In such a way you can raise up two of the boards in back (on the quad extenders) with the one in front installed normally but with the half-height extender upside-down and plugged into the top connectors, so the edge fingers of the extender plug into the top blocks. Yes, it's ugly, and it only gains you access to half of the board you're trying to poke at. Building some sort of ribbon cables to substitute in for the top blocks/upside-down extender would be more, uh, flexible, but I was fortunate that what I needed to look at was on the unobscured side. - Josh

A couple of those per cable and you are all set. You may want to contact him about acquiring the female edge connectors, as they can only be ordered in bulk. (It might be my turn to order them, if he's out.) Vince
