There are no known problems with 7.5 and MCL; however, there were also
none with 7.1.2, so it is likely that some extension or init you are running
is the real culprit.  What were some of the symptoms of the "horrendous
bugs"?

If you are trying to run it on the PowerPC, you need to 1) turn off the modern
memory manager and 2) either run without virtual memory or get the MMU5
resource from ftp.cambridge.apple.com and add it to your image (with resedit
or some similar tool).
