Read and write your vintage floppy disks from your PC/Linux/Mac computer!
The Greaseweazle USB device lets you to connect an old floppy disk drive to your modern computer to read/write floppy disks from any system with Shugart standard drives (Amiga, Atari, Commodore, Amstrad, Sinclair, PC, CNC machines, musical instruments, etc).
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, ...). More information and documentation may be find at the Greaseweazle V4 Wiki.
