Original IBM film (1974) announcing IBM's “Systems Network Architecture” (or SNA), a collection of formats and protocols for interconnecting computers and their resources for optimal communication.
Lots of computer hardware is shown. SNA is described very clearly in this film, including an animated block diagram. One could describe this as “SNA 101” which is a great place to get started.
Actual title is "Link to the Future."
