     I'm *really* getting tired of this discussion.  I have answer Mr.
Kenyon privately via 'mail' but this posting shows that it is likely he
has not been receiving my mail.  As such, I hope the Atari fans will
bear with me and we'll all hope he reads this:

     OS-9 does the same or similar 'fancy footwork' without an MMU

>what about multiple processes

     OS-9 handles multiple processes without an MMU

     No.  If OS-9 can do it, then you can do it with some
other Unix or Unix clone.  Then again, why bother, you'll have
OS-9 anyway. :-)

     I can live without the protection.  I *have* been living without
it on my Color Computer, running OS-9 (6809) for some time now.  I
think most Atari 520ST users will find it quite satisfactory.  Please
go look at OS-9 68K before you do any further posting.  I read
net.micro.atari to read about Atari.

    Your right, UNIX DOES need an MMU.  I'll call Microsoft and H-P immediately
    and tell them to stop selling Xenix and HPUX because they can't possibly 
    work.  Boy are they going to be pissed.  Oh well, they should have asked
    if they needed an MMU before they went ahead and ported UNIX to hardware
    that doesn't contain an MMU.
