Introduction By the 1930s, mechanical and electromechanical calculators from Burroughs, Felt & Tarrant, Marchant, Monroe, Remington, Victor, and other manufac- turers had penetrated all aspects of a modern office operations. It seemed that the mathematical tables could handle the rest in science and engineering. However, certain branches of science and engineering reached a calculat- ing barrier that prevented further progress unless an automated method of dealing with complex operations, such as solving linear equalities, differential equations, etc. could be found. What was needed was a new type of a calculating machine that could per- form large-scale error-free calculations by following, in a mechanical way, a predefined sequence of operations, that is, by following a program. The 1930s was a crucial period in the development of computing. Not only the first designs of computers started to appear in Europe and the US but also a groundbreaking theoretical research on computing was initiated. In this lecture we shall take a look at the pioneering work on digital com- puters. We shall discuss the origins of the first computers and their intended use. We shall talk about people and events leading to the first designs and their impact on society and on the development of future computer industry. -

The Early work of Konrad Zuse -- an Historian's View First of all I would like to say that I am honored to have been chosen to give the opening address at this colloquium, and I want to thank the Institut für Informatik of the University of Hamburg not only for their gracious invitation, but also for their decision to honor Herr Doktor Zuse in this way. By their awarding to Konrad Zuse the honorary doctoral degree, they are reaffirming the central fact that science is a cumulative and positive activity of mankind. By all standards of measu- rement, the progress of computer science in the past few decades has been astounding, but we must always remember that we can enjoy that progress only because we have been able to build on the work of pioneers like Dr. -
ROHDE & SCHWARZ NRP-Z22 Datasheet
Test Equipment Solutions Datasheet Test Equipment Solutions Ltd specialise in the second user sale, rental and distribution of quality test & measurement (T&M) equipment. We stock all major equipment types such as spectrum analyzers, signal generators, oscilloscopes, power meters, logic analysers etc from all the major suppliers such as Agilent, Tektronix, Anritsu and Rohde & Schwarz. We are focused at the professional end of the marketplace, primarily working with customers for whom high performance, quality and service are key, whilst realising the cost savings that second user equipment offers. As such, we fully test & refurbish equipment in our in-house, traceable Lab. Items are supplied with manuals, accessories and typically a full no-quibble 1 year warranty. Our staff have extensive backgrounds in T&M, totalling over 150 years of combined experience, which enables us to deliver industry-leading service and support. We endeavour to be customer focused in every way right down to the detail, such as offering free delivery on sales, presenting flexible technical + commercial solutions and supplying a loan unit during warranty repair, if available. As well as the headline benefit of cost saving, second user offers shorter lead times, higher reliability and multivendor solutions. Rental, of course, is ideal for shorter term needs and offers fast delivery, flexibility, try-before-you-buy, zero capital expenditure, lower risk and off balance sheet accounting. Both second user and rental improve the key business measure of Return On Capital Employed. We are based at Aldermaston in the UK from where we supply test equipment worldwide. Our facility incorporates Sales, Support, Admin, Logistics and our own in-house Lab.
