Summary

American personal computer company that created QDOS (Quick and Dirty Operating System) — which Microsoft purchased for $50,000, renamed MS-DOS, and licensed to IBM — making Seattle Computer Products the unknowing originator of the operating system that made Microsoft dominant.

Core Contribution

Created the operating system that Microsoft licensed to IBM and the entire PC industry — without understanding what they were selling — representing perhaps the most consequential underpriced technology transaction in history: $50,000 for what became the foundation of a trillion-dollar company.
