The Honeywell (formerly GE) mainframes also have this ability, much like
the IBM machines cited above (335@ihlpl).  It does come in handy for
debugging the kernel, but since the address is absolute, it's not much use
to time-sharing users.

I'm still looking for a machine that will trap references to uninitialized
data.
