Atari 1040STE upgrades

Uses an STM32 and SD media as a mature open Atari ST hard-drive emulator with ACSI, disk-image, and GemDrive modes.

For this system (exact model): The upstream compatibility matrix reports multiple successful 1040STE tests under TOS 1.62, TOS 2.06, and EmuTOS with GemDrive and several ACSI drivers. TOS 1.04 or later is strongly recommended.

The upstream project describes hardware and software version 5.00 as finished and mature. Its release package contains files for ordering a compact board with assembly, but the builder must flash it initially with a 3.3 V-compatible USB-to-UART adapter and supply 5 V USB-C power, media, and an optional CR2032. Firmware 1.x, 2.x, and 3.0-or-later boards have different compatibility paths; the current compact design should use the matching current firmware. Lotharek's separate four-slot ACSI2STM Redux case design remained not yet available on 2026-07-27 and is not represented as a current assembled seller.

Maps an independent second gamepad button to Up while preserving the controller's normal directional Up input.

For this system (stated family): The seller states Atari ST family support and recommends the Slim connector for restricted clearance. Verify the exact controller and physical access.

MicroMiga listed the family from EUR 8.99 on 2026-07-30. The extracted variation table explicitly marked the short FAT version out of stock but did not expose a reliable stock state for the longer, slim machine-side version, so confirm the desired model before ordering. A controller needs genuinely independent fire buttons; duplicated or cloned fire buttons do not work for the remapping.

Adds a self-contained SAM2695 General MIDI sound module to an Atari ST-family computer's MIDI output.

For this system (bus/interface): The STE retains the ST MIDI interface. Connect MIDI OUT to GuMP, provide separate 5 V power, and use compatible Atari MIDI software.

The product page exposed a login-or-register-to-buy path on 2026-07-27. The box contains the cased module with an attached short MIDI cable, but the 5 V Micro-USB supply and speakers or headphones are separate. The seller identifies Atari ST use but does not prescribe player software; choose an Atari application that sends compatible MIDI data through MIDI OUT.

A newly made 1 MB SIMM for the Atari 520STE and 1040STE memory sockets.

For this system (exact model): The seller explicitly names the Atari 1040STE. Confirm the current SIMM population and install enough matching modules for the intended supported memory configuration.

The product page exposed a login-or-register-to-buy path on 2026-07-27. It explicitly names the Atari 520STE and 1040STE and loosely says it works in many more systems; only the two named computers are indexed here. Check the computer's existing SIMM population and desired total memory before ordering modules.

Connects a PS/2 mouse to Commodore, Amiga, Atari ST, and Atari 8-bit computers with host-specific mouse, joystick, paddle, and tablet modes.

For this system (stated family): Atari ST-family mode provides a conventional two-button mouse. Wheel and middle-button input are ignored.

The official shop listed immediate delivery from EUR 34.07 on 2026-07-30. Protovision listed five units from EUR 38, with the slim connector costing EUR 3 more. The slim version fits every supported computer; the wider screw-in version has documented clearance exclusions including the Amiga 600 and Atari 1200XL. A USB mouse works only if the mouse itself supports the PS/2 protocol through a passive adapter.

Adds an RTL8019AS Ethernet interface and an ISP1160 USB controller through the Atari cartridge port.

For this system (stated family): The seller explicitly supports Atari ST and STe systems. Netusbee plugs into the cartridge port and requires compatible Atari networking and USB software.

The product page exposed a login-or-register-to-buy path on 2026-07-27. Ethernet operation depends on Atari networking software and compatible drivers; the page supplies NetUSB02 version 5, STinG 1.26, EthernE, and utility downloads. Confirm software support for the particular USB device class before buying. The optional IRQ connection is not required for the basic cartridge-port installation.

Hosts USB HID mice, keyboards, joysticks, and gamepads on classic Amigas, with more limited C64 and Atari ST modes.

For this system (stated family): Current reseller documentation says Atari ST use requires additional adapters. Confirm the required DB9 extension and Atari firmware before ordering.

Amiga Shop listed Rys MKII in stock at EUR 44.95 with a 3-4 day shipping estimate on 2026-07-30; AMIGAstore separately listed EUR 31.95 but out of stock with restock T.B.A. Retro 7-bit publishes current Amiga firmware 0.16, manual 1.5, Windows flashing software, and RysWheel installers. Seller claims conflict about wireless mice, so buyers should assume a wired supported HID device unless Retro 7-bit confirms a specific receiver.

Adapts a USB mouse or digital USB joypad to supported Amiga, Atari ST and STE, or Commodore 64 GEOS mouse ports.

For this system (stated family): The seller explicitly names Atari STE systems. Select Atari ST mode during startup; analog joypad inputs are not supported.

The product page exposed a login-or-register-to-buy path on 2026-07-27. Only digital joypad input is supported; analog controls are not. TIKUS is distinct from the visually similar, non-upgradable Tank Mouse Kickstarter adapter. The revision sold since 2026-03-24 adds stored per-axis sensitivity configuration for Amiga and Atari mouse modes.

Connects USB HID mice, keyboards, joysticks, and gamepads to Commodore, Amiga, and Atari ST-family control ports.

For this system (stated family): Rev3 explicitly supports the Atari ST family, but Sordan requires a separately supplied DB9 extension or special adapter for the recessed port.

Sordan hosts current Rev3 and Micro Tom pages and a Rev3 manual, but neither product page exposed a price, stock value, or product-specific cart route on 2026-07-30. AMI64 listed TOM 2+ at GBP 40 but out of stock. TOM+ and TOM Rev2 are retained as older variants rather than presumed current products. USB peripherals may be hot-plugged, but the DB9 adapter must be connected only while the old computer is powered off. Device compatibility is not universal.

Replaces an Atari ACSI hard disk with SD or microSD media in external, direct-plug, or internal Mega ST-family forms.

For this system (stated family): The seller explicitly supports Atari STE systems through external ACSI. Choose a cased unit with the separate cable or the direct-plug Mini, provide 5 V power, and use an appropriate Atari hard-disk driver.

The internal, cased external, acrylic-case, and Mini pages exposed order paths on 2026-07-27. No form includes storage media. The current grey cased and internal revisions use USB-C, while the acrylic and Mini pages specify Micro-USB; a 5 V phone charger is not supplied. The cased units need a separately sold DB19-to-IDC20 ACSI cable, the Mini plugs directly into ACSI, and the internal unit needs a separately sold Mega ST or Mega STE adapter. The current cased page contains an older Micro-USB FAQ despite its revision notice saying USB-C. Older TOS versions can be slower or unsafe with DOS-compatible media, and some Atari DMA circuits or modern high-capacity card pairs need the documented troubleshooting or clock-capacitor fix. The optional DUCKBILL flasher requires a direct, bidirectional PC parallel port and Windows XP DOS console.
