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.

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.
