DUBBELDOS: Backing up 13 sector disks


by Paul Schlyter

You could run my little utility "DubbelDOS": run it on an
unmodified version of Apple DOS 3.3: it will remove the FORMAT
command, and then patch DOS 3.3 so it recognizes both 13-sector
and 16-sector disks, switching automatically as needed.  With
DubbelDOS installed, you can use FID to copy files to/from 13/16
disks in any combination (13==>13, 13==>16, 16==>13, 16==>16).
With DubbelDOS you'll lose the ability to format floppies though.
