I think there are adaptors/convertors for bnc, so i think you should be able to use it with a modern 10mbit tp cable.
I have/had one myself somewhere, but never was able to test if those convertors really work.
The cheapest, most available way to do this in the US is with a simple hub. Just find any old 10baseT hub with a 10base2 (BNC thinnet) port. I used "ARK" "SOHO" brand for my home network, however,
this monster is presently the cheapest thing Froogle turns up. (That one will require a little more hacking in setup, because the presence of the serial port suggests it's a managed hub, and you might have to haul out a null-modem cable and un-configure it out of whatever the previous user had it doing.)
I doubt you'll beat five bucks on a "media converter" alone, and this way you get extra ports for whatever else you don't mind hanging off unswitched(?) 10baseT.
Note that installing your own BNCs is 'interesting,' but can be done -- having an appropriate crimper or a huge honking pliers with the right kind of channel in the teeth helps a lot. (I forget the details.)
And remember that each end of the coax has to terminate in a T with a terminator on it, while even in a simple configuration, going "straight through" without them will never work. (In this day and age, it's probably cheaper to get tees and terminators by buying generic Realtek NE2000 clones than going to Radio Shack -- or at least you get a free ISA network card with each -- check your local hole-in-the-wall, you never know what brand will include them in the package.)
Edit: Obviously, once you have the 10baseT/10base2 hub in place, you just "uplink" it to your 10/100 switched or existing LAN if you've got. There are limitations on how many segments/repeaters or whatnot you're 'allowed' to have with ethernet, but you won't hit them in that configuration alone (this is pretty basic stuff).
