CP/M : Le système qui regna sur la microinformatique, avant de disparaitre

Before Windows. Before MS-DOS. Before even the IBM PC… there was an operating system that almost no one remembers today—yet it dominated personal computing for nearly a decade. Its name: CP/M. And its history hides one of the most costly mistakes in the history of computing. In this video, we revisit the birth of CP/M in 1974, its meteoric rise to become a global standard, its technical architecture, and above all… how a single day of absence changed everything—and handed the industry to Microsoft on a silver platter. 🕹️ On the agenda: → The birth of CP/M (1974) and Gary Kildall → Why CP/M was everywhere in the 70s and 80s → How CP/M works: BIOS, BDOS, CCP → The IBM PC, QDOS, and the fall of Digital Research → The little-known legacy of CP/M in our modern PCs → CP/M in 2024: running it on ESP32 and Amstrad CPC! 🔔 Subscribe to Tech'Antik to dive into the crazy history of computing every week! #CPM #ComputerHistory #Retro #GaryKildall #MSDOS #Vintage #TechAntik #Microcomputing #IBM #Microsoft Thanks to our members and supporters.
