  Miert az x86 lett a PC alapja: David Bradley, az eredeti PC BIOS-anak iroja es a Ctrl+Alt+Del kitalaloja irta 1990-ben a Byte-ban:
  Why the 8088?

  There were a number of reasons why we chose the Intel 8088 as the IBM PC's central processor.

  1. The 64K-byte address limit had to be overcome. This requirement meant that we had to use a 16-bit microprocessor.

  2. The processor and its peripherals had to be available immediately. There was no time for new LSI chip development, and manufacturing lead times meant that quantities had to be available right away.

  3. We couldn't afford a long learning period; we had to use technology we were familiar with. And we needed a rich set of support chips—we wanted a system with a DMA controller, an interrupt controller, timers, and parallel ports.

  4. There had to be both an operating system and applications software available for the processor.
