Somewhat of a cross port question.. I just plugged an adfs disk from an
Acorn RiscPC into a 1.6R/i386 computer:

# mount -t filecore /dev/wd1d /mnt
# ls /mnt
                     !Music F      f      ionsF  n      nsF
# ls -lR /mnt | more
ls: : No such file or directory
ls: : No such file or directory
ls: : No such file or directory
ls: F: No such file or directory
ls: f: No such file or directory
ls: ionsF: No such file or directory

Anyone interested?
