MaM seems to make hard-coded assumptions about the values of some 
low memory globals. I got it to mor-or-less run on a II by examining
memory with the micro-debugger and replacing the globals. Instead of
rebooting when done, however, I got a spectacular crash where my screen
went crazy ALL THE WAY TO ITS EDGE. Not the normal screen boundary, but
the whole physical tube... out to the plastic!

Upon rebooting, however, MaM came back with it's "All Tests Passed"
message.

Conclusion: Wait for the author to issue a machine-independent version.
