You are misunderstanding some of the terms. There are basically three types
of Ethernet connector:
-- Thick, also called DIX or AUI: this uses RG-213 coax, about 0.4 inch
diameter, and each workstation is tapped onto this big cable with a drop that
terminates in a 15-pin D connector.
-- Thin, also called cheapernet: this uses RG-58 coax, about 0.2 inch
diameter, and each workstation is tapped in with a T connector using BNC.
-- UTP, also called 10Base-T: this uses twisted pair wiring that looks
something like telephone wiring, in a star topology with 8-pin RJ-45.
Thick is pretty much obsolete. Your NE-2000 card apparently has a BNC
connector for Thin and an AUI connector for Thick. The dorm apparently has
an RJ-45 connector for UTP, not Thick. While you could buy a transciever for
about $35 which would adapt the card to the jack, it would be cheaper and
easier to replace the card entirely. Interfacing an AUI connector to an
RJ-45 connector is not just a matter of cabling.
What you want is a nice NE-2000 clone which has both Thin and UTP connectors,
what is commonly known as an Ethernet "combo" card. You don't care about
Thick at all. I have seen such cards for as little as $20, and you can get
really nice ones for about $30.

You might be happier with Connect, especially since the installation is a lot
easier and faster for the NetWare client. Also, very few colleges would run
Novell, but I suppose it's possible. By far, most colleges would run TCP/IP,
in which case you would definitely want Connect.
