CPU280 3.5" 1760K format support

Post by sijnstra »

Hi,

I'm trying to import an image from a Kryoflux sampled CP/M (ZCP3) 3.5" high density 1760K floppy using Tilmann Reh's specs. These specs are:

Code: Select all

   Nr. Name                 Siz Trk SecGr Sec Dense SMod Hd0 Hd1 Psk Iv Ms TT  Skw Bls   Dir Off
   =============================================================================================
   45  REH 3.5" HD           3"  80  1024  11    HD  Sec   0   1   1  -  -  -    2   4   256   0
When I try to drag the kryoflux .raw file into either the beta or the release versions of the HxCFloppyEmulator, I get "Load error! Read file error!"
When I try to load the kryoflux .img file (using skew = 2, interleave =2), it converts the file to .hfe, and the "track analyzer" view of the data looks reasonably legitimate - i.e. I can see the first sector with the format block, and the directory sectors look reasonable, however, I get a read error on my CPU280. It won't read the mounted .hfe file.

If I convert other 1440K CP/M .img files, they work as-is perfectly well, so I know the CPU280 is happy to read images from the HxC2001.

Is there something about the format that might not be supported? I'm hoping to use a few of this format due to the more convenient larger size, and that I have a few disks in this format.

Thanks!
Shawn

Can you share these images/dump ?

Yes I can. I've shared a zip file with both the .raw and the .img at:

Change the .raw extension to .ctr, then just drag & drop it on the main window (the caps library should in the hxc software folder).

Thank you for following up.

I tried renaming the .raw to .ctr and get the same error. If I turn on debug, I get the following message in the log:

ERROR : No loader support the file D:\cpm\UZIX280.ctr !

I've also tried using the latest v2.2.2.1 on sourceforge.

I am not sure what you mean by caps library. Am I missing something?

Thanks,
Shawn

Hi Jeff,

Thank you for those links! The drag an drop now successfully converts the file from the raw format to .hfe which I can save to the sd card.

I'm not sure how to debug the next problem which is reading the emulated floppu. If I have a mounted floppy image of a 1440K floppy it works perfectly. For the 1760K for some reason it seems to not work. It seems to be unable to read even the first sector.

I've tried updating the firmware of the hxc2001 to the current beta v1.8.6.20a.upd

Any thoughts?

Share the non working converted image.
