John Napier, the inventor of logarithms, also invented this aid to calculation known as 'Napier's Bones' in 1617. The 'bones' consist of a set of rectangular rods, each marked with a counting number at the top, and the multiples of that number down their lengths. When aligned against the row of multiples as shown, any multiple of the top number can be read off from right to left by adding the digits in each parallelogram in the appropriate row. Multiplication is thus reduced to addition.

This is the earliestearliest-known dated straight slide rule. When logarithms were invented in 1614 they stimulated new designs of instrument to exploit their usefulness. The slide rule was the most enduring of these. Introduced in a circular form in 1622, it survived as a tool of engineers and scientists until the 1970s. The use of logarithmic scales reduces multiplication and division to addition and subtraction respectively. Bissaker worked in Radcliffe, now east London, specialising in wooden instruments for seamen and navigators.

Satu contoh populer dari konsep ini diciptakan oleh seorang Perancis Joseph Marie Jacquard (1752(1752-1834), untuk mengontrol mesin tenun secara otomatis Program ini berupa lempengan baja berlubang untuk memposisikan benang dalam proses tenun Mesin tenun semacam ini masih digunakan sampai sekarang dan dikontrol dengan program yang disimpan di disket, bukan dengan lempeng baja lagi.

The Manchester Differential Analyser is an analogue computer designed to solve a class of mathematical functions called differential equations. This machine was built by the MetropolitanMetropolitan-Vickers Electrical Company and completed in 1935 for the Physics Department at Manchester University. The machine was based on an American design, powered by electric motors, and uses mechanical components to model mathematical relationships. The central device is a discdisc-andand-wheel device integrator which performs mathematical integration.

Charles Babbage's calculating engines are among the most celebrated icons in the prehistory of computing. His Difference Engine No. 1 was the first successful automatic calculator and remains one of the finest examples of precision engineering of the time. The portion shown was assembled in 1832 by Babbage's engineer, Joseph Clement. It consists of about 2000 parts and represents oneone-seventh of the complete engine. This 'finished portion of the unfinished engine' was demonstrated to some acclaim by Babbage, and functions impeccably to this day. The engine was never completed and most of the 12 000 parts manufactured were later melted for scrap.

Hollerith's punch cards and tabulating machines were a step toward automated computation. His device could automatically read information which had been punched onto card. He got the idea and then saw Jacquard's punchcard. Punch card technology was used in computers up until the late 1970s. Computer "punched cards" were read electronically, the cards moved between brass rods, and the holes in the cards, created a electric current where the rods would touch.

komputer elektronis paling awal diciptakan oleh John Atanasoff di Iowa State Univ. (1939, 1942) komputer elektronis awal yang paling terkenal adalah ENIAC (Electronic Numerical Integrator and Computer) dibangun pada tahun 1946 oleh J.P. Eckert, Eckert, J.W.

The ENIAC machine occupied a room thirty by fifty feet. The controls are at the left, and a small part of the output device is seen at the right. The two men in uniform were being trained to maintain the machine after it was turned over to the Ordnance Department (which sponsored the development of the ENIAC). The two women were assistants on the staff of the Moore School who helped program the ENIAC.

The first UNIVAC computer was delivered to the Census Bureau in June 1951. Unlike the ENIAC, the UNIVAC processed each digit serially. But its much higher design speed permitted it to add two tenten-digit numbers at a rate of almost 100,000 additions per second. Internally, the UNIVAC operated at a clock frequency of 2.25 MHz, which was no mean feat for vacuum tube circuits.

Program yang mengontrol ENIAC dibuat dengan cara mengubah kabelkabel-kabel yang ada didalamnya Proses ini sangat rumit dan menghabiskan waktu, kadang dibutuhkan beberapa orang dan beberapa hari untuk mengubah kabelkabel-kabel tsb. Selama itu pula komputer tidak bisa dimanfaatkan Pada masa itu, perintah komputer disimpan di luar komputer berupa “punch card” atau media lain, dan diproses komputer satu per satu untuk diterjemahkan komputer dan dieksekusi.

Apple II 1977

In 1957, Ken Olsen and Harlan Anderson founded a company called Digital Equipment Corporation (DEC) with the goal of manufacturing and selling highhighspeed digital circuits. By 1959, the company was well established, and it introduced its first computer, the PDPPDP-1 (The letters stood for "Programmed Data Processor"). The PDP1 incorporated PDP some of the engineering advances that would later characterize minicomputers, especially in its internal design and attractive packaging.

Radio Shack TRS-80, 1977 Built in 1977, the Apple II was based on Wozniak's Apple I design, but with several additions. The first was the design of a plastic case-a rarity at the time-which case--a time--which was painted beige. The second was the ability to display color graphics-a holy graphics--a grail in the industry. The Apple II also included a larger ROM, more expandable RAM (4K to start), and 8 expansion slots. It had integer BASIC hardhard-coded on the ROM for easier programming, and included two game paddles and a demo cassette for $1,298. In early 1978 Apple also released a disk drive for the machine, one of the most inexpensive available. The Apple II remained on the Apple product list until 1980. It was also repackaged in a black case and sold to educational markets by Bell & Howell.

… Eventually the company relented and in the summer of 1977 introduced the TRSTRS-80, at a base price of only $400. It was indeed a complete machine, although the base model had only 4K bytes of memory and could not handle lowercase letters. One could expand its storage and input/output by purchasing an Expansion Interface at additional cost. But it did work as advertised, and the TRSTRS-80 easily met Tandy's sales projections. The company soon introduced advanced models with more internal memory and disk drives instead of cassettes for entering programs. Ir. Djoko Luknanto, M.Sc., Ph.D. mailto:[email protected]
