(AIKEN, H.H.) “Survey of the Mark IV Harvard Computer”, abstract. In: “Some Comments on the Conference of the Association for Computing Machinery in Pittsburgh, May 2nd & 3rd”. This is a short summary of a paper read by Aiken at the national ACM meeting in 1952 in a set of carbon copies of a 6-page abstract/report, 1952. No sign of an author or any further bibliographic information. Printed on onion skin paper. Good condition, or better. $100
Also included: Warren McCulloch “An Upper Bound on the Information Capacity of a Synapse” (1 paragraph, mentioning 12x10^10 neurons but not an estimate of synapses [10x10^13] or synapse size, though this is only 1952); D.L. Johnson, “Standardized Printed Circuit Units for Digital Computers” (1 full page) and “Digital Storage Using Ferromagnetic Materials” (half-page). The core interest here to me are the Aiken and McCulloch summaries. Interesting piece of computing ephemera. I haven't been able to find evidence that these abstracts were published—the papers were, but not this material.
“It is the purpose of the Association for Computing Machinery to advance the science of numerical computation, in particular the design, development, construction and application of modern computing machinery for performing operations in mathematics, logic, statistics and kindred fields, and to promote a free interchange of information about such machinery in the best scientific tradition.... For the first time the attempt is made here to make such information available to a wider public in a more permanent form, by assembling [a] volume the transcripts of papers presented at the meeting...”
