L'azienda si occupava di sistemi molto più potenti e costosi e trattava con istituzioni e grandi imprese, e la fascia delle macchine personali da poche migliaia di dollari, sebbene già esistente da metà anni '70, non era economicamente di suo interesse. Tuttavia da qualche anno i personal computer erano in rapida ascesa, specialmente dopo l'ingresso nel 1977 dei più piccoli e più agili concorrenti <a href="/wiki/Apple" title="Apple">Apple</a>, <a href="/wiki/Commodore" class="mw-redirect" title="Commodore">Commodore</a> e <a href="/wiki/Tandy_Corporation" title="Tandy Corporation">Tandy</a>, perciò IBM decise infine di entrare anche in quel segmento.<sup id="cite_ref-RC49_5-0" class="reference"><a href="#cite_note-RC49-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> </p><p>L'azienda aveva già prodotto personal computer, a partire dal trasportabile <a href="/wiki/IBM_5100" title="IBM 5100">IBM 5100</a> (1975), poi seguito da una linea di vari successori, ma si trattava di macchine dal costo molto elevato in rapporto all'utenza personale.<sup id="cite_ref-RC50_6-0" class="reference"><a href="#cite_note-RC50-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> Col successore IBM 5150, meglio noto come l'IBM Personal Computer, si volle entrare nel mercato personal più generale, in tempi rapidi e con costi di sviluppo ridotti. Per questo si ricorse a un design provvisorio, poi rimasto definitivo, basato su un'architettura aperta e sull'utilizzo di componenti già liberamente disponibili sul mercato. Anche il <a href="/wiki/Sistema_operativo" title="Sistema operativo">sistema operativo</a>, il <a href="/wiki/PC_DOS" title="PC DOS">PC DOS</a>, per gli stessi motivi fu esternalizzato alla <a href="/wiki/Microsoft" title="Microsoft">Microsoft</a>, che poteva comunque venderlo a terzi come <a href="/wiki/MS-DOS" title="MS-DOS">MS-DOS</a>.<sup id="cite_ref-RC51_7-0" class="reference"><a href="#cite_note-RC51-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> Allo stesso modo il linguaggio di programmazione in dotazione era basato sul <a href="/wiki/Microsoft_BASIC" title="Microsoft BASIC">Microsoft BASIC</a>, già ampiamente diffuso. Il design della macchina non era molto originale, ma era comunque riconoscibile, e pur non essendo un trasportabile pesa poco più dell'IBM 5100.<sup id="cite_ref-RC52_8-0" class="reference"><a href="#cite_note-RC52-8"><span class="cite-bracket">[</span>8<span class="cite-bracket">]</span></a></sup> </p><p>La proposta di produrre un PC economico partì nel 1980 da William Lowe, direttore del laboratorio della IBM General Systems Division a <a href="/wiki/Boca_Raton" title="Boca Raton">Boca Raton</a>. L'<a href="/wiki/Amministratore_delegato" title="Amministratore delegato">amministratore delegato</a> di IBM, Frank Cary, gli concesse appena un mese per sviluppare un prototipo e un anno per portarlo sul mercato. Poco dopo, il progetto passò in mano a Don Estridge, con il nome in codice <i>Chess</i>. Data la natura insolita e affrettata del progetto, Estridge ottenne il permesso di condurlo in modo sperimentale, al di fuori delle procedure standard IBM. Bill Sydnes fu il responsabile dell'hardware, Jack Sams del software, Dave Bradley programmò l'interfaccia, Mark Dean e Dennis Moeller realizzarono il <a href="/wiki/Bus_(informatica)" title="Bus (informatica)">bus</a>, H.
