Re: First attempts at reading Apple II flippy

I don't have flippy experience, but by the looks of your screenshots there it would seem that there is a track alignment problem. I believe the T in the GUI indicates that the track was read fine, however the markers on the track indicate it isn't the physical track that was expected to be read. So ...

Re: Help with damaged floppy disk

I believe the seams on many (but not all) 5.25 disks were ultrasonic welds, but the sleeves? They varied, thin paper, thick card or that plastic-feeling paper which I can't remember what it is called now.

Re: Help with damaged floppy disk

I beg to differ on the glue/vapour/residue issue. Some will release a vapour that either stains or clouds surrounding areas, but as pointed out, this means the incorrect glue was probably used. Personally I don't think I would use "superglue" on a floppy. I have often wondered what the commonly used...

Re: Floppy drive selector board

@SomeGuy You are too kind for suggesting I was only "over thinking it a bit". I was aware that the original Shugart interface supported four drives but it was my understanding that the Kryoflux only supported the IBM PC interface (hence the two-drive jumper on the board). In some ways I can understa...

Floppy drive selector board

This isn't really a feature request but I have this crazy idea of an add-on board (actually, more like a controller board) for Kryoflux but have neither the time, resources or knowledge to implement it. I suspect it may be quite costly as well, but I'm documenting it here for anyone to pursue should...

Re: What type of drives: HD or DD for reading/writing DD disks

I'll answer the parts I'm confotable answering. I'm also answering in a general sense so I preface this by saying that there will of course be exceptions and difficulties in real life. The KF is intended to be used with standard PC floppy drives that use the standard 34 pin interface. For the purpos...

Re: The Copyprotection Wars

Some of your pain points also remind me of the pains of a certain modern console.

Re: Write a Mac 400/800K sector image using Kryoflux

So just thinking this through in regards to reading Mac disks, I wonder (under the right circumstances) if it may be possible for a poorly reading drive to give better results by intentionally increasing the RPM of the drive. That is assuming that the Kryoflux can do sufficient sampling to capture t...

Re: Bad floppies :(

Sideways! Although my drive maintenance skills really only go as far as head cleaning, I would suspect either a slightly loose head (causing it to be out of alignment unless gravity assists) or perhaps the (ribbon) cable from the head to the PCB may be slightly loose/out (or the equivalent from some...

Re: Bad floppies :(

So that was after you gave everything a clean?

In regards to the Apple // formats, you should also search these forums for AGC (automatic gain control), as specifying this setting can make a significant difference to your dumping efforts.
