    Default MS-DOS

    MS-DOS or the MicroSoft Disk Operating System is a series of Operating Systems produced by [wiki]Microsoft[/wiki] Corporation. MS-DOS was the initial product which was known for launching Microsoft to their current economic position. MS-DOS was the Operating System licensed with [wiki="IBM PC (5150)"]PC[/wiki] compatible computers, while the versions licensed by [wiki]IBM[/wiki] with their PC line was named PC-DOS.

    Comment: Actually MS DOS stands for Mighty Simple Disk Operating System, a product of the Seattle Computer Company. Bill Gates bought the rights so he could pitch an x86 operating system to IBM Boca Raton.

    I thought that Seattle Computer Products (SCP) initially called their product QDOS (Quick and Dirty Operating System) and then later 86-DOS.

    Basically, a "port" of CP/M 2.2 to the x86 world. Nothing at all like CP/M-86. It made sense from a business standpoint--you could convert most of your x80 assembly to 8086 automatically (even Intel had a product that ran on the MDS) and have a useful product in short order. Some early products (e.g. WordStar) did just that. And CP/M-80 had the lion's share of the base of personal computer application
    software at the time.

    DOS 1.x was a "flat" file system, just like CP/M (I don't think it implemented user areas), so it being FAT rather than CP/M style didn't bother most software applications.

    In public media anyway, the term "MS-DOS" didn't seem to appear until shortly AFTER the release of IBM PC-DOS 1.0, when Microsoft decided it would license versions to other third party OEMs.

    Quick DOS was a XTree type DOS file handler that I use(d) from Gazelle, which was the same outfit that marketed Back-It. It was commonly referred to as QDOS II or QDOS 3. Early 90's on those two.

    Yes, and that's the difference. The Seattle Computer Products QDOS was from the late 70's. By the 90's, it had been gone a long time.

    It's only been 5 years, so...

    Wouldn't that have been MS BASIC? Or, if "current position" eliminates that, then, surely Windows 95 or XP.

    Well, you can look at it several ways, but MS-DOS would have to be the product that "launched" MS into the big-boys club...
    It provided them with the capital to start Windows dev, along with the business division's products.

    95 & XP came after MS was already the leader in the SW biz. If you want a newer operating system to hang the laurel on, it would have to be Windows 3.1, which took off like a rocket!

    The licensing of MS-DOS took a few years to take hold by which time MS applications division was well established. MS BASIC provided with the IBM PC was what allowed MS to expand like crazy. In the longer term, MS-DOS was a veritable cash generator which is surprising considering how everyone involved hoped someone else would take the losses expected in providing an 808x operating system.
