Actually, the way you troubleshoot a caged boardset like the G80 is with a
card extender. You plug it into the cage, and it extends the edge connector
to the front of the cage. You can then plug the card you're working on into
the extender and have full access to the front and back of the card.

There may be someone on the list who is willing to sell or lend you their
extender. IIRC Mark sold them all, but who knows. If he's around, he might
chime in.

There are other less favorable options, but they'll most likely cause more
harm than good, unless you're very careful.

Thanks,

P.S. Who on the list is going to be at CAX next weekend? I'll be there...
