    The motivation behind the creation of the Cambridge University Mathematical Laboratory and its original terms of reference are described. The changes to the laboratory caused by World War II are discussed. The Cambridge Mathematical Laboratory was reestablished in 1945 under the directorship of M.V. Wilkes. The ways in which Wilkes developed the work of the laboratory and built up a research team ... View full abstract»

    The discovery of a paper-tape relic consisting of an undebugged program written for the EDSAC computer in 1949 is described. It is believed that this program is the first real, nontrivial application ever written for a stored-program computer. An examination of the program sheds new light on the extent to which the debugging problem was unanticipated by early computer programmers, and the motivati... View full abstract»

    Early applications of EDSAC, including the calculation of prime numbers, solutions of algebraic equations, and experimental learning programs, are described to illustrate the wide field of programs written in the first years of stored-program computing. The influence of the library routines, such as those of the solution of differential equations, on progress in applied mathematics is considered. ... View full abstract»

    The highlights and background of the EDSAC programming system as it developed from 1948 in anticipation of the EDSAC completion to the improvements made for the second Cambridge computer are presented. The initial orders and subroutines, methods for running a program, and ways to find program faults for EDSAC are described. The design of EDSAC 2 and programming of EDSAC 2 are discussed.<> View full abstract»

    The background to the Lyons Electronic Office (LEO) project is reviewed and the ways in which it came about that a large-scale food and catering business, J. Lyons and Company, set out to build its own computer and later went into the business of building and supplying computers to others are explained. Some of the leading people involved are introduced. It is described how their interest in compu... View full abstract»

    The principal hardware features of EDSAC 2, which was developed in the Cambridge University Mathematical Laboratory, are described. EDSAC 2, which came into operation early in 1958, was the first computer to have a microprogrammed control unit and established the viability of microprogramming as a basis for computer design. At the mechanical level of organization, EDSAC 2 was packaged in a bit-sli... View full abstract»

    The research developments at the Cambridge University Mathematical Laboratory after the completion of the EDSAC 2 project and up to M.V. Wilkes' retirement from his chair in 1980 are outlined. In particular, the Titan system, which supported high-performance multiprogrammed computing, the CAP capability-based computer, and the Cambridge Ring, a digital communication ring, projects are described.<<...
