        We are seeing quite a bit of requests for high speed differential
pair boards; edge-2-edge, broadside, you name it. Recently I received one
where the two complements were none of the above, but rather were joined at
a central point. They are not close enough to be edge to edge, nor do they
even run in the same general vicinity; rather they run to a central point.
        Any idea what this is and how to measure, specify to make sure that
the diff impedance is what is required (zod=100 ohms, z=50).
