I *so* wish I had thick coaxial Ethernet, but alas, my present : physical facility is just too small for that: my present coax Ethernet : network is contained within a single machine room which is a converted : bedroom. 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.
