ICL Technical Journal available on the web

The ICL Technical Journal was a significant series with articles about computer and system developments in ICL and beyond. It was published between 1978 and 2000, with 43 issues in 14 volumes.

A collaboration between Fujitsu and the National Museum of Computing has now enabled the original journals to be published online.

Many ICL engineers, designers, developers, and technical managers wrote articles on their work and innovations. The articles demonstrate the enormous contribution made by ICL people to the development of modern computing, in many cases forming the basis of practices still in use today.

A selection can be viewed on the Fujitsu website .

32 issues are now available online, with more to follow.

The contents for each issue are shown and each issue can be searched using the Adobe search tool, and you can search across the set.

There are some articles on computer history topics, and CCS members may find the following of interest. On ICL research and development there are three articles by Prof. Martin Campbell-Kelly (in Volume 5 Issue 1 for 1904-1959, Volume 6 Issue 1 for 1959-1968, and Volume 6 Issue 4 for the New Range. These articles were subsequently published in Martin’s book on the history of ICL).

And on the origins of the 2900 series mainframes there is an article from 1978 by John Buckle (in Volume 1 Issue 1).

Ada Lovelace 200th anniversary celebrations at Oxford University

In 2015 the University of Oxford will celebrate the 200th anniversary of the birth of computer visionary Ada Lovelace. The centrepiece of the celebrations will be a display at the University of Oxford’s Bodleian Library (13 October - 18 December 2015) and a Symposium (9 and 10 December 2015), presenting Lovelace’s life and work, and contemporary thinking on computing and artificial intelligence.

Ada, Countess of Lovelace (1815-1852), is best known for a remarkable article about Charles Babbage’s unbuilt computer, the Analytical Engine. This presented the first documented computer program, to calculate the Bernoulli numbers, and explained the ideas underlying Babbage’s machine and every one of the billions of computers and computer programs in use today. Going beyond Babbage’s ideas of computers as manipulating numbers, Lovelace also wrote about their creative possibilities and limits: her contribution was highlighted in one of Alan Turing’s most famous papers Can a machine think?. Lovelace had wide scientific and intellectual interests and studied with scientist Mary Somerville, and with Augustus De Morgan, a leading mathematician and pioneer in logic and algebra.

The display, in the Bodleian’s new Weston Library, will offer a chance to see Lovelace’s correspondence with Babbage, De Morgan, Somerville and others, and her childhood exercises and mathematical notes. The Symposium, on 9th and 10th December 2015, is aimed at a broad audience interested in the history and culture of mathematics and computer science, presenting current scholarship on Lovelace’s life and work, and linking her ideas to contemporary thinking about computing, artificial intelligence and the brain. Confirmed speakers so far include Lovelace’s direct descendent the Earl of Lytton, Lovelace biographer Betty Toole, computer historian Doron Swade, historian Richard Holmes, computer scientist Moshe Vardi and graphic novelist Sydney Padua. Other activities will include a workshop for early career researchers, a “Music and Machines” event, and a dinner in Balliol College on 9th December, the eve of Lovelace’s 200th birthday.

Oxford’s celebration is led by the Bodleian Libraries and the University of Oxford’s Department of Computer Science, working with colleagues in the Mathematics Institute, Oxford e-Research Centre, Balliol College, Somerville College, the Department of English and TORCH. Oxford has a remarkable history of programming research, with two winners of the ACM A M Turing Award, the Nobel Prize for Computer Science, and the unique breadth and depth of Oxford’s expertise brings a variety of perspectives to understanding Lovelace and the remarkable intellectual community around her, whose ideas underpin modern computing.


Founded in 1989, the Computer Conservation Society is a joint venture between the British Computer Society, the Science Museum and the Museum of Science and Industry in Manchester.

Our primary mission is to preserve historic computers, develop awareness of the history of computing, and encourage research. We run many specialised projects, organise public lecture series, and publish a regular bulletin.

Membership of the society is open to all.
