You need to make sure your PC can read single-density (FM) format,
because cylinder 0 head 0 is in that format.

I wrote a Linux program to dump images of Xerox 6085 diskettes. It's
pretty crude, but I could send it to you if it's of use.

I've been working on a better Linux program to dump diskette images
in .dmk format. So far I've only tested that program with 8-inch
disks, but it should handle 5.25 and 3.5 as well. When it's a bit
further along it will appear on SourceForge as part of the dmklib
project.
