You can also use the "CRASH" command script that comes on the Berkeley
11/780 boot floppy (I seem to remember it being part of the build script
for the floppy, anyway; I know it's on our floppy); it's only "bug" is
that the comments it prints out say something about crashing a VMS system,
but UNIX dies just as nicely as VMS when you jam a nasty value into the PC...

Just type a ^P and type "@CRASH" when you get the prompt.

Don't know whether any such script exists for 730s or 750s, or whether
the Berkeley cassettes include them.
