When it comes to networking computers, Windows Server has become the gold standard. Some recent analysis rejects this claim.Share on Facebook Share on Twitter Pinterest Email Kildall claimed that QDOS used parts of CP/M to speed development, that ironically Microsoft's market dominance was originally based on an act of the "piracy" that the company now so vocally abhors. Microsoft had been a major player in programming languages for 8-bit systems, but had never developed an OS they bought QDOS and turned it into MS-DOS. When that was late, they did their own QDOS, Quick and Dirty Operating System, in a few weeks just to give customers something while they waited for CP/M. Naturally, they promised customers CP/M-86, the obvious OS for such systems. Seattle Computer were a hardware vendor with a CPU board based on the Intel 8086 using the S-100 bus. One story that became widespread was that CP/M-86 missed out on the IBM contract because Digital Research founder Gary Kidall missed a meeting because he did not come in from his yacht.

CP/M-86 was (like many or even most large software projects) late and initially buggy opinions on the details differ widely. There were other reasons, some complex controversies, and a range of rumours. One reason it won was that it had better license terms IBM offered PC-DOS free on some systems and clone makers offered MS-DOS free. Most expected those two to dominate the market in 16-bit systems DOS was initially clearly the dark horse.

CP/M had been the standard for 8-bit machines used in business and the P-system, a Pascal-based portable virtual machine, was fairly widespread in education and was used on the Apple II.

In fact, IBM offered three OSs for the original PC - PC-DOS, CP/M-86 and the USCD P-system. CP/M was the most common third party command-line operating system available to that time, and served as the operating system for the previous generation of computers (such as some IMSAI machines)

IBM's "great folly" with DOS was the assumption that "people pay for the hardware no one makes money on software." IBM chose Microsoft over Gary Kildall's Digital Research Inc., the company which produced CP/M. It can be said with a degree of certainty that the original deal Microsoft made with IBM, where MS-DOS was licensed to run on IBM's computers instead of sold outright to them, was the chief enabling factor in Microsoft's rise to its current status as the largest software vendor in the world. The original IBM PC first booted to its BIOS, and then the BIOS booted the first 512k sector of disk, which contained the DOS Master Boot Record.ĭOS applications Windows on top of DOS DOS catapults Microsoft to the limelight The DOS command line interface came to define the stereotypical " hacker typing away on a keyboard" method of using computers in the 1980s. It used a command line interface because affordable IBM PC-based home computers of that era were not capable of running a Graphical User Interface yet. MS-DOS is Microsoft's command line Disk Operating System, originally bought and modified to run on the original IBM PC.
