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.
