It is additional work and logic, but it can be done.  In some cases, it may
make sense, in other cases, it may not ("Whaddya mean you put that 32 megabyte
memory board into your 2000!").  

In any case, Zorro III boards are required to act intelligently in a Zorro II
backplane.  If they can't act as a Zorro II board, they much magically disappear
so as to allow any additional Zorro II boards to be correctly configured.
