I almost got MacLanding to run on a Mac II. I think the remaining
problem was the screen size and some hard-wired system constants. The
first problem was that it used self-modifying code to make system trap
calls. This doesn't work when the instruction cache is enabled. To
disable the cache, use a public domain cdev or write your own program
(an FKEY would be adequate) to do it. With the cache disabled, it might
work, since it works on a regular SE.

Good luck,
