The world's first modern computer, built in Manchester England in 1948, was followed remarkably swiftly by the first business software, but by 1968 software was in crisis and NATO called a conference. The problems were diagnosed, solutions were proposed - and largely ignored. A second Software Crisis was announced in the early 1980's and again the effective solutions were considered impractical and the practical solutions were largely ineffective. Meanwhile as Moore's Law predicted, hardware costs continued to fall exponentially, making software systems ubiquitous and leading to a third software crisis, this time of cybersecurity.

Preprints zur Kulturgeschichte der Technik

David Gugerli , Daniela Zetti

The historicization of the computer in the second half of the 20th century can be understood as the effect of the inevitable changes in both its technological and narrative development. What interests us is how past futures and therefore history were stabilized. The development, operation, and implementation of machines and programs gave rise to a historicity of the field of computing. Whenever actors have been grouped into communities – for example, into industrial and academic developer communities – new orderings have been constructed historically. Such orderings depend on the ability to refer to archival and published documents and to develop new narratives based on them. Professional historians are particularly at home in these waters – and nevertheless can disappear into the whirlpool of digital prehistory. Toward the end of the 1980s, the first critical review of the literature on the history of computers thus offered several programmatic suggestions. It is one of the peculiar coincidences of history that the future should rear its head again just when the history of computers was flourishing as a result of massive methodological and conceptual input. The emergence of the World Wide Web in the 1990s, which caught historians totally by surprise, led to an ahistorical, anthropological, aesthetic-medial approach to digitization. The program for investigating the prehistory of the digital age was rewritten in favor of explaining the development of communication networks. Computer systems and their concepts dropped out of history. This poses a problem for the history of computers, insofar as the success of the history of technology is tied to the stability of its objects. It seems more promising to us to not attribute the problem to the object called computer or to the “disciplinary” field, but rather to focus entirely on substantive issues. An issue-oriented technological history of the 21st century should be able to do this by treating the history of computers as a refreshing source of productive friction.

ABACUS 4th Century B.C. • The abacus, a simple counting aid, may have been invented in Babylonia (now Iraq) in the fourth century B.C. • This device allows users to make computations using a system of sliding beads arranged on a rack.

BLAISE PASCAL (1623 - 1662) • In 1642, the French mathematician and philosopher Blaise Pascal invented a calculating device that would come to be called the "Adding Machine".

BLAISE PASCAL (1623 - 1662) • Originally called a "numerical wheel calculator" or the "Pascaline", Pascal's invention utilized a train of 8 moveable dials or cogs to add sums of up to 8 figures long. As one dial turned 10 notches - or a complete revolution - it mechanically turned the next dial. • Pascal's mechanical Adding Machine automated the process of calculation. Although slow by modern standards, this machine did provide a fair degree of accuracy and speed.

CHARLES BABBAGE (1791 - 1871) • Born in 1791, Charles Babbage was an English mathematician and professor. • In 1822, he persuaded the British government to finance his design to build a machine that would calculate tables for logarithms. • With Charles Babbage's creation of the "Analytical Engine", (1833) computers took the form of a general purpose machine.

HOWARD AIKEN (1900 - 1973) • Aiken thought he could create a modern and functioning model of Babbage's Analytical Engine. • He succeeded in securing a grant of 1 million dollars for his proposed Automatic Sequence Calculator; the Mark I for short. From IBM. • In 1944, the Mark I was "switched" on. Aiken's colossal machine spanned 51 feet in length and 8 feet in height. 500 meters of wiring were required to connect each component.

HOWARD AIKEN (1900 - 1973) • The Mark I did transform Babbage's dream into reality and did succeed in putting IBM's name on the forefront of the burgeoning computer industry. From 1944 on, modern computers would forever be associated with digital intelligence.

ENIAC 1946 • Electronic Numerical Integrator And Computer • Under the leadership of J. Presper Eckert (1919 - 1995) and John W. Mauchly (1907 - 1980) the team produced a machine that computed at speeds 1,000 times faster than the Mark I was capable of only 2 years earlier. • Using 18,00-19,000 vacuum tubes, 70,000 resistors and 5 million soldered joints this massive instrument required the output of a small power station to operate it.

ENIAC 1946 • It could do nuclear physics calculations (in two hours) which it would have taken 100 engineers a year to do by hand. • The system's program could be changed by rewiring a panel.

TRANSISTOR 1948 • In the laboratories of Bell Telephone, John Bardeen, Walter Brattain and William Shockley discovered the "transfer resistor"; later labelled the transistor. • Advantages: • increased reliability • 1/13 size of vacuum tubes • consumed 1/20 of the electricity of vacuum tubes • were a fraction of the cost

TRANSISTOR 1948 • This tiny device had a huge impact on and extensive implications for modern computers. In 1956, the transistor won its creators the Noble Peace Prize for their invention.

ALTAIR 1975 • The invention of the transistor made computers smaller, cheaper and more reliable. Therefore, the stage was set for the entrance of the computer into the domestic realm. In 1975, the age of personal computers commenced. • Under the leadership of Ed Roberts the Micro Instrumentation and Telemetry Company (MITS) wanted to design a computer 'kit' for the home hobbyist.

ALTAIR 1975 • Based on the Intel 8080 processor, capable of controlling 64 kilobyes of memory, the MITS Altair - as the invention was later called - was debuted on the cover of the January edition of Popular Electronics magazine. • Presenting the Altair as an unassembled kit kept costs to a minimum. Therefore, the company was able to offer this model for only $395. Supply could not keep up with demand.

ALTAIR 1975 • ALTAIR FACTS: • No Keyboard • No Video Display • No Storage Device

IBM (PC) 1981 • On August 12, 1981 IBM announced its own personal computer. • Using the 16 bit Intel 8088 microprocessor, allowed for increased speed and huge amounts of memory. • Unlike the Altair that was sold as unassembled computer kits, IBM sold its "ready-made" machine through retailers and by qualified salespeople.

IBM (PC) 1981 • To satisfy consumer appetites and to increase usability, IBM gave prototype IBM PCs to a number of major software companies. • For the first time, small companies and individuals who never would have imagined owning a "personal" computer were now opened to the computer world.

MACINTOSH (1984) • IBM's major competitor was a company lead by Steve Wozniak and Steve Jobs; the Apple Computer Inc. • The "Lisa" was the result of their competitive thrust. • This system differed from its predecessors in its use of a "mouse" - then a quite foreign computer instrument - in lieu of manually typing commands. • However, the outrageous price of the Lisa kept it out of reach for many computer buyers.

MACINTOSH (1984) • Apple's brainchild was the Macintosh. Like the Lisa, the Macintosh too would make use of a graphical user interface. • Introduced in January 1984 it was an immediate success. • The GUI (Graphical User Interface) made the system easy to use.

MACINTOSH (1984) • The Apple Macintosh debuts in 1984. It features a simple, graphical interface, uses the 8-MHz, 32-bit Motorola 68000 CPU, and has a built-in 9-inch B/W screen.

Computer Generations

FIRST GENERATION (1945-1956) • First generation computers were characterized by the fact that operating instructions were made-to-order for the specific task for which the computer was to be used. Each computer had a different binary-coded program called a machine language that told it how to operate. This made the computer difficult to program and limited its versatility and speed. Other distinctive features of first generation computers were the use of vacuum tubes (responsible for their breathtaking size) and magnetic drums for data storage.

SECOND GENERATION (1956-1963) • Throughout the early 1960's, there were a number of commercially successful second generation computers used in business, universities, and government from companies such as Burroughs, Control Data, Honeywell, IBM, Sperry-Rand, and others. These second generation computers were also of solid state design, and contained transistors in place of vacuum tubes.

SECOND GENERATION (1956-1963) • They also contained all the components we associate with the modern day computer: printers, tape storage, disk storage, memory, operating systems, and stored programs. One important example was the IBM 1401, which was universally accepted throughout industry, and is considered by many to be the Model T of the computer industry. By 1965, most large business routinely processed financial information using second generation computers.

THIRD GENERATION (1965-1971) • Though transistors were clearly an improvement over the vacuum tube, they still generated a great deal of heat, which damaged the computer's sensitive internal parts. The quartz rock eliminated this problem. Jack Kilby, an engineer with Texas Instruments, developed the integrated circuit (IC) in 1958. The IC combined three electronic components onto a small silicon disc, which was made from quartz. Scientists later managed to fit even more components on a single chip, called a semiconductor.

THIRD GENERATION (1965-1971) • As a result, computers became ever smaller as more components were squeezed onto the chip. Another third-generation development included the use of an operating system that allowed machines to run many different programs at once with a central program that monitored and coordinated the computer's memory.

FOURTH GENERATION (1971-Present) • In 1981, IBM introduced its personal computer (PC) for use in the home, office and schools. The 1980's saw an expansion in computer use in all three arenas as clones of the IBM PC made the personal computer even more affordable. The number of personal computers in use more than doubled from 2 million in 1981 to 5.5 million in 1982.

FOURTH GENERATION (1971-Present) • Ten years later, 65 million PCs were being used. Computers continued their trend toward a smaller size, working their way down from desktop to laptop computers (which could fit inside a briefcase) to palmtop (able to fit inside a breast pocket). In direct competition with IBM's PC was Apple's Macintosh line, introduced in 1984. Notable for its user-friendly design, the Macintosh offered an operating system that allowed users to move screen icons instead of typing instructions

FIFTH GENERATION (Future) • Many advances in the science of computer design and technology are coming together to enable the creation of fifth-generation computers. Two such engineering advances are parallel processing, which replaces von Neumann's single central processing unit design with a system harnessing the power of many CPUs to work as one. Another advance is superconductor technology, which allows the flow of electricity with little or no resistance, greatly improving the speed of information flow.

FIFTH GENERATION (Future) • Computers today have some attributes of fifth generation computers. For example, expert systems assist doctors in making diagnoses by applying the problem-solving steps a doctor might use in assessing a patient's needs. It will take several more years of development before expert systems are in widespread use.
