The choices made during the design and development of the IBM PC were fundamental to both its success and the broader future of computing. The selection of Intel’s 8088 microprocessor was a pivotal decision, heavily influenced by financial and efficiency considerations. While there were other competitive options, the 8088 microprocessor’s choice inadvertently cemented the x86 architecture as the cornerstone of modern processors. This decision not only standardized the hardware but also laid the groundwork for future technological developments. In addition to this, IBM ensured multiple manufacturing sources for the processor to prevent any potential supply chain issues, leading Intel to license x86 technology to AMD, which later became a significant player in the industry.
On the software front, IBM initially intended to use CP/M, a popular operating system developed by Gary Kildall. However, logistical challenges and cost concerns led IBM to approach Microsoft for an alternative solution. Microsoft brokered a deal to use SCP’s Quick and Dirty Operating System (QDOS), which was subsequently adapted by Tim Paterson to meet IBM’s specific requirements. Microsoft eventually acquired QDOS for $50,000, retaining critical rights to the operating system. This move allowed Microsoft to license its MS-DOS to other manufacturers, thus fueling an expansive ecosystem of IBM-compatible PCs. The IBM PC’s open architecture encouraged third-party hardware and software development, which in turn fostered innovation and competition, shaping the future of personal computing.
