Roland posts a MacOS 9 driver for their UM-1 MIDI Interface here . The download is posted as a .tgz file and not a Stuffit archive.
Stuffit (the default version in the MacOS9Lives image) expands the file, but the driver installers (the "Driver E" files) just show up as non-executable documents. Can anyone help me get past this? Presumably there are three potential solutions:
--1-- Suggest a better location to download UM-1 MIDI drivers for MacOS9 -- perhaps as a Mac-friendly Stuffit archive.
--2-- Suggest a better way to extract the .tgz file within MacOS 9, so that the original executable status is preserved.
--3-- Suggest a way to make the non-executable documents actually execute (assuming the files aren't corrupted in some other way).
Thanks in advance,
