content: As a graduate student in electrical engineering at the University of California at Berkeley, Thomas E. Osborne began thinking about the design of a desktop electronic calculator suited for calculating the very large and very small numbers encountered in scientific work. In January of 1964, he formed the firm Logic Design, Inc., to develop his ideas. By late 1964, he had built this prototype keyboard and display, as well as a prototype logic unit. For these materials, and related documentation, see accession 1978.0311. Some years after the donation of the prototype "green machine", Osborne donated these sheets documenting the purchases of Logic Design, Inc., between 1964 and 1966.
