I really wonder how the CDC link worked. The channels were electrically strange, and certainly not easily amenable to communicating with anything other than CDC controllers or perhaps a serial line through one of the front ends.
I did hear of a proposal at NADC around 1977 to try to hook into telnet and ftp from a CDC using some hack of the serial stuff. The idea didn’t impress me: it would have taken a lot of hacking to get a kludge working. It always took a lot to make CDC hardware play well with others.
