Kip,

You have a very simple method for determining if the problem is with your Coco 
or with the software being run. Use an emulator and repeat EXACTLY the steps 
that cause your hardware to crash. If the emulator does not crash, that suggests 
a hardware problem if the settings on the emulator are correct. If the emulator 
crashes, that suggests there is a problem with software.

Why don't you post exactly what you do step by step to cause the crash? Include 
the size of OS9Boot, the amount of free memory (mfree), the number of screens 
(shells) active, etc.?
