Listing of 60s mainframes/minis with CRT displays?

The original PLATO terminal interconnect was a custom design intended to distribute 1260 baud synchronous data to 1008 terminals out of a single terminal mux interface, for transmission over a single link (essentially a video stream, compatible with microwave video distribution transmitters). (See Bitsavers, pdf/univOfIllinoisUrbana/plato, reports X-26 and X-27.) In the mid 1970s a host to host network was constructed specifically for PLATO systems, at first just between University of Illinois and CDC. That was the ?Doelz network? (after its designer). I have not been able to find any documentation on what the hardware looked like; what little I have been able to deduce about the software is pretty gnarly. It certainly did not bear any resemblance I can see to any other network, nor (fortunately) did any other network pick up any Doelz ideas. At some point, PLATO systems started using CDCnet I/O; for example, the FAA system that was the last running production PLATO system worked that way. That provided terminal connections via Telnet, and PLATO host to host file transfer via some protocol I don?t remember. paul
