Issue 1: Don't use inits you don't understand
Issue 2: Don't use MMInit
Issue 3: Don't use MMInit under System 7

The Memory manager Init was designed to fix a performance problem with
allocating high numbers of chunks of memory on certain machines under
6.0.x.  It conflicts with System 7, the version you have probably
conflicts with System 6 (we don't know which, uh, "helpful person"
distributed this to the net, but they sent a version out that was
severely damaged) and the performance problem is fixed correctly in
System 7 all by itself without any INITs (Extensions.)  Throw away that
damn INIT and reboot.
