As Paul and der Mouse suggested, I agree that it would
be worth making
up a short flexible AUI cable. Cat 5 is 100-ohm, and ribbon cable is
not far off that IIRC; you could use STP instead of UTP to get the
shield (some Sun cables are STP), or just ignore it for really a short
(a few inches) cable. Or a chunk of old good-quality serial cable
I wonder if IDC cable would work for a very short (a few inches) length?
Just enough to turn the transceiver 'round the corner' or whatever.
