KryoFlux - Write support is here and coming to you!

Post by mr.vince » Fri Nov 12, 2010 7:33 pm

We're closing the circle and we're wearing our roller skates. After nearly ten years of preserving software and getting it off the media, we're ready to write it back – thanks to KryoFlux even more precise and pristine than possible in the 1980s and 90s.

Making sure the hardware would function as expected (actually writing data to disk) was important to us and one of the reasons the first batch of KryoFlux boards got into production a bit late in early September. Now, two months later, we feel it's time to let you know that we're testing things internally and will move on to closed beta in early December. Our plan is to roll out our DiskTool Console (DTC) application with write support as a Christmas present to all our early birds that were willing to invest into KryoFlux knowing that it was read-only for the time being. Thank you all for your trust and support! It is very much appreciated by the whole team. We mean it!

We will be supporting IPF files at first (yes, including all those weird and nasty custom formats) and add standard sector writing (.ADF, .D64., .IMG etc.) very shortly after. Why not start freestyle and then continue with the compulsory exercise?

I'd like to point out that while we are pulling all strings to make it happen, we're still commited to quality. Therefore we will not push out something that's known to be problematic but could be made better in just a few days.. And please be aware: Writing precise patterns to disk requires a quality floppy disk drive. We have found that some drives have a terrible amount of unpredictable jitter that can't be compensated for in software. Therefore... if you want to drive at 250km/h, make sure you have the right tyres!

What's the best story without pictures? Here you go:
kf_cta_jitter.png
kf_cta_jitter.png (14.95 KiB) Viewed 10230 times
This is a standard DD disk, AmigaDOS format, and it's showing some jitter that is pretty standard given the precision home computer equipment can achieve when writing disks. Note the track (Cylinder 65.0) is 12659 bytes in size.
kf_cta_longtrack.png
kf_cta_longtrack.png (14.35 KiB) Viewed 10230 times
This is a so called long track (Cylinder 0.0: 13938 bytes in size), written with KryoFlux. Please note the very precise density line, which only shows a small notch (which btw is the write splice). The rest of the disk is untouched and was formatted in an Amiga.
kf_cta_sync.png
kf_cta_sync.png (22.9 KiB) Viewed 10230 times
In case you want to annoy a copy program like X-Copy, try a track like this. It's very precisely filled with $4489 only, the sync word used by MFM recording.

Stay tuned for updates!

Wow :-)

btw, what drive can I get that will be reliable (top 1 or 2 floppy drives you recommend) that I can restore any broken original disk?

I need 2 floppies anyway,so if you can get hold of one I'll buy it outright, thanks!

Hi. This looks great and I can't wait to try it. How's it going and when do you think there will be a beta of the software available? :)

We in fact have done lots of testing, but real progress was delayed a bit due to high load in "real life". :)

I can only estimate, "soon" pretty much says it and it will be in February (until something else happens that further delays it).

We want to make sure it's a "one click" experience, at least for clean masters (e.g. IPF). We don't like the approach of fiddling and trying that comes with other, older solutions.

This does not mean writing is easy peasy in general, but we want to prepare it as good as possible so using it does not require deeper knowledge.

Any news on this highly awaited feature? :D

For myself, I would love to start with a "lot of keyboard types" writing solution instead of the "one click" one 8-)

I understand this is exciting and very tempting. I also is for us. But there's danger invovled in this. People will start using it the moment it's out. Creating new disks with erroneous data could result in people sharing broken stuff, playing broken images (just to find out on the last level) etc.

Besides, one click is not only a philosophy, it's got to be this way. Otherwise we would require knowledge that's not there (at least for many users). I remember very well how easy it was to use a parameter copier back in the day. On the other hand, supporting generic tools like X-Copy and Cyclone costs hours of support. We want to make sure that if we have enough information (e.g. IPF files), we use it with as little user interaction as possible.

We also made sure we iron out all bugs that can be ironed out before release. People that still remember the Cyclone20 project might remember that some mysterious bug popped up that from time to time crashed the board. The bug was never found and Rich Aplin lost interest in development. We found several of these show stoppers, all due to bugs in hard- (ATMEL) and software (ATMEL SDK). This required lots of testing, in some cases running 999 consecutive write and readback cycles. We have not seen a (not expected) crash in weeks now so... I am not going to give an estimate but I am pretty optimistic.

agreed, it's like being part of the process ;-)

awesome work people!

I have not heard any complaints about latest beta, but we found bugs in Mac and Linux port that have already been fixed. These will be included in the next release.

Good to know as I prefer to use Linux.
