Those unimplemented trap errors are probably your unix partition running 
out of disk space.  If you're trying to install the compiler, make sure 
you install that *first* and delete the man pages to save lots of space.  
Then, don't install misc11 or man11.  Even then, a 40 Meg partition is 
pushing it.  You should probably consider putting part of the software on 
small partition on your internal drive.

Okay.  There's no similarity there.  MMU stands for Memory Management 
Unit, and all computers have one of some sort.  Powerbooks all use 
PMMU's, or Paged Memory Mgmt. Units.  It's just a chip that handles the 
storage and retrieval of data to & from your memory chips.  I don't 
remember my PowerBook model numbers, but I think that system is greyscale 
at least.  Did you remember to set the bit depth to black-and-white in 
the monitors control panel?  Is virtual memory turned off (memory control 
panel)?  Is 32 bit addressing turned on (also memory cp)?

That was replaced with a more obvious "This has not been tested on your 
system and will probably crash" message.
