+Apple Universal Interfaces
+--------------------------
+
+The Universal Interfaces used to be a free download from Apple. However,
+they have taken the site offline and the license agreement prohibits
+redistribution, so this might be a bit hard to find nowadays.
+
+You do need a version that still supports 68K Mac development, so
+version 3.4 will NOT work. Basically, look for something no later than 1999
+or so.
+
+The package might be somewhere in this huge snapshot of Apple's FTP site made
+by the Internet Archive:

+
+If you have a Mac or some other way to read DiskCopy images, grab the MPW 3.5
+image from:
+
+http://macintoshgarden.org/apps/macintosh-programmer%E2%80%99s-workshop
+
+and use the CIncludes directory from there.
+
+Put the C header files into a directory called "Universal Headers" at the top
+level of the Retro68 directory.
