Various versions of the Greaseweazle adapter have been around for a long time. It's a floppy drive interface similar to the Kryoflux I've owned for years. It's original idea was to read and write Amiga floppy disks on a PC.

V4 of the Greaseweazle has seen a lot of development. It can not read and write multiple disk formats across a lot more formats and systems. It also has a new ability, directly supported by WinUAE, you can boot and load Amiga disk directly in WinUAE!

The best news however is the price. Just £20.99.

Here's the official information:

Greaseweazle v4 allows versatile floppy drive control over USB. By extracting the raw flux transitions from a drive, any disk format can be captured and analyzed – PC, Amiga, Amstrad, PDP-11, musical instruments, industrial equipment, and more. The Greaseweazle also supports writing to floppy disks, from a range of image file formats including those commonly used for online preservation (ADF, IPF, DSK, IMG, HFE, …).

Greaseweazle V4 is the latest version, updated for mass production and with the following features:

  • Reads and writes 3″, 3.5″, 5.25″, 8″ disks (with suitable drive and cable)
  • Buffered outputs, for communicating with older 5.25″ and 8″ disk drives
  • Integrated power connector for directly powering most 3.5″ disk drives
  • Write-enable jumper can be removed for safer preservation of precious vintage disks
  • Supports flippy-modded 5.25″ drives
  • Supports Disk-Change detection as used by Rob Smith’s integration into the WinUAE Amiga emulator
  • 3 user-definable outputs (eg. 8″ interface REDWC signal)
  • 100% factory tested, and tested again by me before shipping

This listing is for the Greaseweazle V4 device only. To use it you will require:

  • A disk drive (for example a PC 3.5″ or 5.25″ drive)
  • A floppy ribbon cable (typically you want a standard PC cable with ‘twist’ on pins 10-16, to communicate with a PC floppy drive)
  • Floppy drive power cable, or power supply

This is built by Zero Flux Development.
