Yeah, it will work.  The pinouts of the two 6811's are exactly
compatible (the Forth chip is 52 pins, right?).  The one problem I
foresee is some weirdness with the serial line (the Mini Board
hardware echoes every character it receives).  You might have to write
your own terminal program to discard these extra characters, because I
think the Forth chip performs its own software-echo of incoming
characters (to display them on your terminal screen).
