There is only one version of Microware Pascal.  It works on Level One or Two
(There is another version for the 68K of course).  The Microware distribution
of the C compiler includes two versions.  The level one version sacrifices
speed for size.  It has one more pass than the level two version.  However,
if you want, you can run the level one version on a level two system.  I had to
do that for some forgotten reason when I first got my C compiler.

As a rule all programs that run under level one will run under level two and
vice versa.  The exceptions to this rule are programs that use the additional
SVCs available under level two, and level one programs that reference addresses
than won't be in their address space under level two.  

... One other exception: some programs need the full 64k - delta address  space
available under level two.  The level two C compiler is an example.
