These tune files were readable until February, 2018,
but then they became illegible due to reversion to the no-newline format
used by old Mackintosh system. The files are still there,
and can be downloaded, but most ABC software can't handle them.
So I copied them here, converted the CR chars to LF chars.
If someone notices that the problem has been fixed,
perhaps during migration to a more modern system,
could you send me a mesage
I can rescan them, and delete these copies.
