in the mid-90s i was invited to fix several schools' networks, a couple were novell and i forget what the others were (edit: also appletalk, which was similar but used 2 pairs on "telephone jacks", including little phone jack resistors), and those BNC connectors (or were they TNC?) were connected to stiff wires so any movement of the very heavy PCs connected to them tended to shear solder joints. I even had to replace "thinnet" coax that rats had eaten through. I bet if i open my parts cabinet i still have enough stuff to build a token ring 10base2 network right now.
