4.2 died on our VAX.

[Alex White]

Our 780 all had on the console floppy which came from dec a file called
	CRASH
which is for crashing vms -- it prints several registers, then stuffs
negative one into the pc, kernel at ipl 31 into the psl, and continues.
This immediately causes a trap, which unless things are screwed up in
the various disks should cause your dump.
To use, on the console
