Fatal error 911 is the ADB controller getting confused.  It's
frequently caused by overheating.  If you don't have a cooling
fan, you might want to try one and see if the problem goes away.
If you already have a fan, then it may be the the ADB controller
is actually getting confused, but I've never heard of this
happening at only 9MHz.

The 4 cache RAM chips are all identical (with the possible
exception of speed rating).  It doesn't matter what order
they are installed, but it DOES matter that the notch on the
chips is pointing up.  The DIP switches also need to be
changed if you decrease ram size.  Note:  the cache RAM
chips are very static-sensitive!  If precautions aren't
taken, the chips can be fried quite easily.
