Yes I know, but that doesn't help.
I want MacOS running on top of Mach, not Mach running on top of MacOS, for
the very simple reason that when MacOS on the former crashes, the whole
machine has to be rebooted. On the latter, you kill the MacOS process(es) and
start over.
When you're trying to use the machine with multiple tasks (say, program
development, major UUCP node, and reading NetNews while the compiler is
busy -- incidentally that's exactly what my fx is doing right now), you start
to realize the difference pretty fast.

Fine, but that doesn't answer my question either.

To repeat: What happened to the CMU Mach port and why can't people like me
get it? It is available for machines with 80386 CPUs...
