KryoFlux

Ordinary floppy drives read already-decoded bytes and miss anything that departs from the norm — copy protection, exotic formats, worn disks. KryoFlux (2011, from the Software Preservation Society) instead reads the raw flux transitions on the surface, timestamp by timestamp, and stores them as "stream" files that can be decoded into any 8- or 16-bit format afterwards.

That made the board a standard tool for serious floppy archiving, alongside the older Catweasel and the open, cheaper Greaseweazle. Anyone who wants to play rather than preserve tends to reach for a Gotek instead.
