I can't let this go by without a comment.  The above scheme will ATTEMPT to
run a Macintosh binary from A/UX.  Most mac binaries won't run under A/UX.
There is an A/UX manual called something like "The A/UX Toolbox Guide" that
goes into great detail about what applications can do that will keep them
from working under A/UX.  In summary, the most common problem is a lack
of 32-bit cleanliness.  Most mac applications know that they are running
in a 24-bit address space and feel free to didle with high bits of addresses.
This won't work under A/UX, which uses the PMMU to provide a 32-bit address
space.  Future versions of the mac OS are also likely to use 32-bit addresses.
Anyway, we hope that developers will start cleaning up the applications
enough to make them A/UX friendly.  But in the meantime, don't be surprised
when your favorite mac applications don't run under A/UX.

ps.  The above directions for running mac binaries are only good for A/UX
versions up to Beta 1.0.  After that, you need to use a program called rcnvt
to produce the new "AppleSingle" or "AppleDouble" format resource files.
Type: "man rcnvt" to get more information on this.
