Specifically, the global at 0x02D6 was changed from "BasicGlobs" (documented
only through rumour and not in IM) to "ExtendedMem" in the Mac II.  Megamax
uses this global to place a copy of A4 for various reasons (as in A4 was
used as a pointer to the C global variables and string variables).  Thus,
when any program compiled with the Megamax compiler ran on the Mac II, the
Mac II died in initialization.

I patched my copy of version 3.0a to work with the Mac II.  If anyone's
interested, I'll send them instructions to patch their compiler.  I don't
guarentee the patch; it's only a temporary holdover until I get an updated
version from Megamax.

For those who can't wait...
