Le 12 ao\u00fbt 1981, IBM commercialisait l’IBM 5150, et si la machine ne payait clairement pas de mine avec sa robe uniform\u00e9ment beige, elle a chang\u00e9 la micro-informatique \u00e0 jamais\u2026 et ce n’est pas une vue de l’esprit.<\/strong><\/p>\n\n\n\n

Un processeur Intel plut\u00f4t qu’IBM<\/h2>\n\n\n\n

Si l’IBM 5150 est rapidement devenu IBM PC – pour personal computer<\/em> – dans le langage courant, la firme am\u00e9ricaine n’est pourtant pas \u00e0 l’origine du concept d’ordinateur personnel. D’autres soci\u00e9t\u00e9s comme Commodore ou Apple \u00e9taient plus en vue sur ce segment du march\u00e9.<\/p>\n\n\n\n

Pour sa premi\u00e8re machine \u00ab personnelle \u00bb, IBM avait d’ailleurs surpris son monde en choisissant le processeur Intel 8088 plut\u00f4t que la solution RISC d\u00e9velopp\u00e9e en interne. Cadenc\u00e9e \u00e0 4,77 MHz, la b\u00eate \u00e9tait \u00e9paul\u00e9e par 16 Ko de m\u00e9moire vive\u2026 et tournait sous PC-DOS 1.0, l’OS fournit par Microsoft qui, de fait, c\u00e9l\u00e8bre aussi ses 40 ans.<\/p>\n\n\n\n

Des bases pos\u00e9es pour plus de 40 ans<\/h2>\n\n\n\n

Premier atout de l’IBM 5150, la m\u00e9moire vive pouvait passer \u00e0 64 Ko voire m\u00eame 256 Ko gr\u00e2ce \u00e0 des emplacements disponibles et c’est pr\u00e9cis\u00e9ment cette ouverture de la plateforme qui a fait le succ\u00e8s de ce premier PC. Ainsi, la carte m\u00e8re disposait de quatre ports d’extension, \u00e0 la norme ISA ou Industry Standard Architecture<\/em>, un acronyme bien connu des plus anciens d’entre nous.<\/p>\n\n\n\n

Ce choix d’ouverture technique a permis la naissance d’un immense march\u00e9 pour des cartes d’extension en tout genres. Cela a aussi ouvert la voie \u00e0 la multiplication des clones. Dans un premier temps, IBM en a largement profit\u00e9 et son IBM 5150 a d\u00e9pass\u00e9 toutes les esp\u00e9rances en termes de ventes, notamment gr\u00e2ce \u00e0 un co\u00fbt relativement faible – pour l’\u00e9poque – au regard de la concurrence.<\/p>\n\n\n\n

L’IBM 5150 a finalement termin\u00e9 sa carri\u00e8re en 1987 apr\u00e8s six ans de bons et loyaux services. Il a surtout impos\u00e9 les bases de ce qui fait un PC encore aujourd’hui avec ce processeur x86 au c\u0153ur de la machine, cette ouverture qui permet de faire \u00e9voluer la b\u00eate et cet OS sign\u00e9 Microsoft que l’on parle de PC-DOS \/ MS-DOS ou de Windows.<\/p>\n\n\n\n
