Some time ago, July 1985, Paul Campbell posted a hack to upgrade
a 512K to 1Meg. He called it Monster Mac and it work on 128K machines
that had been hacked, using the Dr. Dobbs method, to 512k.

Given that the MacSnap upgrade is not straight forward for such
machines I have decided to try Mr. Campbells method. It requires
piggy-backing the memory chips and adding a a second decoder chip.
Fortunately my wife is experenced at such things and she believes
that it will work.

We are seeking comments from anyone who has done this upgrade.
Any suggestions and/or experences would be helpful.

When my upgrade is commpleted I will repost the orginal hack with 
our own comments.

Thanks,
Paul Fink
