Haha. Bill Gates var klog nok til at vide at man ikke bare lige selv udvikler sådan noget fra bunden, så han købte det OS for en billig penge af en mindre virksomhed i Seattle. De fattede jo ikke lige at IBM skulle bruge et OS til tusindevis af PC''ere
"By 1980, IBM had decided to build personal computers and needed a PC operating system. (Computers are born naked; they need operating systems to be presentable.) Mammoth, blue-chip IBM employed thousands of capable software builders, and didn''t trust a single one of them; IBM hired Microsoft to build its operating system. Microsoft bought Q-DOS from a company called Seattle Computer Products and retailored it for the PC."
