One system popular in Germany at the time used a modified German phone =
plug ("TAE"), and the resulting system was marketed as "EAD" or Ethernet =
Anschluss Dose.  The coax was way too heavy and stiff for the small =
plug, and would regularly unseat the connector.  Since the phone plug =
was never designed to have a defined impedance, any run longer than =
about 50 meters for the segment was hit and miss.
