Greaseweazle 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, ...).

Comes with 3D printed white case (White PLA with 100% fill density). Case was designed by Tom Dalby.

Greaseweazle V4.1 is the very latest version, updating the V4 design with new features:

- Larger form factor with stronger mounting holes

- Modern USB-C connector

- Input protections (ESD, over-current)

- USB power isolation, allows Greaseweazle to be powered by external PSU along with drive(s)

Other 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 Keir Fraser before shipping

This listing is for the Greaseweazle V4.1 device + case only. You will additionally 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

Recommended host OS: Windows 10/11, Ubuntu Linux, macOS (recent versions). Most up-to-date versions of Linux distributions should also work (but less tested).

Package included:

- 1x Greaseweazle V4.1

- 1x Perfect fit White 3D Printed 2 parts case. You do not need any glue or screws, the case easily snaps together.
