M.S. Mahoney – Articles on the History of Computing is a page of links by the Princeton historian to articles about the history of computing. He argues in “The History of Computing in the History of Technology” that “the history of computing has yet to establish a significant presence in the history of science” (p. 1 of the PDF). As a result a lot of the popular history of computing out there is “heroic” and focuses on people or companies and insider knowledge.
One interesting quote from Wallace’s “Thinking About Machinery” (Wallace 1978, pp.237ff.) draws attention to the importance of tinkering to inventors like Edison and the problem of looking only at verbal materials.
He makes a very interesting point about the tripartite nature of computing. That it is a engineered machine (so there is a history of the engineering), it is a logical machine (so there is a history of the logic and mathematics) and it is programmed to do things (so there is a history of the craft of programming and media development.)
