UNIVAC I Computer System
Saved from the Internet on 3/9/2010 Created by Allan Reiter UNIVAC I Computer System After you look at this yellow page go to the blue page to find out how UNIVAC I really worked. My name is Allan Reiter and in 1954 began my career with a company in St Paul, Minnesota called Engineering Research Associates (ERA) that was part of the Remington Rand Corporation. I was hired with 3 friends, Paul S. Lawson, Vernon Sandoz, and Robert Kress. We were buddies who met in the USAF where we were trained and worked on airborne radar on B-50 airplanes. In a way this was the start of our computer career because the radar was controlled by an analog computer known as the Q- 24. After discharge from the USAF Paul from Indiana and Vernon from Texas drove up to Minnesota to visit me. They said they were looking for jobs. We picked up a newspaper and noticed an ad that sounded interesting and decided to check it out. The ad said they wanted people with military experience in electronics. All three of us were hired at 1902 West Minnehaha in St. Paul. We then looked up Robert Kress (from Iowa) and he was hired a few days later. The four of us then left for Philadelphia with three cars and one wife. Robert took his wife Brenda along. This was where the UNIVAC I was being built. Parts of the production facilities were on an upper floor of a Pep Boys building. Another building on Allegheny Avenue had a hydraulic elevator operated with water pressure. -

Memorial Tributes: Volume 10 J.PRESPER ECKERT 71 J.PRESPER ECKERT 1919–1995 BY LEO L.BERANEK JOHN PRESPER ECKERT, or as he preferred, J. “Pres” Eckert, was born April 9, 1919, in Philadelphia, Pennsylvania. He received the bachelor of science degree from the University of Pennsylvania in 1941. His 1943 master of science degree in electrical engineering was from the University’s Moore School of Electrical Engineering. Pres and his wife, Judith, had four children and made their home in Gladwyne, Pennsylvania. He was known as a serious worker who wanted things done right. His family and his students at the university attest to his readiness to be helpful and his devotion to vigorous and healthy living. He died June 3, 1995, in Bryn Mawr at the age of seventy-six. A brilliant student, Pres was named a part-time laboratory instructor in his second graduate year at the Moore School. His charge was to teach the principles of engineering to students from other fields with the goal of making them able to work effectively in the World War II effort. His class comprised more than thirty students, sixteen of whom had their Ph.D.s. It was through that course that he met John W.Mauchly, whose doctorate was in physics. In 1942 and 1943, Eckert became involved in improving a version of Vannevar Bush’s differential analyzer, invented at the Massachusetts Institute of Technology. After considerable success, Mauchly and he discussed how much further its performance could be improved by more precisely machined parts and Copyright National Academy of Sciences. -
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. -

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. -
Doing Mathematics on the ENIAC. Von Neumann's and Lehmer's
Doing Mathematics on the ENIAC. Von Neumann's and Lehmer's different visions.∗ Liesbeth De Mol Center for Logic and Philosophy of Science University of Ghent, Blandijnberg 2, 9000 Gent, Belgium [email protected] Abstract In this paper we will study the impact of the computer on math- ematics and its practice from a historical point of view. We will look at what kind of mathematical problems were implemented on early electronic computing machines and how these implementations were perceived. By doing so, we want to stress that the computer was in fact, from its very beginning, conceived as a mathematical instru- ment per se, thus situating the contemporary usage of the computer in mathematics in its proper historical background. We will focus on the work by two computer pioneers: Derrick H. Lehmer and John von Neumann. They were both involved with the ENIAC and had strong opinions about how these new machines might influence (theoretical and applied) mathematics. 1 Introduction The impact of the computer on society can hardly be underestimated: it affects almost every aspect of our lives. This influence is not restricted to ev- eryday activities like booking a hotel or corresponding with friends. Science has been changed dramatically by the computer { both in its form and in ∗The author is currently a postdoctoral research fellow of the Fund for Scientific Re- search { Flanders (FWO) and a fellow of the Kunsthochschule f¨urMedien, K¨oln. 1 its content. Also mathematics did not escape this influence of the computer. In fact, the first computer applications were mathematical in nature, i.e., the first electronic general-purpose computing machines were used to solve or study certain mathematical (applied as well as theoretical) problems.
