The Graphics Terminal Display System: A Powerful General-Purpose CAI Package
This 1975 technical report from the Defense Technical Information Center, written for naval training research, describes a computer-aided instruction system built around a graphics terminal. The single picture is a block diagram showing a central SDSU 360/50 computer linked through a Nova 1220 and leased modem lines to remote sites, each with a Tektronix 4014 graphics terminal, a random-access slide projector, and a Votrax speech synthesizer. For a designer it offers a plain, schematic flowchart style with boxes, labelled connectors, and a clear top-down hierarchy that could inform simple system diagrams.
