Re: Connecting two 3,5" Drives causes strange errors

There is the (pair of) jumpers on the Kryoflux that needs to be set correctly for two drives. I don't know if it would cause these problems if set incorrectly, but it is worth looking at. Check the Kryoflux documentation for this. There may just be something up with one of the drives. I can generall...

Re: Incorrect track errors with attempted flippy mod

My guess is that -DDx is just coincidental (how many times have you verified that adding the extra parameter results in track+1 instead of track-1?) It sounds more likely that the alignment is changing with each attempt you make (perhaps changing when it reaches either end of its extents). But then ...

Re: First attempts at reading Apple II flippy

Sorry to post again, just a second part to be aware of. You mentioned that your Apple reads some disks fine but the Kryoflux doesn't get anything at all. Do yourself a favour and search these forums for "AGC", which can have an affect on how well your drive can read the types of floppies you are wor...

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.
