I'm posting this for a friend.  He has posed a very interesting question
and my own machine with a 68K is down because of power problems and I
can't try it out.

Does anyone here *KNOW* what the 68K will do when confronted with the
following instruction?

          move.w (A4)+,(A4)+

It seems that this could do any of a number of things, depending on the
actual microcode for the move instruction.  Please, no speculations.
There is enough of that sort of thing on the net :-)
