I ran into one such, the driver disk for a speech recognizer.  It
didn't seem to have any self-sync nybbles.  It was slow as heck
running its modified DOS (which I presumed, but didn't prove, tried
every possibility until sectors started reading).  Since it used a
normal DOS filesystem, I was able to copy it file by file to a regular
disk, using a cassette tape for an intermediary.
