List of Figures
ENIAC as installed at the University of Pennsylvania, in a US Army photograph used by theNew York Timesin its 1946 report. This image defined public ideas of what an electronic computer looked like. The machine was configured by setting switches and wiring connections between its many panels, which collectively established a room within a room in which its operators and associated punched card machinery worked. Corporal Irwin Goldstein, an Army maintenance technician, is in the foreground setting data on a portable function table later used to hold encoded program instructions. Technician Homer Spence and two operators, Frances Bilas and Betty Jean Jennings (later Jean Bartik), work in the background.
The logical architecture of EDVAC as described in theFirst Draft. Reproduced from Thomas Haigh, Mark Priestley, and Crispin Rope,ENIAC in Action(Cambridge, MA: MIT Press, 2016, p. 145).

Computer installations on college campuses often created images composed of text characters to show off the capabilities of the IBM Chain Printer. Such pictures were later shared online. This widely shared example of what was later called ASCII art was reportedly created by David Wright in 1978.16

The drive had a capacity of five million characters and required two additional cabinets holding power supplies and controller electronics to function.

An IBM System 360 installation, c. 1965. Well into the third generation, mainframe computers still relied heavily on magnetic tape for mass storage. Note the raised floor, punched card reader, the typewriter-like console printer, and next to it, an IBM 3270 video terminal and the distinctive slope of the main console. At the lower left is a suite of fixed disk drives; at the lower right, a set of chain printers housed in soundproofed cabinets.

System/360 was designed for technical computing as well as business data processing. In both markets, IBMs fast and rugged chain printers were a crucial selling point.

Consultant W. Robert Widener promoted the concept of management decision rooms based around computerized screens with armrest controls in his 1968 article New Management Concepts.
By the mid-1960s, Univac promoted its computers as total management information systems with almost magical powers to centralize and simplify the control of large diversified corporations.Fortune, October 1965, pages 3233. Courtesy Unisys.
