Hard Cover. Zustand: Very Good. First Edition. First Edition. Volume XXVII ( 27 ) of the Annals of the Computation Laboratory of Harvard University. Based on Aiken's course of lectures "Organization of Large-Scale Digital Calculating Machinery" taught during the spring term of the 1947-48 academic year at Harvard. Lacks the dj. Previous owners bookplate on front pastedown (John W. Sponsler). Remains of old tape for "home-made" dj in the past on front and rear pastedowns. Otherwise clean, sound binding. Hard Cover.

Hard Cover. Zustand: Very Good. Zustand des Schutzumschlags: Fair. Second Printing. Second Printing. Volume XXVII ( 27 ) of the Annals of the Computation Laboratory of Harvard University. Based on Aiken's course of lectures "Organization of Large-Scale Digital Calculating Machinery" taught during the spring term of the 1947-48 academic year at Harvard. The present copy was owned by Peter F. Strong, who was not only a staff member of the Computation Laboratory but is recognized as a collaborating writer with Aiken on Progress Reports #8, 13, and 16 of the Progress Reports of the Computation Laboratory. (see Norman and Hook Origins of Cyberspace and the Preface by Aiken). A nice association (Strong's name and address pencilled in 1971 on front pastedown). A very good copy with wear to corners and head/tail spine panel. Dj chipped at edges (with large chip missing in middle of spine panel), not price clipped. Previous owners name also stamped on front endpaper (Lewis C. Clapp, computer pioneer and consultant). Authors: The Staff of the Computation Laboratory [ Harvard University ] Howard Aiken ( Preface ). Hard Cover.

"The electromechanical Harvard Mark I was the first programmable calculating machine to actually produce mathematical tables, fulfilling the dream of Charles Babbage originally set out in print in 1822." (OOC, #411) "The manual for the Harvard Mark II, a relay-based calculator built for the navy during the last year of World War II. It was installed at the Naval Proving Ground in Dahlgren, Virginia, in 1948, where it was used mainly for the development of ballistics tables. The Mark II's design did not depart radically from that of its predecessor in that it employed electromechanical equipment and was programmed via paper tapes, 'but otherwise it was very different. Where the Mark I used rotary mechanical systems (with magnetic clutches) for storing numbers, the Mark II used relays. The way of programming it was very different (i.e. the instruction set was different). The fact that it was essentially two machines which could be combined for large jobs or have each half running independent jobs was quite different.' (MRW Other innovations included a floating decimal point and a new type of relay. It was considerably faster than the Mark I . The Manual for the Harvard Mark II calculator was written primarily by Grace Hopper, assisted by Constance K. Rawson, Peter O. Cioffi and Richard D. Woltman. It was completed by Charles H. Richards and K. B. Mitchell" (OOC) Volume XXIV of the Annals of the Computation Laboratory of Harvard University. All volumes in the series were heavily used, and finding copies in dust jacket is getting difficult. Literature: Hook and Norman, Origins of Cyberspace, #416, 411 (referring to Mark I).
