This three part documentary covers the lifetime and story of the man who was robbed from being Bill Gates, Gary Kildall. This documentary is sponsored by https://www.PCBWay.com! Dive into the untold story of Gary Kildall, the overlooked genius who laid the foundation stones of the personal computing revolution with his groundbreaking CP/M operating system. In this eye-opening exposé, we unravel the momentous journey of a tech maestro who could have been in the limelight, akin to Bill Gates, but was tragically edged out by the fierce market strategies of Microsoft and IBM. Uncover the dramatic twists and the bitter rivalry that ensued as MS-DOS controversially eclipsed CP/M, bringing a sad and abrupt halt to Kildall's soaring career. Watch as we shed light on a saga brimming with innovation, rivalry, and heartbreak, echoing the turbulent early days of the software industry. Don't miss this deep dive into the life of a visionary who should have been etched in history as a titan of the tech world - Gary Kildall: the man who should have been Bill Gates. #GaryKildall #CPM #DigitalResearch #TechHistory #UntoldStories Don't forget to LIKE this video and please SUBSCRIBE to my channel!
