Trap type 0 is bus error. The two causes of this are either addressing memory location
that does not respond (as opposed to being umapped) or an word operation on an odd
address.
Since you have a cpuerr print out you have a 44/45/70 CPU. The 020 value indicates that
it was the bus timeout case.
Something touched memory that was mapped in but didn't physically exist.
