OK then I guess it *was* taking the place of a BC11. :-) I just meant it wasn't jumping directly from one DD11 to another, so the "source" end really was three Bergs, not a DD11 slot. I've seen that done only with the fancy flexprint cable, not two paddles and three ribbon cables, so I was kind of assuming that there's some impedance-matching (etc.) problem with using ribbon cables for more than one hop. But then again ... I chose the digital version of EE as my major precisely because I knew I'd flunk Fields and Waves. Transmission lines are black magic as far as I'm concerned! John Wilson D Bit
