Tag: floppy emulator

Uses an SD card to emulate Apple floppy drives and, on supported systems, HD20 or SmartPort hard disks.

The BMOW store showed the assembled Model C sold out at $109 on 2026-07-27. The separate Deluxe bundle is the same emulator packaged with accessories rather than a different product family. Check the direct product page for a restock.

Adds Wi-Fi networking and platform-specific peripheral emulation to several vintage computer families.

JCM showed 16 Apple II base units in stock on 2026-07-24. On 2026-07-27 Lotharek offered its assembled Atari Professional version both alone and with a dedicated SIO cable. It normally takes operating power from Atari SIO and uses USB-C for firmware flashing, although the page separately calls USB-C an optional power source for the 1200XL. The project also lists other small-batch vendors and open design files. Stock, enclosure, connection, power, and required interface hardware vary by computer.

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

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.

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

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.

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.

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.

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.

Emulates a Disk II floppy drive with disk images stored on an SD card.

The assembled package was out of stock on 2026-07-24. It requires a compatible Disk II interface card and does not replace that controller.

SD-card floppy emulator for Apple II-series computers using an Apple II Disk Interface Card.

Retro Electronics marked the assembled device out of stock on 2026-07-24. The SD card, 20-pin cable, and Apple II Disk Interface Card are not included.

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.

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.

Uses an SD card to emulate Apple II floppy and SmartPort devices from common floppy and hard-disk image formats.

The CT6502 shop marked wDrive out of stock on 2026-07-14. Check the direct product page for a restock.
