7700 is all Octalink, 3 different BBs for track, road and triple. The DA ones use needles as well as balls if I remember right.
The crank arms were a very pretty evolution on the previous generation, and Dura-Ace was the first to be hollow (again, iirc - I think the arms were forged in a C section and the back welded on at first before they figured out how to do them in one piece).
The major bummer about 7700 cranks is that they weren't anodised! What suckage. Stupid clearcoat instead. Although I suspect the 25th anniversary special edition ones were proper.
