THE ALOHA SYSTEM - ANOTHER ALTERNATIVE FOR COMPUTER COMMUNICATIONS
A 1970 technical report from the Defense Technical Information Center, written by Norman Abramson of the University of Hawaii, describing the ALOHA radio system for linking remote terminals to a central computer. The single picture is a block diagram, rotated sideways on the page, showing consoles linked by radio transmitter and receiver units and modems to a central IBM computer. A designer could take its plain flowchart conventions: boxes labelled in capitals, paired arrows for two-way links, and wireless symbols at the top.
