Microsoft is working with the Computer History Museum and made ??decision that previous programmers never thought of before, Releasing the MS-DOS operating system and Word for Windows applications. Both can be downloaded for free on the Computer History Museum’s site.
The source code of MS DOS 1.1 and 2.0 are available in the Computer History Museum website and can be downloaded for free. Meanwhile , Both MS DOS 1.1, 2.0 and Microsoft Word for Windows 1.1a is published by a non-commercial license, which prohibits users re-publish it on the internet .
Roy Levin, a programmer at Microsoft and Director of Microsoft Research, said Microsoft’s move to publicize the MS – ??DOS and Word for Windows is to show the world that great things start
from small things .
“It’s mind-boggling to think of the growth from those days when Microsoft had under 100 employees and a Microsoft product (MS-DOS) had less than 300KB (yes, kilobytes) of source code
“Levin said as quoted by PC World , Tuesday(March 25, 2014) .
“From those roots we’ve grown in a few short decades to become a company that has sold more than 200 million licenses of Windows 8 and has over 1 billion people using Microsoft Office.” he added .
Levin also said that the next great product of Microsoft could be in the form of something small and trivial, such as MS-DOS and Word for Windows.
“Thanks to the Computer History Museum, these important pieces of source code will be preserved and made available to the community for historical and technical scholarship,” Levin added.
The history of MS-DOS can not be separated from the IBM PC. At that time (1980), Microsoft’s use the OS that purchased from Seattle Computer Products as a material to make its own OS, PC-DOS.
PC-DOS version 1.0 is released at the same period as IBM launched its first PC in August 1981. Meanwhile, the 2.0 version was released in at the same time with the IBM PC-XT in March 1983. After that, Microsoft later licensed the OS to OEMs under the name MS-DOS.
As for Microsoft Word for Windows, Which was released in 1989, Is actually a renewal of Word for DOS which began shipping in 1983.
