The Rise and Fall of Plug-Compatible Mainframes // AHC, vol. 27, № 1, January-March 2005. P. 4-16. The rise and fall of plug-compatible mainframes spanned more than 20 years. RCA, whose 1964 Spectra 70 System was compatible with the IBM System/360, chose another path altogether, so Amdahl in 1970 became the first true PCM manufacturer. Other companies--notably Fujitsu and Hitachi--soon followed, seeking to complete with IBM in the mainframe arena. This article traces the history of PCMs, which includes an intriguing incident of industrial espionage.
No Classical or historical bibliography had an entry until now for a book examining the Ancient Greek Numerical Systems. Epigraphical hand-books and introductory works, when referring to this subject, listed the hard-to-find articles published by Marcus Niebuhr Tod from 1911 to 1954.
An account is presented of the early years of a pioneering computer company, Engineering Research Associates, Inc. (ERA), which was formed in 1946 at St. Paul, Minnesota, with Navy encouragement. This company was merged into Remington Rand Inc., in 1952, as was Eckert-Mauchly Computer Corporation two years earlier. These mergers created the basis for what later became the Univac division of Sperry Rand Corporation, or Sperry Univac. ERA's technological contributions are discussed, along with the company's pre-merger growth and financing problems. There were post-merger problems, primarily of organizational integration, but solid groundwork was being laid for Sperry Rand's eventual success in the data processing industry.
The introduction of the UNIVAC computer is among those subjects in the history of computing that has received wide attention. The issues and sequence of events leading to the development of the UNIVAC have been covered in such writings as Nancy Stern's From ENIAC to UNIVAC and Herman Lukoff's From Dits to Bits, and was the subject of the 1981 AFIPS Pioneer Day. However, less attention has been devoted to the place of the UNIVAC from approximately 1952 to 1956, after its initial development. A two-day oral history conference was convened in May 1990 to examine the role and effect of the UNIVAC on computing and the computer industry in the mid-1950s.
This is by far the most important monograph on Andean systems of information registry since the Ashers' volumes in the late 1970s. Urton provides a platform for a whole new generation of studies." - Frank Salomon, Professor of Anthropology, University of Wisconsin-Madison. In an age when computers process immense amounts of information by the manipulation of sequences of 1s and 0s, it remains a frustrating mystery how prehistoric Inka recordkeepers encoded a tremendous variety and quantity of data using only knotted and dyed strings. Yet the comparison between computers and khipu may hold an important clue to deciphering the Inka records. In this book, Gary Urton sets forth a pathbreaking theory that the manipulation of fibers in the construction of khipu created physical features that constitute binary-coded sequences which store units of information in a system of binary recordkeeping that was used throughout the Inka empire. Urton begins his theory with the making of khipu, showing how at each step of the process binary, either/or choices were made. He then investigates the symbolic components of the binary coding system, the amount of information that could have been encoded, procedures that may have been used for reading the khipu, the nature of the khipu signs, and, finally, the nature of the khipu recording system itself--emphasizing relations of markedness and semantic coupling. This research constitutes a major step forward in building a unified theory of the khipu system of information storage and communication based on the sum total of construction features making up these extraordinary objects.
The paper discusses the method used by Zhao Youqin (1271–?) in his treatise Ge xiang xin shuto confirm Zu Chongzhi's (429–500) approximate value 355/113 of . Zhao Youqin inscribed a square into a circle and performed an iterative procedure of calculation of one side of a 2n-sided inscribed polygon for n= 3, … , 14. Included is a biographical sketch of Zhao Youqin, who was an astronomer, mathematician, and physicist as well as a Taoist monk and alchemist. A translation of Zhao's description of his method is given in the Appendix.
