Perhaps yoy problem is now considered im ossible because of prohibitive costs asso- ciated with co b methods of solution.- The UNIVAC* SYSTEM has been developed by the Eckert-Mauchly Computer to solve such problems. Within its scope come %fm%s as diverse as air trarfic control, census tabu- lakions, market research studies, insurance records, aerody- namic desisn, oil prospecting, searching chemical literature and economic planning. The UNIVAC COMPUTER and its auxiliary equipment are pictured on the cover and schematically pre- sented on the opposite page.

Sperry Rand's Third-Generation Computers 1964–1980
Sperry Rand’s Third-Generation Computers 1964–1980 George T. Gray and Ronald Q. Smith The change from transistors to integrated circuits in the mid-1960s marked the beginning of third-generation computers. A late entrant (1962) in the general-purpose, transistor computer market, Sperry Rand Corporation moved quickly to produce computers using ICs. The Univac 1108’s success (1965) reversed the company’s declining fortunes in the large-scale arena, while the 9000 series upheld its market share in smaller computers. Sperry Rand failed to develop a successful minicomputer and, faced with IBM’s dominant market position by the end of the 1970s, struggled to maintain its position in the computer industry. A latecomer to the general-purpose, transistor would be suitable for all types of processing. computer market, Sperry Rand first shipped its With its top management having accepted the large-scale Univac 1107 and Univac III comput- recommendation, IBM began work on the ers to customers in the second half of 1962, System/360, so named because of the intention more than two years later than such key com- to cover the full range of computing tasks. petitors as IBM and Control Data.

UNIX Operating System Porting Experiences*
UNIX Operating System Porting Experiences* D. E. BODENSTAB, T. F. HOUGHTON, K. A. KELLEMAN, G. RONKIN, and E. P. SCHAN ABSTRACT One of the reasons for the dramatic growth in popularity of the UNIX(TM) operating sys- tem is the portability of both the operating system and its associated user-level programs. This paper highlights the portability of the UNIX operating system, presents some gen- eral porting considerations, and shows how some of the ideas were used in actual UNIX operating system porting efforts. Discussions of the efforts associated with porting the UNIX operating system to an Intel(TM) 8086-based system, two UNIVAC(TM) 1100 Series processors, and the AT&T 3B20S and 3B5 minicomputers are presented. I. INTRODUCTION One of the reasons for the dramatic growth in popularity of the UNIX [1, 2] operating system is the high degree of portability exhibited by the operating system and its associated user-level programs. Although developed in 1969 on a Digital Equipment Corporation PDP7(TM), the UNIX operating system has since been ported to a number of processors varying in size from 16-bit microprocessors to 32-bit main- frames. This high degree of portability has made the UNIX operating system a candidate to meet the diverse computing needs of the office and computing center environments. This paper highlights some of the porting issues associated with porting the UNIX operating system to a variety of processors. The bulk of the paper discusses issues associated with porting the UNIX operat- ing system kernel. User-level porting issues are not discussed in detail. -

Fundamentals of Computers (Information Technology)
NME 1 : FUNDAMENTALS OF COMPUTERS (INFORMATION TECHNOLOGY) UNIT-1 Introduction and Data Representation in Digital Computer - Historical Background of computer - merits and limitation of computer - First to fifth Generation of Computers - Characteristics of Computers - Classification of Computers Introduction and Data Representation in Digital Computers Data and instructions cannot be entered and processed directly into computers using human language. Any type of data be it numbers, letters, special symbols, sound or pictures must first be converted into machine-readable form i.e. binary form. Due to this reason, it is important to understand how a computer together with its peripheral devices handles data in its electronic circuits, on magnetic media and in optical devices. Electronic components, such as microprocessor, are made up of millions of electronic circuits. The availability of high voltage(on) in these circuits is interpreted as ‘1’ while a low voltage (off) is interpreted as ‘0’.This concept can be compared to switching on and off an electric circuit. When the switch is closed the high voltage in the circuit causes the bulb to light (‘1’ state).on the other hand when the switch is open, the bulb goes off (‘0’ state). This forms a basis for describing data representation in digital computers using the binary number system.

Creativity – Success – Obscurity
Author Gerry Pickering CREATIVITY – SUCCESS – OBSCURITY UNIVAC, WHAT HAPPENED? A fellow retiree posed the question of what happened. How did the company that invented the computer snatch defeat from the jaws of victory? The question piqued my interest, thus I tried to draw on my 32 years of experiences in the company and the myriad of information available on the Internet to answer the question for myself and hopefully others that may still be interested 60+ years after the invention and delivery of the first computers. Computers plural, as there were more than one computer and more than one organization from which UNIVAC descended. J. Presper Eckert and John Mauchly, located in Philadelphia PA are credited with inventing the first general purpose computer under a contract with the U.S. Army. But our heritage also traces back to a second group of people in St. Paul MN who developed several computers about the same time under contract with the U.S. Navy. This is the story of how these two companies started separately, merged to become one company, how that merged company named UNIVAC (Universal Automatic Computers) grew to become a main rival of IBM (International Business Machines), then how UNIVAC was swallowed by another company to end up in near obscurity compared to IBM and a changing industry. Admittedly it is a biased story, as I observed the industry from my perspective as an employee of UNIVAC. It is also biased in that I personally observed only a fraction of the events as they unfolded within UNIVAC. This story concludes with a detailed account of my work assignments within UNIVAC. -

John William Mauchly Born August 30, 1907, Cincinnati, Ohio; died January 8, 1980, Abington, Pa.; the New York Times obituary (Smolowe 1980) described Mauchly as a “co-inventor of the first electronic computer” but his accomplishments went far beyond that simple description.

Potts Medal, Franklin Institute, 1949; John Scott Award, 1961; Modern Pioneer Award, NAM, 1965; AMPS Harry Goode Memorial Award for Excellence, 1968; IEEE Emanual R. Piore Award, 1978; IEEE Computer Society Pioneer Award, 1980; member, Information Processing Hall of Fame, Infornart, Dallas, Texas, 1985. Mauchly was born in Cincinnati, Ohio, on August 30, 1907. He attended Johns Hopkins University initially as an engineering student but later transferred into physics. He received his PhD degree in physics in 1932 and the following year became a professor of physics at Ursinus College in Collegeville, Pennsylvania. At Ursinus he was well known for his excellent and dynamic teaching, and for his research in meteorology. Because his meteorological work required extensive calculations, he began to experiment with alternatives to mechanical tabulating equipment in an effort to reduce the time required to solve meteorological equations. -
