There are no protoyping areas on the EVB.  (Unless they've changed the
design since I got mine.)  Note that the EVB is intended to simulate 
an HC11 with replaceable ROM, to help one design HC11-using devices.
It thus is not really designed to be used in a non-prototype system.

Functionally, the HC11 is always in single-chip operating mode, so
hardware not part of the EVB cannot be in the memory map.  This means 
you are forever limited to the two 8K blocks of RAM (though you could
replace the 8K ROM with one of your own).

A furthur point is that the EVB monitor takes up 182 bytes of the 
zero-page RAM.
