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.

Packages 586220, 785260, and related service ROMs as current single-ROM and switchable multi-ROM diagnostic cartridges.

Current choices on 2026-07-30 included Retro Rewind's in-stock CAD 22 C64 586220++ and C128 785260 cartridges, its CAD 40 four-ROM C64 cartridge with a two- to three-day lead time, AMI64's GBP 19 eight-ROM C64 cartridge with an approximately seven-day lead time, ogHugo's USD 26.99 before-tax two-sided C64 cartridge with an Add to Cart path, Retro-Updates' EUR 17.99 two-sided C64 cartridge, and C64iSTANBUL's orderable two-ROM PCB with current fabrication files. DIY8BIT's USD 22.95 781220/586220 cartridge was unavailable while its Etsy shop was on break. Retro Rewind's older Dual Diag route now displays the store's not-found page. ROM sets and model support differ by variant; a full port test requires a separately bought or built harness.

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.

Cartridge fast loader for a Commodore 64 or 128 using an existing SD2IEC device or Commodore 1541-family disk drive.

TFW8b exposed an active product page with selectable options on 2026-07-27. This is an accelerator for an existing storage device, not storage by itself. Loading speed and compatibility depend on the program and attached drive.

Socketed rotary-switch ROM board sold with either eight C64 KERNALs or a mixed C64 and 1541 diagnostic set.

Retro Electronics listed two KERNAL-set boards and three mixed repair-set boards in stock on 2026-07-25. Both arrive preprogrammed. The pages name original and third-party ROM images but do not document their licensing; verify that you are entitled to use every selected image.

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.

Adds a live track, density, write-protect, motor, and sync display to supported Commodore floppy drives.

The standard and 6522-included variants were both out of stock on 2026-07-24. The 1541-II and 1571 require the special version with a 6522 VIA soldered to the tracker board; the standard version will not work in those drives. Installation can require desoldering the original VIA, fitting a socket, and mounting the display and button externally.

Installs inside supported Commodore floppy drives to duplicate protected disks and add disk utilities.

Both assembled variants were out of stock on 2026-07-24. Each listing includes a 40-pin socket and version 6.0 software on two 5.25-inch disks. Some drives require desoldering the 6502 and installing a socket, so identify the drive model and board revision before ordering or installing.
