Le premier PC IBM a fonctionné sur un microprocesseur Intel 8088 à 4,77 MHz. Il disposait, selon les modèles, d'aucun, d'un ou deux lecteurs de disquettes 5 pouces 1/4 de 160 ko simple face, 320 ko double face, 512 ko double face double densité. Second, any ports the card provides for external attachment are bolted to the bracket, keeping them secured in place as well. En 1981, IBM a produit l'IBM PC. Si on considère le Manchester Mark I comme le premier vrai ordinateur (juin 1948), son successeur a été l'ENIAC, créé en septembre 1948. Selon le Musée d'Histoire de l'ordinateur, en 1970, le Kenbak - 1 était le premier ordinateur personnel fait . The PC motherboard included a second, empty socket, described by IBM simply as an "auxiliary processor socket," although the most obvious use was the addition of an Intel 8087 math coprocessor, which improved floating-point math performance. In its application to computing, it was coined by the professor of philology Jacques Perret in a letter dated 16 April 1955, in response to a request from IBM France, who believed the word calculateurwas too restrictive in light of the possibilities of these machines (this is a very rare example of the creation of a neologism authenticated by dated letter). Communément appelé « micro-ordinateur », l’ordinateur personnel compte parmi les appareils que les gens utilisent quotidiennement, à la maison comme au bureau. IBM répliqua avec les 3270 PC/G et 3270 PC/GX, supportant les fonctionnalités semi-graphiques et couleur des 3279. Its ROM BASIC supported the cassette tape interface, but PC DOS did not, limiting use of that interface to BASIC only. L ' IBM 5100 Portable Computer Il a été le premier ordinateur personnel commercialisé par 'IBM. After the XT was released, IBM altered the design of the 5150 to add most of these capabilities, except for the upgraded power supply. 10 William C. Lowe est à l’origine du premier « personal computer » ou PC d’IBM. $12.50 Ship International. [31] One publication counted 753 software packages available a year after the PC's release, four times as many as the Macintosh had a year after release. Most expansion cards have a matching metal bracket which slots into one of these openings, serving two purposes. IBM 701. Many IBM PCs remained in service long after their technology became largely obsolete. Un constructeur extérieur développa la carte IRMA transformant le PC en écran 3270. Le 14 août 2001 à 00h00.

The software and hardware of the PC, at release, was designed around a single 8-bit adaptation of the ASCII character set, now known as code page 437. IBM referred to these as "I/O slots," but after the expansion of the PC clone industry they became retroactively known as the ISA bus. Le 12 août 1981 naissait à New York le premier ordinateur personnel : le personal computer 51-50 d’IBM. Market research found that computer dealers were very interested in selling an IBM product, but they insisted the company use a design based on standard parts, not IBM-designed ones, so that stores could perform their own repairs rather than requiring customers to send machines back to IBM for service. Page 4 Note Before using this information and the product it supports, be sure to read the general information under “Notices” at the back of this manual. Le premier ordinateur personnel L’un des premiers ordinateurs personnels est créé en 1981 par la compagnie IBM et est appelé PC ( Personal Computer ). The 8088 had the advantage that IBM already had familiarity with it from designing the IBM System/23 Datamaster. The MOS 6502 was introduced at a conference in San Francisco at a cost of $25, far less than comparable processors from Intel and Motorola, leading some attendees to believe that the company was perpetrating a hoax. Connectivity to other computers and peripherals was initially provided through serial and parallel ports. L’ordinateur était un code appelé parfois Acorn et avait un processeur 8088, 16 Ko de mémoire, extensible à 256 et utilisant MS-DOS. The idea of acquiring Atari was considered, but rejected in favor of a proposal by Lowe that by forming an independent internal working group and abandoning all traditional IBM methods, a design could be delivered within a year, and a prototype within 30 days.

[60], At release, IBM did not offer any hard disk drive option[52] and adding one was difficult - the PC's stock power supply had inadequate power to run a hard drive, the motherboard did not support BIOS expansion ROMs which was needed to support a hard drive controller, and both PC DOS and the BIOS had no support for hard disks. The design was essentially complete by April 1981, when it was handed off to the manufacturing team. IBM chose the 8088 over the similar but superior 8086 because Intel offered a better price for the former and could provide more units,[19] and the 8088's 8-bit bus reduced the cost of the rest of the computer.

Fruit du travail d’une petite équipe d’ingénieur, l’appareil fonctionnait à l’époque avec un lecteur de disquettes, c’est le début de la révolution informatique. [52] The CPU is clocked at 4.77 MHz, which would eventually become an issue when clones and later PC models offered higher CPU speeds that broke compatibility with software developed for the original PC. These machines became known as IBM compatibles or "clones," and software was widely marketed as compatible with "IBM PC or 100% compatible." IBM rectified these problems in the later XT, which included more slots and support for an internal hard drive, but at the same time released the 5161 Expansion Unit, which could be used with either the XT or the original PC. Il comportait un microprocesseur Intel 8088 cadencé à 4,77 MHz et une mémoire vive de 16 ko pouvant être portée à 256 ko.
