- 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).
