The 7104 (and it's 1GHz plugins) used a re-designed connector that was good to a GHz. It was mechanically compatible with all the others, but quite different electrically. See pages 4 and 5 of this:

No.  The follower board on the 7000 series edge connector is good to 1GHz+.  The 7104 works in exactly that way. 


On the 7A21N the two pins on the 4-way connector at the top are used for DC, and carry the trace position control from the front panel of the 7A21N

No, they were intended for exactly what they are used for in the 7A21N.  The 50 ohm connection through the edge fingers of the circuit board is good, but not great and has reflections that would not allow a really high frequency connection.
