DIGITAL COMPUTER NEWSLETTER. VOLUME 18, NUMBER 3
A 1966 Defense Technical Information Center newsletter on digital computers, issued for naval research and engineering readers in the United States. Its two pictures are plain line diagrams of electronic circuitry: a grid of selection and reading circuits with numbered rows and columns, and a block diagram of driver, detector, and flip-flop units wired around transistors. A designer could borrow their clean schematic linework, grid structure, and labelled block layouts for technical infographics.
