That is a great idea on both counts. We could have a list on the website, with compatibility reports sent in by users.Quote:

I do know a few different people who might be interested. However they would need to know the full details of the planned license and certification first to see if it was worth their while.
The Kryoflux boards are finally going into production and are in Public Beta testing.
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.http://www.kryoflux.com/kf_features_thumb.png Prototype FeaturesMain Featureshttp://www.kryoflux.com/kf_back_thumb.png Prototype Rear
- 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.
- More details available here.
- Please feel free to contact us here if you have any questions.

Excellent!! And at only...£2.37 cheaper than a Catweasel Mk4+... :o
Wait for the Euro to go weak again!!
It is a bit of a dilemma isn't it. Get a Catweasel MK4 Plus, or this new KryoFlux. The 2 are very different pieces of hardware.
I have the feeling the retro community might take to the KryoFlux a lot more than the Catweasel and start to explore developing the hardware and software further. If that happens then it could become very popular within the whole retro scene.
I'd rather have a Kryoflux than a Catweasel in my PC - simply because I can plug it in when I need it (so it's not taking up resources or drive names when I'm not using it, and I use my PC a LOT more than when I would be using it for ripping my PD disks), and gives a much better resulting disk image including the copy protection etc. I would also sell it once I had ripped all of my disks.
It made me laugh watching the promo video which said "other solutions utilise expensive PCI cards to interface a simple floppy drive to a computer"...yes, and the Kryoflux costs the same to interface a simple floppy drive to a computer...
With the older Catweasel models, the drivers were started with the startup of your PC, the MkIV drivers are only started when you launch the application, thus terminated when closing it.Quote:

Yes, sadly we underestimated how much everything would cost. A low-volume manufacturing run, RoHS compliance, WEEE compliance (expensive!), postage, purchasing multiple production prototype boards for testing (which are hand made) - obviously hardware you can't correct later. That is not including all the other little costs and the time we have put into all this.
Still, it's all been very much worth it. We're really excited about how things are progressing. Hopefully well have more news soon!
Definitely look forward to more information as you get it.
And don't worry, we very much appreciate that any hardware made for the retro scene is always going to cost more than mass produced hardware. Limited production runs and more exotic components will always push the price up, but the retro scene is not about making money, but enjoying the great old systems, and most still within the scene are willing to may a premium to obtain the custom make hardware to expand and improve their passion.
Keep up the great work, and I look forward to the next news update on your progress.
Hi, I intended to post more information and updates here, but as a new user I can't post links so... my first topic is a bit useless.

Hi, there has been so much progress you have not seen since it was moved to a dedicated site & forums:
http://www.kryoflux.com
http://forum.kryoflux.com
It's working fine so far with many 3", 3.5" and 5.25" drives. More drives are under investigation.
We currently do have support for FM, MFM (this includes IBM PC, Atari ST and many others, including many musical instruments), AmigaDOS, C64, many Apple formats and Emulator I+II from E-MU Systems. More formats will be added.
One key feature is the option to do forensic dumps regardless of the format, so even alien formats can be read and archived and then processed later.
Writing, as Richard wrote, does work, we have tested the hardware and can confirm it can write data to disk. We just have not finished this part of the software, because other features (ports, GUI) seemed more important and we all do work full time besides doing this.
The software, including a GUI, is available for Windows (and yes, we *do* support 64bit :p) and Linux, with a Mac port in production. The software is completely free for private, non-commercial use = the community gets it for free. Pro-users need to get a commercial licence for it. These will help to fund further development.
Here's a quick overview:
http://www.youtube.com/watch?v=GjEPo2pRGjY
Basic (older) schematics are included with the software, and we plan to release the current schematics (which do use bus drivers) with the next release.
We also have pre-built boards available, so you don't have to etch your own boards and start soldering. Many people that originally intended to built their own decided to go for a ready-made product when they saw the pitch used here (the components are *really* small).
Anyway, if you want a board, you can get them here: http://webstore.kryoflux.com/catalog

Thank you for the update Chris. (btw, are the same person as the fiath account who posted above in this thread? or a different member of this project?)
It is great to see you have continued working hard on this project and it has renewed my interest. I will definitely be looking at the new site when i get time. :)
