Joel,

There use to be a way to add floppy access profiles for new formats.  I had
to googling it a long time ago to be able to dd the coco floppies that
way.  Might need to create a special profile for the OS-9/68K disks as
well.  So you might want to try googling it.

I will try to google it when I get home tonight my time and see if I can
find it then.
