Richard,

As I am somewhat of a newbie to it myself, my advise is limited, but I
will warn you of this.  The reset vectors are in two different
locations.  The 54 is at x1FF, and the 84 is at x000.  Also, the 84 has
and interrupt vector at x004.  Other than that they should be pretty
much plug and pray compatible.
