The new UFCD isn't referenced in those early manuals. The line drawings in those documents don't fully illustrate the details of the design. I think the confusion stems from the fact that the illustrated display is drawn as a single, square screen, rather than a row of six linear LCDs as seen fitted to actual, older aircraft. The UFCD controls are the same however, whereas the newer system features slightly different knobs and the buttons are now rectangular rather than square.
