Forgot to add: this thin coax Ethernet interconnects several MicroVAXen
(including ivan.Harhan.ORG, the machine on which my mail lives and from
which I am sending this post) running 4.3BSD-Quasijarus, and a Cisco
2500 router which connects my retrocomputing centre to
ARPANET^H^H^H^H^H^H^HSDSL. The SDSL connection is made via a device of
my very own design and make that connects to the copper pair, handles
the physics of 2-wire full-duplex transmission, and converts SDSL/ATM to
V.35, or more precisely EIA-530, which then goes to the Cisco 2500.
