Editing 86-DOS (section)

===IBM interest===
In October 1980, [[IBM]] was developing what would become the original [[IBM Personal Computer]]. CP/M was by far the most popular operating system in use at the time, and IBM felt that it needed CP/M in order to compete. IBM's representatives visited Digital Research and discussed [[licensing]] with Digital Research's licensing representative, [[Dorothy Kildall]] (née McEwen), who hesitated to sign IBM's [[non-disclosure agreement]]. Although the NDA was later accepted, Digital Research would not accept IBM's proposal of {{currency|amount=250,000|code=USD|linked=no}} in exchange for as many copies as IBM could sell, insisting on the usual [[Royalties|royalty]]-based plan.<ref name="Freiberger_1984_Fire_Valley"/> In later discussions between IBM and [[Bill Gates]], Gates mentioned the existence of 86-DOS, and IBM representative Jack Sams told him to get a license for it.{{citation needed|date=July 2011}}
