Re: Help troubleshooting a non-working new board

If the board is connected type "lsusb" on a comand line. There should be an entry "Atmel Corp. at91sam SAMBA bootloader" in the list...

If that's not the case, it looks as if the board is bad!

Need Help with really obscure floppies!

I got two floppies from a friends collection today (one IBM and the other for MAC) and guess what, I can't read anything but noise from it! Any help is much appreciated! http://davidkrause.de/Floppy-Calculator1.jpg http://davidkrause.de/Floppy-Calculator2.jpg http://davidkrause.de/Floppy-Calculator3...

Re: I have a KryoFlux ... now what?

The 2040 is 48 tpi and should be readable with a 96 tpi drive in doublestep mode. But they had a different sector layout to the later cbm drives! Tracks 18-24 had 19 sectors instead of 18 on later drives! I don't know if that is covered by the dtc decoder!? Thou vice can help to get the files off su...

Re: Imaging 100TPI 77 track Exidy Sorcerer disks on a Micropolis 100TPI

You're right with the dumb drives, but didn't they use the index pulse to check if the drive is spinning or stucking? If the pulses don't come at the estimated times, they stop the motor as far as I remember (to avoid destroing the inserted floppy). That's why I thought testing with a hardsectored f...

Re: Imaging 100TPI 77 track Exidy Sorcerer disks on a Micropolis 100TPI

Are you really shure that your drive (which is a hard-sectored one) did once write the floppies (soft sectored as you said) that you are trying to read now? These old drives might behave weird if a floppy is inserted that has no sector holes... Is it possible to calibrate with a hard sectored floppy...

Re: I have a KryoFlux ... now what?

Oops, bad news again! The cbm 8050 is a 100tpi drive. Usually 5.25" drives are 96tpi. So you need a 100tpi drive which are very rare today!

Re: Allways: Control command rejected by the device

It would be fine to know which OS you are using...

Maybe one of the hints in this thread may help:

Re: Cable does not match Pin1 on floppy drive

No you didn't missunderstand anything. The cable is correct but the drive has the notch on the wrong side! I've never seen anything like that bevor! Acording to the manual at http://www.radioradar.net/en/files.html?fid=608767 the connector should be fitted in the opposite direction like on any other...

Re: I have a KryoFlux ... now what?

1. It's probably all MFM sector image. There are many tools out there who could help you to get the files of the image. A really good one is this https://hxc2001.com/download/floppy_drive_emulator/HxCFloppyEmulator_soft.zip ! 2. The 8280 was an 8" drive! If your floppies are 5.25" I would try with t...
