BAD TRAP
-----------------
Cause: A bad trap can indicate faulty hardware or a mismatch between
hardware and its configuration information. Data loss is possible if the
problem occurs other than at boot time.

Action If you recently installed new hardware, verify that the software was
correctly configured. Check the kernel traceback displayed on the console to
see which device generated the trap. If the configuration files are correct,
you will probably have to replace the device.

In some cases, the bad trap message indicates a bad or down-rev CPU.

Technical Notes: A hardware processor trap occurred, and the kernel trap
handler was unable to restore system state. This is a fatal error that
usually precedes a panic, after which the system performs a sync, dump, and
reboot. The following conditions can cause a bad trap: a system text or data
access fault, a system data alignment error, or certain kinds of user
software traps.

I'd pull the memory boards and anything else you have stuffed in it and see
if it will boot.  R&R the SIMMs on the main board if it fails.  After that,
I'd imagine it is time to find another set of SIMMs or hit the dumpster.  

Mixing SIMM speeds (100, 80, 70, 60ns, etc) might cause problems.  I think
these beasts need 100ns or better.  Faster is better, but mixed is like
asking for dropped batons in a relay race.  

One last thought.  My experience is that 90+% of all electronic device
failures are mechanical in nature...

Okay, colour me confused...
