Full details can be found at http://www.kryoflux.com/

Preorders for the board are now open with the board costing €89 and a premium bundle consisting of the board, floppy drive cable, USB cable and PSU for €99. Registration of interest in purchasing one is on their site.

More details:

KryoFlux is a USB-based floppy controller designed specifically for reliability, precision, and getting low-level reads suitable for software preservation.

Main Features

  • Read at lowest level possible - precisely sampling the magnetic flux transition timing. Custom formats? Copy protection? Encodings? KryoFlux doesn't care!
  • Save as raw stream, or export to common sector formats supporting: Acorn Electron, Apple, Amstrad CPC, Archimedes, Atari 8-bit, Atari ST, BBC, Commodore 64, Commodore Amiga, MSX, IBM PC, PC-8801, Sam Coupe, Spectrum, and many, many others.
  • Parallel export support. E.g. An Amiga/ST dual format disk can be written as raw stream, an ADF and an ST file, all at the same time during a single disk capture.
  • Intelligent software allows production of sector images for virtually all normal disks for systems containing a generic FM or MFM floppy controller. All those weird synthesiser sample disk formats should work right out of the box.
  • Read variable rate "zoned CAV" disks in a normal fixed rate drive.
  • RoHS and WEEE compliant.
  • High quality immersion gold coated boards produced in cooperation with, and assembled by, Olimex Ltd.



Technical Specs

  • Compatible with USB 1.0 (full-speed) and USB 2.0 (high-speed) ports.
  • Powered by USB interface (approx. up to 300mA). Drive requires it's own power.
  • Shugart (with extensions) drive interface. 34-pin dual-row header connector.
  • Developed with 3.5" Samsung SFD-321 and 5.25" Newtronics D509 drives and compatibles. Other types of drives and media (such as 3") currently under investigation.
  • Connection of two drives supported using a dual floppy cable, one can be accessed at a time.


Notes

  • Host software is currently Windows only (XP, Vista, Windows 7 in 32 and 64-bit flavours). Ports will follow.
  • Hardware is write-capable, but write support has not been implemented in the software yet. This is intended to come later.
  • Open file format, DRAFT, used to store raw flux reversal timing information - in development.
  • Software completely free for private, non-commercial use.
  • Easy to use graphical user interface - in development.
