Atari 1040ST upgrades

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.

Replaces supported 34-pin floppy drives with disk images stored on a USB flash drive.

For this system (stated family): FlashFloppy explicitly supports the Atari ST family. Its guide says no special configuration is required: use the default Shugart interface and normally place the drive-select jumper at S0.

FlashFloppy directly supports most SFR-prefix Goteks with a 34-pin header. Do not buy a UFA-prefix USB-floppy model; 26-pin DU26 and TU26 models require modification, and the project recommends avoiding the FDD-UDD U144K. Gotek's maker site accepts only wholesale orders of at least ten, while the linked specialty catalog lists several individually priced, configured units. Confirm the microcontroller, installed firmware, front-panel fit, cable orientation, power, and host-specific jumpers before installation. Initial FlashFloppy programming may require a boot jumper and a USB programming cable or USB-TTL adapter.

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

For this system (bus/interface): Connect the attached MIDI IN cable to the computer's MIDI OUT, provide 5 V Micro-USB power, and use Atari software that sends General MIDI-compatible data.

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.

Replaces an Atari ST or Mega ST memory subsystem with a 4 MB expansion and a motherboard-specific adapter.

For this system (stated family): The seller explicitly includes Atari ST, STF, and STFM computers. Identify the motherboard revision and whether the MMU and Shifter are socketed, then buy the matching adapter and follow the original-RAM disable and signal-wiring procedure.

The Heron board and three current adapters exposed order paths on 2026-07-27. A complete installation requires the Heron plus either the C070789-001 Revision F adapter, the C070523-001 Revision D adapter, or the universal socketed-MMU adapter. C070859-001 Revision 2.0 and C103414-001 adapters were still described as in development. The Shifter must be socketed or desoldered, the original RAM must be disabled, and A9 and WE wires must be connected. This is a skilled mains-exposed internal installation; disconnect power and choose the exact motherboard adapter before ordering.

Replaces compatible 34-pin floppy drives with read/write disk images on SD or SDHC media.

For this system (stated family): The official compatibility material names the Atari ST family. Use the documented Shugart jumper arrangement and confirm cable orientation, 5 V power, mounting, and access to the controls and display.

All fourteen Rev C, Rev F, and MAX hardware variants exposed current login-or-register-to-buy paths on 2026-07-27. Rev C and Rev F use a standard floppy 5 V supply; the manual specifies at least 400 mA and says the 12 V line is unused. MAX accepts either 5 V over Micro-USB or 7-12 V center-positive DC power. Verify pin 1, drive-select jumpers, cable twists, voltage, and physical fit before connection: some computers reverse the usual 5 V and 12 V floppy-power positions, and incorrect power can damage both emulator and host. The firmware reads and writes supported images but does not reproduce variable-bit-rate protection completely; IPF and STX support is partial.

Adds read/write SD floppy emulation in compact 34-pin and 26-pin FPC forms.

For this system (stated family): Lotharek lists the Atari ST among tested hosts, and HxC officially supports the ST family. Select the connector variant that matches the installation and confirm cable orientation, drive select, 5 V power, mounting, and control access.

All five Lotharek Slim variants exposed current login-or-register-to-buy paths on 2026-07-27. Choose the 34-pin HE10 or 1 mm 26-pin FPC version for the host; the 26-pin form requires the manual's ID0A setting. Supply regulated 5 V and verify the host connector, voltage, pin 1, drive select, cable, and mounting before connection. The manual specifies at least 300 mA and a 500 mA maximum figure. The firmware reads and writes supported images but does not reproduce variable-bit-rate protection completely; IPF and STX support is partial.

Streams read-only floppy images from a modern USB host to compatible 34-pin drives or an Amiga external-floppy adapter.

For this system (stated family): The USB HxC documentation names the Atari ST family. Confirm Shugart selection, pin 1, mounting, and access to the modern USB host; disconnect USB before changing the floppy-side cable.

The standalone unit, cable set, and Ami2PC bundle exposed current login-or-register-to-buy paths on 2026-07-27. The official HxC home page and release notes show that the software project remains active in 2026. The unit needs a modern computer running the HxC host software and emulates disks read-only. The standalone set includes a 40 cm floppy ribbon and USB A-to-B cable; Ami2PC instead adds the Amiga external-floppy adapter. Never connect or disconnect the 34-pin or Amiga-side cable while USB is attached; disconnect USB first. Ami2PC can use Amiga disk-copy software to write a real disk in DF0 from an emulated DF1. Its early-boot workflow needs Kickstart 2.0 or newer. The seller still does not identify which oldest Amigas need its unspecified modification, so do not rely on early-model boot support without separate instructions.

Adds about 1.7 meters of reach between a compatible nine-pin controller and its vintage computer.

For this system (stated family): AutumnHippo lists the Atari ST family. The cable does not make controllers from other nine-pin systems electrically or logically compatible.

AutumnHippo exposed an add-to-cart route at USD 7 on 2026-07-30. Protovision separately showed ten joystick extension cables in stock at EUR 10 with a one- to two-week shipping estimate. The exact long and short products pictured by the C64 OS guide are not identified, so the catalog keeps current length and seller variants together.

Provides a new 1.7-meter nine-conductor lead for repairing compatible vintage joysticks and controllers.

For this system (stated family): The seller lists Atari ST controllers. Shared connector shape alone does not make a controller interchangeable with the other named systems.

AutumnHippo exposed an add-to-cart route at USD 7 on 2026-07-30. Basic soldering is required. Trace the existing cable or controller circuit before removal: the seller explicitly warns that wire colors can differ and that systems sharing a nine-pin plug do not necessarily share controller wiring.

Converts composite, S-Video, RGB, RGBI, and VGA-family retro signals to simultaneous digital and analog DVI-I output.

For this system (stated family): The recognized-mode list includes Atari ST PAL, NTSC, and high-resolution timings. Use the correct ST-to-SCART or ST-to-VGA cable for the desired mode and confirm the destination display supports its vertical refresh rate.

The European SCART and Japanese JP21 Revision B pages exposed login-or-register-to-buy paths on 2026-07-27. Never connect an EU SCART cable to the JP21 version: the seller says the different pinout can damage the device. The newest dated hardware announcement says units made since June 2025 have a larger OLED and USB-C power, but an older section still says Micro-USB. Human review found no package clarification, so confirm the connector, power requirement, and included USB items with the seller. A DVI-to-HDMI cable and source-system cables are sold separately. Medusa line-doubles when needed but does not change vertical refresh rate, so the destination display must accept the resulting 50 or 60 Hz signal and may blank briefly when the source changes resolution. Install only firmware matching the hardware revision.

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.

Converts a PS/2 mouse into Atari 8-bit or Atari ST quadrature mouse signals.

For this system (stated family): The project explicitly produces Atari ST quadrature mouse output. A build still requires a programmed PIC, correct port wiring, and a PS/2-protocol mouse.

The maker publishes beta firmware, source, a pinout, and programming files but not a finished adapter PCB on this page. A build requires a programmed PIC16F1847 and suitable wiring or an enclosure. For an internal installation, connect behind the computer's in-line joystick resistors so a plugged-in joystick cannot directly short the PIC outputs. USB mice work only when they also implement the PS/2 protocol.

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 or ROM port; install a compatible Ethernet stack and device drivers before expecting network or USB functions.

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.

Connects a PS/2-compatible mouse to an Atari 8-bit or Atari ST-family computer.

For this system (stated family): The ST adapter page explicitly supports the Atari ST, Mega ST, STe, and Mega STe families. Confirm that a selected mouse implements the PS/2 protocol.

Both storefront collections marked their matching adapter sold out on 2026-07-24. A USB mouse works only if it also supports the PS/2 protocol and is used with a suitable passive USB-to-PS/2 adapter.

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 device provides an Atari ST mouse-emulation mode. Select that mode during startup and use a supported wired or wireless USB mouse, or a digital USB joypad.

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): Use an external cased or Mini UltraSatan through the ACSI hard-disk port. The cased form needs the separate DB19-to-IDC20 cable; Mini plugs in directly. Prefer a current TOS and test the computer's DMA path before trusting important data.

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.

Connects modern Bluetooth gamepads and, on selected models, mice to Commodore, Amiga, and Atari computers.

For this system (exact model): The maker explicitly lists the Atari 1040ST. Extension cables are required because the control-port spacing differs, and the appropriate variants support Atari ST mouse emulation and extra buttons.

The official C64, A500, and 800XL Tindie pages were out of stock on 2026-07-30, although the project marks those models active and supported. CBMretro had equivalent cased C64/C128 and A500/A1200 hardware available at EUR 41.90; the original designer does not support third-party builds. Open hardware, firmware, and documentation remain available. The guide's original Unijoysticle tile is folded here as the retired WiFi predecessor: it needed a separately powered ESP8266 receiver and phone or desktop client, unlike the Bluetooth successor.

Connects supported vintage computers to Wi-Fi BBSes through an RS-232 serial port.

For this system (stated family): The vendor says the modem was tested with all Atari ST models. The WiModem232 Pro has a female DB25 connector, so use the correct ST serial cable or adapter and provide external 5 V power.

The current Pro V2 model was in stock on 2026-07-30. It has a female DB25 connector, a color TFT screen, a printed case, faster interface buffers, and signal-state LEDs. It needs an external 5 V micro-USB supply, and the host may also need a gender changer, DB9 adapter, or correctly wired computer-specific serial cable. The older display-free and OLED WiModem232 models are discontinued and replaced by this version.
