Close but no cigar! 1) IBM did in fact offer CP/M as an alternative operating system 6 months after the initial offering of the PC. It did not sell well because it cost 6 times the $40.00 charged for PC-DOS.Yes he did sell it...IBM paid for most of the development of PCDOS but allowed Gates to also market the program under the name MSDOS. Bad decision on IBM's part. IBM also saved intel's bacon by buying 20% of the company and pumping in a lot of money then selling out after Intel was on firm footing.When Bill Gates sold his DOS program to IBM he really didn't sell it, He gave it away so every PC will be capable of running Microsoft programs. Now we are for the sake of clarification, Nickel and Dime hobbyist. P&C will go after those that commissioned these blade holders, ie. PSI, Craft Supplys... before they come at us. NOW as others have said, they rather have someone buy their blades than **** and moan over what we make.
Let's get this all straight. IBM approached Bill Gates about an operating system for their computer. He referred them to Digital Research who had CP/M available but the owners wife would not sign the NDA so IBM went back to Gates. Bill Gates actually didn't have anything do went and purchased QDOS from Tim Paterson of Seattle Computer Products keeping his negotiations with IBM secret so walked away with it for $50,000. He then negotiated the deal with IBM to license the operating system but talked them into letting him keep the rights to offer it elsewhere. The rest is history.

2) It was an internal decision to go with an outside developer for PC-DOS because IBM had lost a series of copyright infringement lawsuits where they had looked at products, then developed their own. It was always IBM's plan for Microsoft to own PC-DOS. Bill Gates did not out-smart IBM as has often been implied. That decision was perfectly in keeping with IBM's original marketing plan for the PC where IBM made the interface specifications immediately available for other developers to use.
3) Microsoft was not contacted until July 1980 and the contract was signed in November 1980 first shipments were in February 1981. Microsoft did buy their version of DOS from Seattle Computer Products and modified it to meet IBM Specifications. Going back to Holz Machaniker's post...Since originally IBM quickly had 85% of the PC market and IBM was selling PC-DOS and MS-DOS was microsoft's bread and butter, they weren't giving it away. They did give away software to displace Netscape as the dominant browser software.
1) IBM did in fact offer CP/M "AFTER" the fact but in the run up had passed on it. AS you said it was way more expensive.
2) Outsmarting IBM, not really implied, but in hindsight, where the market went it was not good for IBM in the long run. BUt who could have seen the future in November 1980....oh yeah, Steve Jobs did :biggrin:
3) PC-DOS and MS-DOS were "licensed" not sold.
Ultimately, everything I stated lines up perfectly with the history. I decided to skip using 10 pages for all the details. My main "correction", it was licensed and not sold.
