Sample text

There were no photocopiers in those days, so Wilkes stayed up late into the night reading the EDVAC Report. He recognised it at once as ‘the real thing’ and decided that the laboratory had to have an EDVACtype stored-program computer. A few weeks later he received a telegram from the dean of the Moore School. They were organising a summer school in computer design, and would he like to attend? Wilkes would, and did. Unfortunately, because of shipping delays he was only able to attend the latter part of the course, but that was all he needed – he now had a detailed insight into the EDVAC design.

The truth or falsehood of these propositions will be denoted by the binary digits 1 or 0 and the truth or falsehood of 20 propositions will be stored on one line. It is then required to know how many of these propositions are true … 41 Alan Turing and his contemporaries The Ferranti Mark I computer with the operator’s control console between the rows of cabinets holding the logic circuitry. The person standing to the right of the console is Alan Turing. Another new feature was a special hardware random-number generator, suggested by Alan Turing.

By June 1948 the SSEM or ‘Baby’ computer was complete. Two simple test programs were written, one to find the highest common divisor of two numbers and the other to find the highest factor of a number. 5 million instructions. To test the machine, a program was inserted into the store via push buttons and switches. For some days each attempt at a run resulted in failure, usually due to a wiring error. Then, on the morning of Monday 21 June 1948, the highest factor program gave the correct result.
