Re: Oh dear, did I fry my KryoFlux?

No, something must have gone wrong. We have used dozens of these drives. This is more curiousity than anything, does that include the models without the diodes? If the driver IC gets hot, it's likely it's burned. No part of the device should get hot, it was designed in a way it does not need coolin...

Floppy disk/drive curiousities

I am particularly curious about floppy disks and floppy drives and would really love it if I had some direction on what to search, where to read up on much of this, rather than just specific answers alone to my questions. Does the SPS actually retain documentation like this anywhere and would it be ...

Re: Oh dear, did I fry my KryoFlux?

Good news! The NEC FD1231M arrived today. Probed the relevant pins and it seemed to be all within acceptable ranges.

I was able to succesfully get the KryoFlux to interface and read data off floppy disks! Hopefully writing will work too.

Thank you again David for all the help you've provided.

Re: Oh dear, did I fry my Kyroflux?

Just to be clear, are you saying this model of drive without the diodes installed can actually potentially damage a kryoflux (and perhaps other controllers)? Perhaps not a direct answer to your question, but on the page on which pictures reside on Google translate says: The four wired 1N118 diodes,...

Re: Oh dear, did I fry my KryoFlux?

Okay, I have never had a Sunday delivery happen before, weird times we live in... But I got the multimeter. I tested the power adapter and that seems to be within acceptable ranges? 5v-line.jpg 12v-line.jpg I went through and testing along the Molex adapter cable too, just because I could, the drive...

Oh wow! I stand corrected. This is really helpful. ♥️

Re: Oh dear, did I fry my KryoFlux?

Where do you live I am located in Northern Ireland. It would not be a big deal to mail the board to somewhere in Europe (although the mail system is a bit slow at the moment). if the board has been damaged and it would be viable to try getting it repaired instead of buying a new board? Open to tryi...

Re: Oh dear, did I fry my KryoFlux?

You should measure the pins with the negative probe connected to GND. That's the black wires on the molex or the metal shielding of the drive. Ah, I understand! To be save, you can measure also the output voltage of your supply. It should be 12V on the yellow wire and 5V on the red one (negative pr...

Re: Oh dear, did I fry my KryoFlux?

That looks as if you are feeding voltage from the drive into the kryoflux board! So, the earlier connection I made to the KryoFlux board with the Molex connection should not have done anything? I would disconnect the drive from the board, power up the drive alone and look for the pins 8, 26, 28, 30...

Oh dear, did I fry my KryoFlux?

I was overly excited to have obtained a KryoFlux yesterday and set forward to setting it up. I am can accept blame and understand if I need to buy a new KryoFlux if this is my fault (even though it makes me sad that the delivery of a new board will probably take a while again). However, my biggest c...
