I have two 3.5 floppies in my machine and a 5.25

I is teh old skool.

Be my guest and assemble KryoFlux internally. We still won't go the stony road and produce a pass-through feature for the floppy drive. :-)

Oh crap!
That's what happens if one "just" tries to help. Very embarrassing...

Thanks for the clarification.

papa_november · 11 March 2010, 21:22

If a pass-through is out of the question, could it be made to simulate an ordinary USB floppy drive?

IFW · 11 March 2010, 21:27

Could you be more specific please: simulate what exactly? There are many possibilities...

papa_november · 11 March 2010, 23:53

Can it show up as a USB floppy drive in Windows and be booted off of on systems that support booting off of USB disk drives?

That's probably a tall order, though. Probably unnecessary, too, given that I imagine the final KryoFlux board would be orders of magnitude faster than a contemporary floppy controller.

I asked about the combo floppy drives earlier because it's much easier to find an external case with one 5.25 bay than it is to find one with two 5.25 bays or one 5.25 and one 3.5.

There seems to be 3 common models: one made by Epson, one made by NEC and one made by TEAC. They all seem to be a PC-98-style 5.25 drive bolted to a laptop-style 3.5 drive. I have the TEAC and the NEC models on hand and the NEC appears to have a movable optical track 0 sensor while the TEAC does not. Neither have much space for the head to move much farther back. On average, how far would it have to move to reach track -8?

None of my X68000 disks are original, but I am definitely planning on acquiring a few original disks in the future, and I'll alert anyone who has them that you need some.

Sorry, no. The device is for dumping with the dumping software only. Or writing, as soon as this gets implemented.

What's the timeframe for writing support and is it possible to directly mount a stream file as an ADF or can it be converted?

The timeframe varies... we want to get rock solid reading and hardware ready... This will cost money so... will depend on donations coming in...

Stream files need to be converted. Stream files are just flux changes which need to be interpreted. It's better, easier and safer writing this to a file than doing this in a separate thread in the background.

IFW · 13 March 2010, 22:56

Yes, it's possible to do on the fly conversion, but probably you'd need something much simpler than the analysis done by KF to make good reads, or run it on say a separate hardware thread of your cpu - if you want it "real time".

mr.vince · 14 March 2010, 10:46

My main concern is/was that when doing this in real time, you are wasting processing power over and over again for decoding. If you do it to a file, you have all resources for e.g. the "real" emulation.

Loedown · 14 March 2010, 13:06

Gentlemen, I am happy to write a raw file to the PC, just want to know if it can be converted to an ADF from there, not in real time.

IFW · 14 March 2010, 14:04

Sure, if you read the KF manual you will find that you can use stream files like if you were just reading data from a KF board.
You have to select the input device to be stream files, using -m1, and define the input the usual way like you would for creating the files e.g. -fmystreamfiles/teststream -i0

KryoFlux 1.0 Beta 4 is out!

http://www.softpres.org/news:2010-03-16

18 March 2010, 14:57

How about adding support so the device can support reading and writing of FDI images?

FDI image Specs http://www.oldskool.org/disk2fdi/files/FDISPEC.pdf

Is there any specifications writen about the "KryoFlux stream files" file format that I can read?

Is there any specification written about the "IPF" file format that I can read?

How about adding support for reading tapes via some sort of Schmitt trigger set-up like what already present inside a C64 data recorder?

Thanks

hi,

there are reasons why we have chosen to develop kryoflux instead of using already available technology. the same applies to fdi. stream files are just a temporary solution, with draft replacing them. draft offers the same functionality at reduced file size and other things. the draft format is fully open, therefore detailed docs will be available.

at the time, access to ipf files is only available through the capslib available for download at softpres.org. the format is very complex (scripting etc.) and advanced and we have chosen not to publish anything unless we can make sure the documention is really comprehensive and failsafe. it would also mean people would have to develop an analyser which makes this option even more complex.

we have no plans at the time for tape ingestion. the setup for this is very easy and there are other projects caring about tape ingestion. we have limited manpower, so we have chosen to focus on floppy based solutions.

Computer developers and well written documentation, I thought the two were mutually exclusive

I think some sort of proper rendering tool should be eventually made available that can write a stream file back into and ADF or D64, better to stick to known formats IMHO if possible?

Slayer · 21 March 2010, 06:18

Well I must say things have moved along quite nicely :-)

I have hundreds of original disks and one day plan to go through them all and repair those that are no longer valid...

I'm not in much of a hurry but will want to buy the finished product... probably 2 to be sure...

Thanks for pursuing this!

Actually, for C64/128 materials, especially the copy protected stuff, the G64 format is better. It produces non-standard tracks much more accurately. Though the D64 is smaller, and would be preferable for disks that have no on disk copy protection.

I also, cannot wait for a final release on the HW, been trying to save aside money just to get it. Though I hope I can get one with a good 3.5" drive as well as an appropriately altered 5.25" drive attached, and packaged up in a nice case with power adapter (I assume one will be needed,) and USB port. Wouldn't mind any other options that might be available as well. Looking at the designes, it looks like an SMD or some other memory card slot is also on the board.

Please keep us informed about anyone that starts producing for-sale units

Thank you.
