UIS5077779 Electronic Calculators Components from the Harvard Mark I computer, 1937-1944. Electromagnetic counters from the IBM Automatic Sequence Control Calculator (ASCC), more commonly known as the Harvard Mark I. This was the first digital computer and was designed and constructed in the United States by the IBM Corporation between 1937 and 1944. It was based on a proposal by H H Aiken of Harvard University, Massachusetts. Counters were used to store decimal numbers and relays for control and switching. The computer was composed of a series of calculators which each worked on different parts of a problem, supervised by a central control unit. The machine was made up of over 750,000 components and weighed 5 tons. It was mainly used for making scientific calculations in the fields ofÊ ballistics and ship design. ©SSPL/Science Museum

UIS5069876 Computer Components (composant electronique) Mullard circuit blocks, 1965. Made by the British company Mullard Ltd, these devices are complete electronic circuits, consisting of components sealed into boxes, which carry out specific logical and data-control functions. Circuit blocks were the first commercially available 'potted circuits' whose operation did not need to be understood in order to be used in an electrical system. The use of circuit blocks and, later, integrated circuits has led to standardisation, miniaturisation and modularity of electronic system design. ©SSPL/Science Museum

UIS5069562 Computer Components (composant - circuit electronique) Two printed circuit boards, c 1970s. Printed circuit boards such as these are composed of an electronic circuit based on thin strips of a conductor on an insulating board. The foil is etched away to leave tracks that connect the components together. A layer of lacquer protects the board except where components are inserted. This allows the components to be fixed in place by skimming the entire board across a bath of molten solder. ©SSPL/Science Museum

UIS5073113 Young female electronics worker and inspector (inspecteur), 1952. The woman whose work is being inspected is making components for cathode ray tubes at Mullard¿s Blackburn unit and is one of 20,000 employees nationwide, this included 800 graduate scientists. Mullards was a leading company within the burgeoning UK electronics industry, their products ranged from basic components such as valves and transistors to highly sophisticated electronic research services.

UIG3479280 New telephone exchange system repairs itself or calls for help. Printed circuit board: a technician inserts a printed circuit board into place in the new U.S telephone exchange system. Thousands of the boards are used in a central telephone exchange. Mounted on the boards are transistors, semiconductor diodes and other electronic components, and metal 'teeth' on this end of the board make electrical connection with the rest of the equipment.

UIS5077690 Electronic Calculators Sinclair Cambridge pocket calculator, 1973. This model was one of a series of small calculators developed by the British inventor, Sir Clive Sinclair (1940-) in the early 1970s. These were the first calculators that were designed to be small and light enough to fit in the pocket. This Cambridge calculator was sold both as a kit and fully built. Although it was expensive when it was first produced, its price soon dropped. When first introduced in 1973, the cost was £29.95, but by 1974 a built unit cost £21, and a year later the price had fallen to below £15. The Cambridge calculator was small, even by modern standards, weighing only 3.5oz (99g). It suffered from a design flaw; after a certain amount of use, the calculator was impossible to turn off due to oxidation of cheap components used in the switch contacts. ©SSPL/Science Museum

PIX4603537 The Orion MPVC module - artist view - Orion spacecraft exploded view - Ecorchee view of the module lives in Orion. This module is intended to take a crew to the Moon where asteroides will also be used to commute with the space station. An artist's impression of the Orion spacecraft and its components including ESA's service module. The Crew Module sits atop the service module and can hold four astronauts and cargo. This the only part of Orion designed to reenter Earth's atmosphere: the heatshield protects it against the intense heat of reentry at 32,000 km/h. The European Service Module (ESM) provides electricity, propulsion, air and water, and forms part of the vehicle's structure, like a car chassis. More information about the module is given on separate pages to the left. A Crew Module Adapter (CMA) connects the capsule to the ESM. It houses electronic equipment for communications, power and control, and includes a bridge that connects electrical, data and fluid systems between the main modules. A number of elements are required only during launch and are discarded shortly before entering space. The Spacecraft Adapter attachments Orion to its launch vehicle. The Spacecraft Adapter Jettisonable Fairings offer aerodynamic protection during launch. When the vehicle is high enough above Earth, the fairings are jettisoned to fall into the ocean. As Orion ferries people to space and back, safety is paramount. If anything were to go wrong during launch, an abort will propel the crew capsule up and away from the danger, returning it to the ground by parachute. The Launch Aort System forms the nose of the complete launcher and has rockets of its own that fire in an emergency. It, too, is discarded at altitude
