Mike,

Here is a quote from Alan DeKok who developed most of Level III.
"Level III enables you to have about 25 _different_ processes
running in different windows, all at the same time!  The only way that this
is possible on a Level II system is to strip your OS9Boot file down to almost
nothing.  Level III allows you to keep all of your favorite modules in your
OS9Boot."

In short, memory is handled differently from Level II and appears to be used 
more efficiently. Unfortunately, the source code for Level III seems to have 
been lost and the actual workings can't be compared with the current versions of 
Level II. As NitrOS-9 is more efficient than OS-9 (on which Level III is based), 
comparisons of Level III with current code need to be done.
We don't know which is better or what the difference would now be.
