The chapter recounts the author's experience working at the Los Alamos computation center during the Manhattan Project, where early IBM bookkeeping machines were used to solve complex differential equations essential for atomic bomb design. It highlights the limitations of these mechanical and semi-manual computing processes and presents John von Neumann's visionary proposals for fully electronic computers, binary number systems, internal memory, stored programs, and universal computing machines that would revolutionize computational efficiency and autonomy.
The chapter details the Johnniac computer, a unique IAS-type machine built by Rand Corporation in 1954, inspired by John von Neumann's architecture principles. It highlights the historical context of von Neumann's work on stored program computing, the proliferation of IAS machines worldwide, and the Johnniac's specific features such as its use of a time-sharing operating system and memory upgrades. The Johnniac remains significant as the only complete surviving IAS-type machine besides the original.
