Greaseweazle allows versatile floppy drive control over USB. Read and write your vintage floppy disks from your PC/Linux/Mac computer. This 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, Atarí, Commodore, Amstrad, Sinclair, PC, CNC machines, musical instruments, industrial equipment, and more.)

By extracting the raw flux transitions from a drive, any disk format can be captured and analyzed. 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 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)
100% factory tested, and tested again by me before shipping

"What if documentation really lived in the code?

Docstrings are already there. If some narrative glued them together, we'd be able develop and explore the code along with the documentation due to their physical proximity.

With the simplistic tools provided, one may emphasize the narrative as with Literate Programming, but documentation is generated from code, not vice versa, and there is no support for chunking.

Code is first, code must look pretty, documentation is code."
