Appreciate more the story, read the previous post:
Even though the Softcard was a slight diversion from Microsoft’s normal focus on computer language software, Gates embraced it because it represented yet another strategic opportunity to extend CP/M’s market domination while also binding Microsoft BASIC to CP/M. Microsoft eventually sold hundreds of thousands of Softcards, which told Sams that it was a popular and reliable product.
Sams started his software hunt by contacting Gates and proposing IBM license the Softcard, along with all other programming languages Microsoft offered.
What Sams didn’t understand was that although Softcard was a Microsoft product, its most valuable feature was the CP/M operating system, owned by Digital Research. Gates told Sams that IBM needed to license CP/M directly from Kildall and offered to help Sams make the deal happen.
