DIGITAL COMPUTER NEWSLETTER. VOLUME 17, NUMBER 2
A 1965 newsletter from the Defense Technical Information Center, issued for naval research and digital computing readers, with a block diagram of a computer system. The single picture is a schematic of the GE-235 central processor linked to a Datanet-30 communications controller, tapes, printer, magnetic disc, card reader and card punch, with Model 35 teletypes along the right edge. A designer could take from it the plain, boxed-and-arrowed diagram style of mid-century technical drawing, with thin rules, rounded and rectangular nodes, and dashed connecting lines.
