Upgrades an Atari 1050 disk drive for divisor-6 high speed, 180 KB per side, and flashable firmware slots.

Lotharek marks 1050E discontinued. The seller calls installation solderless, but it still requires opening the drive, removing three chips, moving the 6507 CPU, and preserving socket orientation. Confirm that a used kit is complete, that all original chips and sockets are healthy, and that suitable 1050E firmware and host software are available.

Runs a cartridge-resident suite of health, speed, alignment, sector, and command tools for 1541-family floppy drives.

Protovision listed 22 units at EUR 25 with a one- to two-week shipping estimate on 2026-07-30. Jani also publishes free cartridge images for device 8 and device 9. The software alignment display is a health indicator, not a substitute for a factory analog alignment disk and oscilloscope.

Rebuilds the electronics inside an original Disk II drive with a cleaner analog path, keyed cabling, write protection, and easier head access.

CT6502 offered the two-board set for direct ordering on 2026-07-24. The boards are not sold separately.

Period SIO floppy drive adds double-sided, double-density 5.25-inch storage and faster double-density transfers to Atari 8-bit computers.

Find a complete used drive with the correct AC adapter and SIO cable. The bundled DOS 2.5 supports single and enhanced density but not the XF551's full double-sided, double-density capacity; use DOS XE or compatible third-party software for that mode. Most drives use a Mitsumi mechanism with a rectangular activity LED, while later Chinon examples have a round LED and stricter flippy-disk limitations. The 300 RPM mechanism can also conflict with a small amount of speed-sensitive copy protection.

A compact universal-input replacement supply for Commodore 1541-II and 1581 floppy drives.

Retro Lemon exposed a live GBP 27.50 listing with free delivery on 2026-07-30, but the extracted page did not expose an unambiguous stock or Add to Cart state. Confirm availability and delivery region before ordering. The page does not publish over-voltage protection, fusing, isolation, connector pinout, or serviceability details.

6522 VIA interposer that changes a Commodore 1541 drive between device IDs 8 through 11 without cutting its original jumpers.

TheRetroChannel listed five boards in stock on Lectronz on 2026-07-27. External wiring and DIP switches are not included. A drive with a soldered 6522 first needs the chip desoldered and a socket installed; an external switch may require case cutting.

Connects a standard 3.5-inch PC floppy mechanism to a Commodore 1581 disk drive.

Retro Electronics listed two adapters in stock on 2026-07-25. Only the adapter is supplied; cables and the replacement floppy mechanism are not included.

Assembled replica controller board for building a Commodore 1581-compatible 3.5-inch disk drive.

Retro Electronics listed the fully assembled and tested board out of stock on 2026-07-25. Only the controller PCB is supplied.

Builds a Commodore 1581-compatible IEC disk drive from CS/A65 processor and floppy-interface cards.

No assembled seller or current PCB supplier was verified. A build needs PETCPU and DRVIO cards, a backplane, components, a suitable 720 KB drive mechanism, a legal 1581 ROM image, power, cabling, and an enclosure. DRVIO revision 1.1A is marked okay and was tested with double-density PC drives; PETCPU revision 1.1B publishes board files but its layout is marked untested. High-density operation can overclock the WD1772 and is not the documented 1581 configuration.

Generates the Amiga READY signal so a compatible 3.5-inch PC floppy mechanism can replace an Amiga drive.

The product exposed a login-or-register-to-buy path on 2026-07-27 and was tested with more than forty mechanisms from several manufacturers. It operates only in double-density mode. Some Alps and Mitsumi drives place their power connector where DriveRDY physically overlaps it. Human review confirms the simple inline fit but supplies no exact Amiga model, cable-orientation, drive-select, or chassis evidence, so the existing interface-based relationships remain conditional.

A current replacement supply for Commodore 1541-II and 1581 drives, offered in Basic, adjustable, and higher-capacity PRO versions.

Electroware listed the family from EUR 36.99 with dispatch in three to five days on 2026-07-30. Select the correct mains option and exact Basic, Adjust, or PRO configuration. Only the PRO description permits two drives, and the published 5 VDC and 12 VDC capacities differ from C64Lover's separately indexed supply.

A single replacement supply that powers a C64 or later VIC-20 together with a 1541-II or 1581 floppy drive.

Electroware listed the twelfth-revision supply at EUR 68.99 with dispatch in three to five days on 2026-07-30. Regional mains configurations and an optional Adjust and Protect 5 V trim are offered. C128 use requires a separate C64-to-C128 adapter; choose and verify that adapter rather than connecting the C64 lead directly.

Upgrades an Atari 1050 disk drive with true double density, faster backup operations, and protected-disk support.

The 5cfab stand-alone Happy Warp 1050 v7.1 reproduction reported two boards in stock on 2026-07-27; Atarimax still provided a conditional add-on route on 2026-07-25. The 5cfab board includes its CPU and needs no soldering, but installation still requires opening the drive and carefully replacing internal hardware. Align the board's crystal with its clearance hole. The Atarimax guide also warns about static, alignment, and orientation.

Adapts the powered 34-pin floppy cable in compatible IBM PS/2 systems for a standard floppy drive or Gotek.

Retro Electronics listed three assembled adapters in stock on 2026-07-25.

Protected dual-output supplies for a C64 or later VIC-20 and a 1541-II, 1571-II, or 1581 floppy drive.

Keelog listed current regional RetroPower, Classic, and Modern configurations on 2026-07-30. The representative RetroPower US model was USD 89.99 or EUR 78.99 and included its device cable. Select the correct 120 V or 230 V version and regional plug. The current RetroPower page calls that enclosure the successor to the earlier Classic and Modern styles.

Assembly kit that adds a numeric track or sector display to supported Commodore floppy drives.

Commodore4ever and Protovision both exposed current-priced product pages on 2026-07-27, but neither extraction exposed an unambiguous Add to Cart control. Confirm availability before ordering. The kit requires through-hole assembly, display wiring, and internal drive installation; stacked boards or sockets can create clearance problems.
