MacKermit works on a Mac II; however, the Sumacc C compiler runtime
library does not.  Unfortunately, the current version of MacKermit is
built with the Sumacc C compiler.  The problem is the traps and calls
to various in-rom/ram packages on the Macintosh are built in-line, on
the stack as I remember, by the Sumacc C compiler runtime libraries.
This doesn't work too well on a 68020 based system like the Mac II
because the 68020 has an instruction cache.

If you are willing to live with a (moderate) performance degradation,
simply turn off the instruction cache with following MPW asm program:
		Machine MC68020
	nocache main
		clr.l d0
		movec d0,cacr
		rts
		ENDP
		end

Simply "restart" to turn the cache back on.
