Thought this might be of use to someone with a network card without 10BT... Looks like you could use this as an AUI trasnceiver as well. It powers on and shows link, but I have not tested it any further. It did not come with a power supply, but my 12v dlink one works fine with it. I would like to sell it without the power supply, but if you really really want one - I can dig through my box-o-supplies and find one.
How about $15 +ship?
Open to offers and trades as well.
