MacWrite 4.5 will not run on any Mac with a 68020 or 68030 as the 68000's 
trap command is not compatible with these chips.  Because of this
incompatiblity programs written in MacForth won't run either.

To solve this problem you need to run MacWrite 4.6 or later.  Version 5.0
is really the minimum however as 4.6 is quite buggy.  The best solution 
is to upgrade to MacWrite II.  I was able to do this a year and a half ago
for $25 through our University computer store.  I would think anybody should
be able to contact Claris and upgrade quite cheaply.
