Greaseweazle v4.1 Amiga Amstrad, Spectrum
Greaseweazle V4.1 USB Floppy Adapter Flux Reader Writer

Greaseweazle v4.1 allows versatile floppy drive control over USB. By extracting the raw flux transitions from a drive, any disk format can be captured and analysed - 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 V4.1 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 V4.1 device only. And does not include which 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
