Ethernet is not, never has been, and never will be a ring (loop). IEE 802.3 "A physical layer standard specifying a LAN with the CSMA/CD access method on a BUS topology. Ethernet LANs follow the 802.3 standard" BUS topology is not a ring. It is a two wire (single wire with shield) configuration terminated at each end with 50ohm resistors. The minimum network is simply a tee with two terminators. Of course all of the above refers to thin net not 10BASE-T (twisted-pair) in which the NeXT is connected to a twisted-pair hub such as Cabletron's 10Base-T TPMIM-T Module using 4 wires (one pair twisted together for transmitting and one pair twisted together for receiving). jim standard disclaimer on my opinions.
