Re: Kryoflux stopped working - no red led

I wonder what caused that then, for I imagine it would have had to be something considerable (like 12v shorting to 5v). I suggest caution. Glad you found the problem anyway.

Re: Kryoflux stopped working - no red led

Okay so you probably haven't done something obviously wrong then - I was leaning towards short on the board (dropped screw, ESD, board resting on drive casing, etc). Incidentally I read comments elsewhere that poly-fuses can become high-resistance for extended periods of time (weeks/months) under so...

Re: Kryoflux stopped working - no red led

Yes I understand that (and it should be working with only the Kyoflux plugged in). My question still stands though... how were you powering the drive when the incident occurred? Another possibility is that somehow there was a short circuit on the Kryoflux itself, which would/should only be due to a ...

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

Sorry for another post, but incidentally someone has just released ProDOS v2.4 for the Apple // series.

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

I remember that there was a System Extension you could add on legacy Macs to enable support for the ProDOS filesystem. So a machine with that extension and PC Exchange would be able to read and write Mac HFS, Windows FAT and Apple // ProDOS. I don't remember anything about the capacities (never had ...

Re: Kryoflux stopped working - no red led

Maybe you were powering the drive from the Kryoflux? That would be my guess - it sounds power related.

Re: Kryoflux board inside a PC?

I'm not sure of this but I think you need to be aware of a couple of things here. You can't presume the precise ordering that devices will be powered up. It is going to depend on factors relating to the design of the power supply and motherboard (and whatever the connected devices are). You are also...

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...
