Solution: Probing the ROMs responsible for the above (D10, 11, 12) didn't show anything untoward was going on so I then turned my attention to the next part of the chain which was an LS273. All seemed to be working aside from an output which was stuck high. The input looked healthy so I pulled it and replaced it to repair the board.
