It’s 1974, and a young programmer named Paul Allen has just caught a glimpse of the world’s first personal computer, the Altair 8800. It has the potential to change the computing landscape forever — but it doesn’t yet have an operating system. Altair’s developers sank every dollar they had into its hardware, banking that someone else would figure out how to make their machine run.Now programmers are racing to develop an operating system and deliver it to the company’s headquarters in New Mexico. Allen knows he can do it, but in order to do it first, he’ll need some help. For that, he reaches out to his childhood friend, a 19-year-old Harvard sophomore named Bill Gates.Support us by supporting our sponsors!Fin - Go to Fin.com/BW to try Fin for free.Squarespace - Create your beautiful new website at Squarespace.com/BW and use offer code BW at checkout.
