I am using mpsim for DOS.  The documentation says that it
works for both the 16Cxx and 17Cxx processor families.  Is there a
strategy one can use to take code that will actually run on a 12C5x
chip and at least be able to test it for fatal errors like
subroutines that don't return and logic errors?  In other words am I
just going to have to wing it on 12C5x's or can I write the code for a
close relative of that group in the 16Cxx family in order to make sure
that it should run?

        Also, is the 17C43 too recent to simulate with mpsim?
