Not true...  Just like MacBSD, A/UX has to be ported to new macs.
Basically, the problem is that Apple keeps building new machines
instead of improving old machines.  The SE/30, II, IIcx, and IIx
are all basically the same machine.  For instance, Apple has stated
that A/UX will never run on the AV machines.

The reason that you haven't seen many programs that don't run on
just a few macs is that most programs are "well-behaved" in that
they run in the MacOS and use the Mac system for most services
(like memory access, disk I/O, sound, etc).  We don't.  We blow
the MacOS away and take over the machine.  For a variety of
reasons...
