Greaseweazle V4.1


Available Options
Data Ribbon and Power Cable Kit:

Read and write Amiga format floppy disks using a PC or Mac !
Plug a floppy disk drive into Greaseweazle and then connect it to a USB port. Use the software to read or write an Amiga format floppy disk - it even supports ADF files.
This adapter is great for backing up Amiga floppies to image files.
Greaseweazle 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, ...).
WinUAE supports Greaseweazle in beta currently: this lets you insert/eject real Amiga floppy disks and they appear on the Workbench. Read and write to them as if you were using them on a real Amiga.
Greaseweazle V4.1 is the latest version 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 floppy-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)
  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)
  100% factory tested before shipping
  2-page printed manual with online Wiki support pages
