Paul,
I'm not an 11 expert but don't most instruction fetches
(or the last clock phase on an instruction) cause the pc
to increment by one?
PDP-11 instructions are 16-bit. Since memory is
byte-addressed, the instruction counter should normally
increment by 2, except where immediate operands are used.
