Re: Kryoflux with Macintosh 400K & 800K Floppy Drives

As an end user, I don’t harmonise. I accept that different drives give different results with different disks. I have a small collection of drives and although I have a favourite or two, those same drives have failed me terribly for certain Apple disks whereas a least favourite gave an almost flawle...

Re: Kryoflux with Macintosh 400K & 800K Floppy Drives

Oh, and a simplified perspective... the Kryoflux handles the “variable speed” aspect because it samples at a hardware level and decodes the signals (probably in software). It doesn’t care that the drive might be running at constant velocity because it is probably capable of sampling the signals at a...

Re: Kryoflux with Macintosh 400K & 800K Floppy Drives

I think you will find that the Kryoflux supports the Apple diskette media itself, but not the actual Apple hardware/drive. The Kryoflux doesn’t really care what it is reading; it is just picking up magnetic signals from the hardware it was designed to control. The Apple drives would require the desi...

Re: Dealing With Weak Sectors

Thinking about this for a moment, would a potential way for the KryoFlux to write weak sectors be to write transitioning 1's and 0's at a very significantly higher frequency than whatever the typical shortest transition is? That is assuming both the drive electronics and the board would be capable o...

Re: Apple II DOS 5.25 in. floppy disks

Probably something to do with "DOS 3.3 "high ASCII" text to Windows text" listed as a feature for the softwares built-in file viewer/converter.

Re: Apple II DOS 5.25 in. floppy disks

Short answer, it looks fine to me. The disk appears to contain some sort of text data, like something saved from some sort of word processor. There is also some assembly language style code as well (strangely saved in a binary format), but just small snippets of it. You can view these by opening the...

Re: DTC Scripting & IPF creation

I think you would have to assume it is still in the works (I think it has occasionally popped up in other posts).

Volunteer needed - Silicon Valley

I'm looking for a volunteer in or close to the Silicon Valley area to dump a few floppy disks (hopefully no more than two). The disk(s) in question is/are from a fairly rare Apple // title, which is essentially a classroom word processor. This particular title is not one that is readily available fo...

Re: Will KryoFlux help me? Will I be able to use this device?

I tend to think that if there were a good online video on Kryoflux usage, then it would be mentioned more often than not in these forums. So although I haven't actually checked, I'd say there probably aren't a lot in the way of videos for Kryoflux beginners. The official Kryoflux documentation does ...

Re: Apple II disk Grrr.....

Well according to that same article I linked to further above, a lot of the Infocom titles used almost the same types of copy protection schemes (or more correctly, the same cracking scheme could be used on multiple titles). So with the caveat that I haven't dumped any such copy protected Apple // f...
