Much has been argued in this group about whether or not Intel has a better
MMU and how slow Motorola was in getting their MMU out.

Custom MMU's are not particularly hard to build, and many companies have
done so.  Pinnacle Systems/Logic Process Co/Whoever they are next week uses
a custom MMU built out of 45ns or 35ns (depending on which machine) static
rams.  The Pinnacle XL/MPulse 10 (sounds like a merger of 2 bank cards here
in Dallas, MPact and Pulse :-) runs a 68K at 12MHz, 0 wait states, and
according to the latest rumors the Pinnacle XL020/MPulse 20 runs a 68020
at 16MHz, 1 wait state.  Supposedly John Bremsteller has been working on
getting the 020 up to 25MHz with only 1 or 2 wait states.

So, with a lack of 'on chip MMU' this little company has done about as
good as you can get.  I see no reason to argue about whether the MMU
belongs on chip or off, so long as you don't take a performance hit for
it.

And yes, when someone said an IBM-PC/?? would beat my 6MHz 68000, I too
laughed.  I have never seen a 286 running more than 4 or 5 users at 8MHz,
but I have seen 8 or 9 users on a 68000 at 6MHz, and it just gets better
with more memory, faster clock speeds, faster disks, and all of the other
new goodies that have come out in the 5 years I've had my machine.
