-C or wired 5 V input. Follow the seller's internal-versus-external power procedure and jumper setting for the exact computer.

Adds a battery-backed real-time clock to Atari XL and XE computers as an internal module, pass-through cartridge, or circuit inside another cartridge.

The project page publishes a parts list, clock and address-decoder schematics, battery and rechargeable-cell backup circuits, and an ARC handler archive. It recommends internal installation because the pass-through and inside-another-cartridge forms may cause more problems. The page does not provide a step-by-step bus-wiring guide: an internal build must source D0-D3, A0-A7, R/W, phase 2, power, and D5xx cartridge-control signals, while a cartridge build uses the cartridge connector. No explicit project license or current assembled seller was verified.

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 cartridge-based CompactFlash or SD storage, SpartaDOS X, a real-time clock, and loader functions to Atari 8-bit systems.

Lotharek marks both generations discontinued. SIDE2 needs at least 128 KB for its FDISK workflow, and full ATR loading requires Ultimate 1MB. Some systems need a faster 74F08 or buffered O2 timing path. Lotharek ended SIDE3 sales because it could not supply firmware that worked reliably across all computers; Revision 3.2 uses a Gowin FPGA, needs its matching firmware and programming path, and does not accept the older CPLD updates. Identify the exact hardware and firmware revision before buying or flashing a used cartridge.

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.
