The M68HC11EVBU2 is an extended promotional version of the original M68HC11EVBU that adds 32K RAM. The board runs in normal-expanded mode by default to allow use of this extra RAM. The MC68HC11E9 processor includes the BUFFALO monitor in ROM although the special bootstrap mode can also be used for development as used by PCbug11. If the extra RAM is removed then this board can be configured to look like the original M68HC11EVBU.
