• Today in History - 1981

    They went to Microsoft for the operating system (QDOS, renamed PC-DOS
    and later sold by Microsoft as MS-DOS) and to Intel +< for its 8088 processor. They chose an existing monitor from IBM Japan and a
    dot-matrix printer by Epson. Only the keyboard and the system unit
    itself were new designs from IBM. Even more shocking at the time, the
    team opted to make the IBM PC an "open architecture" product, and
    published a technical reference of the systemgCOs circuit designs and software source codes. With this information, other companies could
    develop software and build peripheral components.

    It is even more shocking in hindsight considering that they would later try
    to make it more difficult to use non-IBM parts on their machines.

    Well, the guys who wrote the manuals and sneaked them past the bean
    counters weren't the management pirates who woke up and realised that
    they might lose a few pfennigs to the cloners. Sorta like Slick Willie
    Gates gritting his teeth when some bright sparks cloned MS-DOS.
