That is a 10 Base 2 connector.  It's an ethernet card, 802.3 frames, but
which transmits on a RG59 coaxial RF cable.  The cable has to be terminated
at each end with a 50 ohm terminating resistor for the electrical proper-
ties to be correct.  The computers are connected to the network cable in 
series.

The "10Base2" moniker indicates that the cable can be up to 200 meters
in length without being out of spec, I think.
