Subject: Cambridge ring interface

In the Electron, BBC and Master memory map the area between &FC30 and 
&FC3F is reserved for the Cambridge Ring Interface. What was this 
interface used for? From the sound of it I'd guess it's some sort of LAN 
interface for a network used at Cambridge university.
Has anyone ever seen one of these, and is there any documentation still 
available?

Cheers,
Eelco
