Loads cartridge images and XEX files from USB-managed flash storage through an inexpensive RP2040-based Atari XL/XE cartridge.

A8Renegade's live Shopify product data and collection reported the assembled cartridge orderable on 2026-07-27, despite a contradictory sold-out label in the rendered product page. The complete open design also remains buildable.

Provides blank flash cartridges and a USB programmer for building reusable Atari 8-bit multicarts.

The official page showed the cartridges and USB programmer in stock on 2026-07-25. These are blank programmable products and do not include commercial ROM images. Unplug the programmer before attaching a cartridge, verify label-side-up orientation, and connect directly to the PC rather than through a USB hub for first-time use. Backwards insertion can damage both the cartridge and programmer.

Adds CompactFlash storage, cartridge-image loading, and onboard flash and SRAM to Atari XL and XE computers.

The official page showed MyIDE-II cartridges and accessories available on 2026-07-25. A prepared CompactFlash card is offered separately, so confirm the selected package contents. No ROM images are included; users must supply legal images and software.

A family of SD multicarts for Atari 8-bit computers, ranging from cartridge loading to disk, tape, memory, clock, and audio expansion.

All three product pages showed In stock and Add to cart on 2026-07-24. Optional SIO, ECI, PBI, and DAC cables are separate. SUBCART's extra functions need ECI or PBI, and the maker does not recommend them on a machine with U1MB or another third-party internal memory expansion.

Adds IDE hard-disk storage through cartridge, internal flash-OS, and original Atari 800 DIY implementations that predate MyIDE-II.

The official Atarimax page said the interfaces were in stock and extended its sale through 2026-07-31 when checked on 2026-07-27; verify that short-lived offer before ordering. The family has been superseded by MyIDE-II but remains functionally distinct because it accepts IDE devices rather than providing MyIDE-II's onboard CompactFlash and FAT32 loader. The cartridge requires a 64 KB XL or XE. Internal installation ranges from an OS-ROM socket plus three signal wires in an 800XL to extensive socket, jumper, MMU, BASIC, and wiring changes in a 1200XL. Mr. Atari's original 800 version is an advanced personal-use DIY design with schematic and firmware files but no complete build instructions or bill of materials.

Emulates writable Atari XL and XE floppy drives from SD storage using the original ATmega8 SDrive design or the NUXX packaging variant.

The original GPL-3.0 hardware, firmware, Atari-side software, documentation, and source remain public. Its 2009 documentation specifies cards up to 2 GB with FAT16, while the repository also contains a later 2012 SDHC-supporting source revision; match the firmware, media setup, and documentation deliberately. The NUXX archive is frozen as of 2020 and says its function is identical to original SDrive, but adds a different PCB, enclosure, connector options, and optional STK200-style parallel-port programmer. No current assembled seller was verified.

Reimplements SDrive around a 48 MHz Cypress PSoC ARM controller with microSD, capacitive controls, eight drives, and cassette emulation.

The repository publishes Eagle hardware files, PSoC firmware, update binaries, documentation, and enclosure models. Initial controller programming requires a Cypress KitProg-compatible programmer and the source expects the older PSoC Creator 4.0 toolchain. The latest tagged update is from 2018 and fixes FAT16, large ATR and 256-byte-sector handling, applies Hias patches, and improves SD-card compatibility; the last repository change shown is from 2022. No current assembled seller or explicit repository license was verified.

Emulates Atari SIO disk and cassette drives from microSD storage with an Arduino and touchscreen.

The Brewing Academy kit was sold out on 2026-07-24, but the firmware and build files remain public. Its kit still requires assembly and part of an SIO cable. The official project strongly recommends external power because the approximately 150 mA load exceeds the Atari SIO specification; follow its wiring instructions carefully to avoid back-powering the computer or device.

Provides open internal and currently assembled external SD-based SIO disk-emulator variants for Atari 8-bit computers.

Lotharek exposed a login-or-register-to-buy path for SD Drive Mini on 2026-07-27, and Retro Lemon also listed it with pricing. It plugs directly into SIO, uses a FAT32 microSD card and SDRIVE.ATR, and provides two buttons plus LEDs for selecting four drive slots. The separate open SDrive-Simple-II build still requires PCB assembly, ATmega328P programming, and an internal SIO connection. Its documented firmware supports cards up to 32 GB and ATR and XEX files, but not CAR, ROM, ATX, XFD, or CAS files, and it has no control for swapping disks in a multi-disk title. The former SDriveXEL assembled source and exact public build package remain unavailable.

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.

Turns supported Arduino hardware and a microSD reader into a single Atari 1050-compatible SIO disk emulator.

The maker says SIO2Arduino has been superseded by SDrive-MAX and is no longer actively developed, but its GPL source and detailed wiring instructions remain online. It currently emulates only one D1: drive. A build needs a supported Arduino Uno, Mega 2560/ADK, or Teensy 2.0, a compatible SD reader, the specified SdFat library, an Atari SIO connection, and configuration matched to the chosen hardware. LCD and physical controls are optional.

Emulates Atari 8-bit disk drives from SD or MMC cards through the SIO port.

Lotharek offered the Biggus Dickus, metal-cased XL and XE, and color variants through login-to-buy paths on 2026-07-27. The metal-cased versions include an SIO cable, while the base Biggus Dickus listing includes neither cable nor SD card; other listings bundle those accessories with the same hardware. The official project also publishes Eagle schematics and boards plus firmware, making a DIY path possible. Upstream firmware reached 3.3 in 2023, while Lotharek says its assembled versions use customized 3.1 RC2 firmware, so do not assume identical features without checking the installed version.

Reprogrammable multi-mode cartridge for Atari XL and XE computers, prepared with modern-host and Atari-side tools.

The maker's linked ABBUC product URL returned 404 on 2026-07-28, and human review found that ABBUC no longer appears to operate a store. No current direct order path is known, so treat the cartridge as a used-market find unless the maker announces another batch. The maker page, Studio, and Atari-side flasher remain available; its separate WUDSN hardware-details link is also dead.
