Interface Message Processors for the ARPA Computer Network
This is a 1975 technical report by Bolt Beranek and Newman, prepared for the ARPA computer network and distributed through the Defense Technical Information Center, describing interface message processors and their message handling. The pictures are plain line diagrams: boxed memory layouts with labelled blocks and pointer arrows, a store-and-forward buffer diagram, and a network logical map of host computers linked by lines, which a designer could use as a schematic or network-diagram reference.
