personal computer history

The monitor and I/O devices were sold separately. They are often linked together in networks in larger businesses like chambers of commerce, publishing companies, or schools. A few researchers at places such as SRI and Xerox PARC were working on computers that a single person could use and that could be connected by fast, versatile networks: not home computers, but personal ones. Individual computers as well as computers that are electronically connected via the Internet h…, Wozniak, Stephen Gary They use very little power and had replaced tubes by the early 1960s. By 1976, there were several firms racing to introduce the first truly successful commercial personal computers. The Altair 8800 sold remarkably well even though initial memory size was limited to a few hundred bytes and there was no software available. The internal systems of their automobiles are run by computers. Both used the Intel 8080 CPU. [49] Since the Model II and Model III were already in production Tandy decided to stop manufacturing the Model I. [48] However they remained back-ordered for months, and to ease deliveries they eventually canceled the 4 kB version early the next year. They were operated by specialized technicians, who often dressed in white lab coats and were commonly referred to as a computer priesthood. In the same century Charles Babbage (1792-1871) designed a "Difference Engine" to calculate and print out simple math tables. [66] Toward the end of the 1980s PC XT clones began to take over the home computer market segment from the specialty manufacturers such as Commodore International and Atari that had previously dominated. "[6] In 1977, three new pre-assembled small computers hit the markets which Byte would refer to as the "1977 Trinity" of personal computing. A key difference between Western and Japanese systems at the time was the latter's higher display resolutions (640x400) in order to accommodate Japanese text. Peripheral Component Interconnect (PCI) was released in 1992, and was supposed to replace ISA. [58] Competitors also reduced prices; the Atari 800's price in July was $165,[59] and by the time TI was ready in 1983 to introduce the 99/2 computer—designed to sell for $99—the TI-99/4A sold for $99 in June. In 1984, IBM introduced the IBM Personal Computer/AT (more often called the PC/AT or AT) built around the Intel 80286 microprocessor. They are no longer programmable by the operators and seldom transportable. [46] The 400 and 800 were tweaked into superficially improved models—the 1200XL, 600XL, 800XL, 65XE—as well as the 130XE with 128K of bank-switched RAM. It has become essential in fields of scientific, political, and social research as well as aspects of medicine and law. Enormous changes have come about in the past 30 years as a result of the development of computers in general, and personal computers in particular. Thus, by the end of the nineteenth century, many elements necessary to make a modern computer work were in place: memory cards, input devices, mathematical systems, storage capabilities, power, and input systems. 1982: Machine Wins Over Man. By this time a number of other machines had entered the market. The first model used an audio cassette for external storage, though there was an expensive floppy disk option. The Altair 8800, from Micro Instrumentation Telemetry Systems (MITS) of Albuquerque, NM, was first featured in the January 1975 edition of Popular Electronics. Other previous competition such as Sinclair and Amstrad were no longer in the computer market. The 99/4A had sold for $400 in the fall of 1982, causing a loss for TI of hundreds of millions of dollars. The invention in the late 1970s of local area networks (LANs), notably Ethernet, allowed PCs to communicate with each other (peer-to-peer) and with shared printers. IBM dominated the office equipment industry for nearly 25 years with its calculators, electric typewriters, and time clocks. The transition from a PC-compatible market being driven by IBM to one driven primarily by a broader market began to become clear in 1986 and 1987; in 1986, the 32-bit Intel 80386 microprocessor was released, and the first '386-based PC-compatible was the Compaq Deskpro 386. All the essential parts of a modern personal computer had been invented by the early 1960s. 220–21, History of computing hardware (1960s–present), metal-oxide-semiconductor field-effect transistor, Institut national de la recherche agronomique, Learn how and when to remove this template message, Committee on Foreign Investment in the United States, Synchronous dynamic random-access memory#SDRAM history, Timeline of electrical and electronic engineering, MIT Computer Science and Artificial Intelligence Laboratory, "Restoring the Balance between Analysis and Computation", "Total share: 30 years of personal computer market share figures; The 8-bit era (1980–1984)", "1960 - Metal Oxide Semiconductor (MOS) Transistor Demonstrated", "1971: Microprocessor Integrates CPU Function onto a Single Chip", http://www.digibarn.com/stories/linc/documents/LINC-Personal-Workstation/LINC-Personal-Workstation.pdf, Computer History Museum , Timeline of Computer History, Olivetti Programma 101 is released, "2008/107/1 Computer, Programma 101, and documents (3), plastic / metal / paper / electronic components, hardware architect Pier Giorgio Perotto, designed by Mario Bellini, made by Olivetti, Italy, 1965-1971", "Olivetti Programma 101 Electronic Calculator", "---+ 1000 BiT +--- Computer's description", "3,495,222 PROGRAM CONTROLLED ELECTRONIC COMPUTER", Marek Kępa, The Computer Genius the Communists Couldn't Stand, culture.pl, Aug 7 2017, "SCAMP: The Missing Link In The PC's Past? The NeXTstation was meant to be a new computer for the 1990s, and was a cheaper version of the previous NeXT Computer. Soon it was necessary to create more complex sets of languages and instructions, and this was called software. This led to an explosion of low-cost machines known as home computers that sold millions of units before the market imploded in a price war in the early 1980s. Following this strategy HP became a major player in desktops, laptops, and servers for many different markets. After the 1972 introduction of the Intel 4004, microprocessor costs declined rapidly. Development of the single-chip microprocessor was the gateway to the popularization of cheap, easy to use, and truly personal computers. The company had commissioned Intel, and also Texas Instruments, to develop a single-chip CPU with that same functionality. Apple Computers introduced the Apple II, the first personal computer with color graphics was demonstrated at the West Coast Computer Faire on April 16, 1977, and went on sale on June 10th. Hollerith's company, the Tabulating Machine Company, was the start of the computer business in the United States. Tim Berners-Lee worked at CERN in Switzerland and wrote software in 1989 to enable high-energy physicists to collaborate with physicists anywhere in the world. Human beings have devised many ways to help them do calculations. The first personal computer available for purchase was the Altair 8800. Science and Its Times: Understanding the Social Significance of Scientific Discovery. The cassette option was never popular and was removed in the PC XT of 1983. IBM's pricing was undercut to the point where IBM was no longer the significant force in development, leaving only the PC standard they had established. In Firefox and Chrome, the menu button is represented by three bars stacked on top of each other. These activities have spawned the need for computer security and a new category of technical crime fighters. [64] The XT added a 10MB hard drive in place of one of the two floppy disks and increased the number of expansion slots from 5 to 8. Many valiant knights had challenged Big Blue in the early years, among them Honeywell, Control Data, … Microsoft Corporation was started in 1976 by Bill Gates (1955- ) to create and market software for personal computers. Personal Computer History: 1995-2004 Daniel Knight - 2018.03.05 Although the World Wide Web had been created many years earlier, it was in 1995 that it rocketed into public view. The first programmer was Ada Byron (1815-1852), daughter of the British poet Lord Byron. In 1945, Vannevar Bush published an essay called "As We May Think" in which he outlined a possible solution to the growing problem of information storage and retrieval. [30][31], The Soviet MIR series of computers was developed from 1965 to 1969 in a group headed by Victor Glushkov. Double data rate synchronous dynamic random-access memory (DDR SDRAM) is introduced in 2000. The system's CPU was constructed from roughly a hundred (mostly) TTL logic components, which are groups of gates, latches, counters, etc. Digital electronic computers appeared in 1939 and 1944, but they were only interim steps in computer development. BASIC was the first modern programming language, a simple system that almost anyone could learn. Although the PET and the Apple II offered certain features that were greatly advanced in comparison, Tandy's 3000+ Radio Shack storefronts ensured that it would have widespread distribution that neither Apple nor Commodore could touch. The personal computer has inspired new industries, new companies, and created millionaires and billionaires of their owners. Applications that came with the Macintosh included MacPaint, a bit-mapped graphics program, and MacWrite, which demonstrated WYSIWYG word processing. [7] The Apple II and the PET 2001 were advertised as personal computers,[8][9] while the TRS-80 was described as a microcomputer used for household tasks including "personal financial management". Their knowledge of the home market through the VCS resulted in machines that were almost indestructible and just as easy to use as a games machine—simply plug in a cartridge and go. It enables a user to create written documents, display pictures, sound, play games, make charts, and gain access to the Internet. A new more advanced computer was built in 1951 by Remington Rand Corporation. In spite of a promising start with about 600,000 sold by 1981, they were unable to compete effectively with Commodore's introduction of the Commodore 64 in 1982, and only about 2 million machines were produced by the end of their production run. Marketed as a more sophisticated 32-bit microcomputer for professional users, it used a Motorola 68008 processor. Compared to its predecessor in PC-clones, single data rate (SDR) SDRAM, the DDR SDRAM interface makes higher transfer rates possible by more strict control of the timing of the electrical data and clock signals. At RCA, Joseph Weisbecker designed and built a true home computer known as FRED, but this saw mixed interest from management. With these devices, the working parts of a computer can be contained on a few computer chips. The knowledge obtained was applied a few years later in the development of the successful Programma 101 electronic calculator. The RAM and graphics processors operated at 50 MHz. When IBM finally got into the personal computer market in 1981, it had an immediate impact, even though it had serious limitations. [46][52] The C64 name derived from its 64kb of RAM. Cambridge, MA etc. Through-silicon via is used in High Bandwidth Memory (HBM), a successor of DDR-SDRAM. The combination of the failures of the Sinclair QL computer and the TV80 led to financial difficulties in 1985, and a year later Sinclair sold the rights to their computer products and brand name to Amstrad. Later, a version was available for PCs running DOS. The first was expensive, w… About 180 million PCs (16 percent of the existing installed base) were expected to be replaced and 35 million to be dumped into landfill in 2008. Interestingly, 256 bytes of memory, 8 bit word size, and I/O limited to switches and lights on the front panel, are also the characteristics of the 1975 Altair 8800, whose faith was diametrically opposed to that of the Kenbak. A personal computer is now one that is used by a single operator at a business, a library, or his own home. Acorn was rescued from obscurity, and went on to develop the ARM processor (Acorn RISC Machine) to power follow-on designs. A bus, called Pluribus, was introduced that allowed connection of up to 14 boards. The Commodore PET (Personal Electronic Transactor) introduced. At the height of its success, and largely inspired by the Japanese Fifth Generation Computer programme, the company established the "MetaLab" research centre at Milton Hall (near Cambridge), in order to pursue artificial intelligence, wafer-scale integration, formal verification and other advanced projects. Though the Altair was popular among computer hobbyists, its commercial appeal was limited. researchers, and business travelers, as is the new palm or hand-held computer. Emerging as the dominant force from this battle amongst hardware manufacturers who were vying for market share was the software company Microsoft that provided the operating system and utilities to all PCs across the board, whether authentic IBM machines or the PC clones. It was designed by John V. Blankenbaker. Computer literacy has become a necessary skill for technical or scientific jobs and is becoming a requirement for many jobs, such as bank tellers, salesmen, librarians, and even waiters in restaurants who use computers as part of their daily work. The ZX80 home computer was launched in February 1980 at £79.95 in kit form and £99.95 ready-built. The minicomputer Xerox Alto (1973) was a landmark step in the development of personal computers because of its graphical user interface, bit-mapped high resolution screen, large internal and external memory storage, mouse, and special software.[12]. The 2001 was announced in June 1977 and the first 100 units were shipped in mid October 1977. These tubes commonly powered radios and television sets at the time. Its use has spread to all literate areas of the world, as have communication networks that have few limits. For more information see Synchronous dynamic random-access memory#SDRAM history. However, because it was built for scientists and engineers, it was not available on the general market. Eventually, 5.25 inch floppy drives were made available by Tandy and several third party manufacturers. ." It also traces the evolution of the personal computer from the software hacker, to its use as a consumer appliance on the Internet. The impact of the Apple II and the IBM PC was fully demonstrated when Time named the home computer the "Machine of the Year", or Person of the Year for 1982 (3 January 1983, "The Computer Moves In"). A history of personal computers as told by Lou Frenzel. They have become an appliance that provides entertainment as well as information. The program was typically a small driver for an attached cassette tape reader, which would then be used to read in another "real" program. This chip was much faster, and could address up to 16MB of RAM but only in a mode that largely broke compatibility with the earlier 8086 and 8088. After the job had completed, users could collect the results. Sinclair Research Ltd is a British consumer electronics company founded by Sir Clive Sinclair in Cambridge. The Micro was relatively expensive, which limited its commercial appeal, but with widespread marketing, BBC support and wide variety of programs, the system eventually sold as many as 1.5 million units. Veit, Stan. "Peer to peer" file sharing networks such as Napster, Kazaa and Gnutella arose to be used almost exclusively for sharing music files and became a primary computer activity for many individuals. Drawing upon its predecessor, the Xerox Alto, it was the first commercial system to incorporate various technologies that today have become commonplace in personal computers, including a bit-mapped display, a windows-based graphical user interface, icons, folders, mouse, Ethernet networking, file servers, print servers and e-mail. [78][79], Mainframes, minicomputers, and microcomputers, The beginnings of the personal computer industry, IBM clones, Apple back into profitability. With only 256 bytes of memory, an 8-bit word size, and input and output restricted to lights and switches, and no apparent way to extend its power, the Kenbak-1 was most useful for learning the principles of programming but not capable of running application programs. In 1975, Ed Roberts coined the term "personal computer" when he introduced the Altair 8800. IBM manufactured its first large mainframe computer in 1952 and offered it for sale to companies, governments, and the military. The ZX Spectrum was launched on 23 April 1982, priced at £125 for the 16 KB RAM version and £175 for the 48 KB version. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates. This innovation continued to shrink the size of computers. But because of these shortcuts that IBM took to enter the market quickly, they ended up releasing a product that was easily copied by other manufacturers using off the shelf, non-proprietary parts. In 1982, the TI 99/4A and Atari 400 were both $349, Radio Shack's Color Computer sold at $379, and Commodore had reduced the price of the VIC-20 to $199 and the Commodore 64 to $499. 5.1.2 Intel 4004 Dennis Hayes and Dale Heatherington released the 80-103A Modem, the first Modem for the home user. The processor card, keyboard, monitor and cassette drive were all mounted in a single metal case. IBM rebranded it as PC DOS, while Microsoft sold variations and upgrades as MS-DOS. This computer, which used Intel Corporation ’s 8080 microprocessor, was developed in 1974. The genesis of the modern computing machine came in 1888 when Herman Hollerith (1860-1929), an American inventor, devised a calculating machine to tabulate the U.S. Census for 1890. Due to the sales growth of IBM clones in the '90s, they became the industry standard for business and home use. MS-DOS – Microsoft Disk Operating System (1981) Originally developed by Microsoft for IBM, MS-DOS was the standard operating system for IBM-compatible personal computers. VLB importantly offered a less costly high speed interface for consumer systems, as only by 1994 was PCI commonly available outside of the server market. End users generally did not directly interact with the machine, but instead would prepare tasks for the computer on off-line equipment, such as card punches. The Model I could not meet FCC regulations on radio interference due to its plastic case and exterior cables. 21 Dec. 2020 . "Gus" Roche, an all-but-forgotten engineer in San Antonio who was obsessed with creating a personal computer. The system, made entirely with transistors for high performance, was conceived, designed and developed by a small group of researchers led by Mario Tchou (1924–1961). United States had received 38.8 percent (394 million) of the computers shipped, Europe 25 percent and 11.7 percent had gone to Asia-Pacific region, the fastest-growing market as of 2002. TI designed a chip rather quickly, based on Intel's early drawings. Although the first personal computer is considered by many to be the KENBAK-1, which was first introduced for $750 in 1971. The BBC became interested in running a computer literacy series, and sent out a tender for a standardized small computer to be used with the show. The importance and impact of the personal computer by the beginning of the twenty-first century rests in one part on the development of the computer and in another on the creation of a new system of communications—the Internet—that depends on personal computers and could not have become so widespread without them. Stan Veit's History of the Personal Computer. The first personal computer that was fully assembled and offered for sale on the general market was Apple I. Some of the early LINC computers were assembled from kits of parts by the end users. At the time of its introduction K-202 was the fastest PC computer in the world capable of performing one million operations per second. (See List of early non-IBM-PC-compatible PCs.) Multi-core processors can be programmed and reasoned about using symmetric multiprocessing (SMP) techniques known since the 60s (see the SMP article for details). ""The enduring American love affairs with the automobile and the television set are now being transformed into a giddy passion for the personal computer," gushed the story — written on a typewriter — in the Jan. 3, 1983, issue, a year and a half after IBM … These computers look and behave like personal computers even when they are linked to large computers or networks. Up to that time computers had been very large and expensive, operated mainly by big companies. Its other strong features were its full stroke QWERTY keyboard, small size, well written Microsoft floating-point BASIC and inclusion of a monitor and tape deck for approximately half the cost of the Apple II. These CPUs were usually made by a third party such as Cyrix or AMD. But it did have the magic letters on the front—IBM. Therefore, that information is unavailable for most Encyclopedia.com content. It came in kit form ready to be assembled and was aimed at hobbyists who liked to build their own radios and other electronic devices. He designed the Analytical Engine and it was this design that the basic framework of the computers of today are based on. Released in December 1996, ACPI replaced Advanced Power Management (APM), the MultiProcessor Specification, and the Plug and Play BIOS (PnP) Specification.[70]. As computers increased in power, speed, and the variety of functions they performed, the size and complexity of programs also expanded. During the 1990s, the Macintosh remained with a low market share, but as the primary choice for creative professionals, particularly those in the graphics and publishing industries. Only 30 units of K-202 were ever produced and the company was shut down by a decree of communist regime.[33]. This led to a wide variety of systems based on the S-100 bus introduced with the Altair, machines of generally improved performance, quality and ease-of-use. Before the creation of the modern large computer and its refinement, the personal computer, a number of discoveries and inventions were necessary. Now vertically integrated,[56] Commodore lowered the retail price of the 64 to $300 at the June 1983 Consumer Electronics Show, and stores sold it for as little as $199. Steve Wozniak (known as "Woz"), a regular visitor to Homebrew Computer Club meetings, designed the single-board Apple I computer and first demonstrated it there. First-generation ACPI hardware had issues. Although the PC and XT included a version of the BASIC language in read-only memory, most were purchased with disk drives and run with an operating system; three operating systems were initially announced with the PC. When sold by Microsoft, PC DOS was called MS-DOS. The first automatic calculator appeared in the seventeenth century, using wheels and gears to do calculations. They have altered the focus in boardrooms from the people who procure money to those who create or make decisions about new product. The personal computer revolution Before 1970, computers were big machines requiring thousands of separate transistors. Therefore, they were accessible for individual laboratories and research projects. Japanese computers also employed Yamaha FM synthesis sound boards since the early 1980s which produce higher quality sound. Also in the early 21st century, LCD monitors became the most popular technology for computer monitors, with CRT production being slowed down. NVIDIA bought 3dfx in 2000. Three machines, the Apple II, PET 2001 and TRS-80 were all released in 1977,[41] becoming the most popular by late 1978. Some computers were designed for the knowledgeable hobbyist, while others followed the lead of Apple. By today's standards, they were very large (about the size of a refrigerator) and cost prohibitive (typically tens of thousands of US dollars). The Olivetti Programma 101 was presented at the 1965 New York World's Fair after 2 years work (1962- 1964). In Internet Explorer, click the star icon in the upper-right corner and select the tab labeled History. [35] The requirements of the Datapoint 2200 determined the 8008 architecture, which was later expanded into the 8080 and the Z80 upon which CP/M was designed. While the original PC design could accommodate only up to 64k on the main board, the architecture was able to accommodate up to 640KB of RAM, with the rest on cards. IMSAI 8080 The First Clone The Web has multimedia capabilities, provides pictures, sound, movement, and text. It used the Intel 8088 CPU running at 4.77 MHz, containing 29,000 transistors. With less competition than ever before, Dell rose to high profits and success, introducing low cost systems targeted at consumers and business markets using a direct-sales model. Its higher price and lack of floating point BASIC, along with a lack of retail distribution sites, caused it to lag in sales behind the other Trinity machines until 1979, when it surpassed the PET. [76] The third quarter of 2008 marked the first time laptops outsold desktop PCs in the United States. This creation ranks as one of the most important inventions of the twentieth century. The history of the personal computer as mass-market consumer electronic devices effectively began in 1977 with the introduction of microcomputers, although some mainframe and minicomputers had been applied as single-user systems much earlier. Byte in January 1980 announced in an editorial that "the era of off-the-shelf personal computers has arrived". Kildall's wife and business partner, Dorothy McEwen, met with the IBM representatives who were unable to negotiate a standard non-disclosure agreement with her. Window 95 shipped in August, and Intel unveiled the Pentium Pro in November. The advent of microprocessors, which included all the basic functions of computers on a single chip, brought prices down and expanded the market. Another popular use of CD ROMs in the 1990s was multimedia, as many desktop computers started to come with built-in stereo speakers capable of playing CD quality music and sounds with the Sound Blaster sound card on PCs. When Hollerith sold out in 1911, the name was changed to the Computing-Tabulating-Recording Machine Company. 1981: The first IBM personal computer, code-named "Acorn," is introduced. It is made up of a series of electronic addresses or web sites. The Soul of a New Machine. It uses Microsoft's MS-DOS operating system. IBM will have a 19% stake in Lenovo, which will move its headquarters to New York State and appoint an IBM executive as its chief executive officer. Although the design of the Datapoint 2200's TTL based bit serial CPU and the Intel 8008 were technically very different, they were largely software-compatible.
