I was looking at this page on DigiBarn, https://www.digibarn.com/collections/parts/ethernet-taps/index.html and the old Ethernet transceivers. For the life of me I cannot remember what the transceivers used with the Xerox 6085 (Daybreak) looked like in 1989. There was wall to wall Xerox 8000 servers mixed in with 6085-Is at the software testing lab, in El Segundo, California, DSBU (Documenter Systems Business Unit) but that is now mostly a faded memory.
