No, I dont have the TOS book... But I did know that the helm officer was covered.
However this is a TNG conn officer, to match all those pilots in Command Red that we have seen at the helm of various starships. I see the position as a slightly altered role, combining both pilot and navigation, with even engineering and command elements... A good multi-role for the up and coming officer on the fast track.
The plus side is that the conn officer was completely my own work. How close was I?
