dart is a generic disk copying utility for the Macintosh that can read
and copy Roland sampler disks.

samdisk is a utility for PCs that can read and index (and manipulate?)
Roland sampler disks.

disk-tools.shar is Gary J. Murakami's .h and .c files for reading
and manipulating sample disks - extra cool.

smac.hqx is Terje Finstad's <t.g.finstad@fys.uio.no> Roland disk utility
for Macintoshes.  I'm not sure if he wants it publically available (yet),
so you might not be able to actually read the file.
