Harvard Ibm Automatic Sequence-Controlled Calculator
The basic scientific description of this machine as of September 1, 1945, is contained in:
Aiken, Howard H., and Staff of the Computation Laboratory, A Manual of Operation for the Automatic Sequence-Controlled Calculator, Cambridge, Mass.: Harvard University Press, 1946, 561 pp.
The machine has changed rather a good deal since Sept. 1, 1945. Some circuits have been removed. Other circuits have been added. The capacity of the machine to do problems has been greatly increased. The Computation Laboratory at Harvard University is cordial towards scientific inquiries, and some unpublished, mimeographed information is available at the laboratory regarding the details of these changes.
