IBM PC Day and Enjoy!

IBM PC Day - 1981: IBM introduced the 5150 personal computer. It swept away the competition and effectively had the field to itself.

For an operating system, IBM first went to Digital Research, which had developed CP/M. When Digital Research declined, IBM went to a small firm known for microcomputer adaptations of Basic: Microsoft.

Microsoft bought the rights to Seattle Computer Products' QDOS. QDOS became PC-DOS and later MS-DOS.

Before 1980, IBM made only mini and mainframe computers. The old-line firm was not sure that the fledgling microcomputer market would be at all profitable.

But once the company decided to act, it developed the 5150 in less than a year at its Boca Raton, Florida, facility. IBM selected Intel's 8-to-16-bit 8088 processor.
