How to read CPM 5.25 floppy disks?

Hi all,

Anyone have any ideas how to read (and obviously back up) my CPM 5.25
diskettes left over from my Kaypro 2x CPM machine used 1984-1987?
Somewhere I have a normal IBM PC compatible 5.25 drive, but CPM
floppies had different formatting, I think both in software and in the
iron oxide.

I'm thinking if I can ddrescue these things to a file, and loop-mount
them using some sort of CPM format (didn't the mount command used to be
able to do that?), maybe I could get the info into a file
representation instead of a drive representation.

Thanks,

SteveT
