This talk was recorded and lost in the depths of the University's Computer Science Club's office until its recent rediscovery. We digitalized it for your enjoyment. In this talk, Bill discusses his role as a developer in the early days of Microsoft, and his views on the future of Microsoft. He even touches on the now famous 640K."
