Did you know that Microsoft made their own version of UNIX, all the way back as far as 1979, before MS-DOS and Windows was even a thing!? As usual, no story of computing folklore would be complete without a bit of controversy, and the story of Xenix is not short of a fair few crazy moments! Controversy aside, I bet you'll learn a good bit about a bit of history today, that could have changed the way we see and use computers a whole lot, if Xenix had won the day. Get ready for a compelling story! Learn about: Legal battles! Product mergers! Acquisitions! UNIX on the original PC and Apple Lisa! Steve Ballmer on Cocaine!
