Make sure you have the correct one. Early Master version didn't have
the contention hardware on it. This was done in software by comparing
the bytes sent with the bytes read back. Very soon though, the boards
has the same contention hardware on it, as the BBC-B has.

(input notCTS of 68B54 is used for that)

Johan
