Boston University had a terminal network that ran over CATV wiring.
I'm not sure I ever knew what protocols were being used for "native"
services. We also wired up the UB boxes via parallel port to VAXen and
ran TCP/IP between VAXen (4.2BSD and VMS).

An even earlier generation of "terminal network" was the Gandalf switch.
