Microsoft and Computer History Museum : Source Code for MS Dos1.1 & 2.0 and Word for Windows Version 1.1A released

Few days back Microsoft released the source code for MS Dos1.1 and 2.0 and also Microsoft Microsoft Word for Windows Version 1.1a. This release was made for the public all over the world on the official ComputerHistory website.

Tim Paterson who wrote 86-DOS 1.10 was hired by Microsoft in May 1981, released PC DOS version 1.0, which supported only floppy disks, was shipped when IBM first released their PC in August 1981 after the collaboration of Microsoft and IBM in 1980. Microsoft then substantially rewrote the software to support subdirectories and hard disks in order to do that version 2.0 was released with the IBM PC-XT in March of 1983 which after receiving all the rights and licenses named as MS Dos.

Also no statement has been released on the question arising that "What took company so long to release these Source Code?"

Microsoft Word

One of the first programs was BRAVO, created in 1974 by Butler Lampson, Charles Simonyi and others at Xerox PARC, the Palo Alto Research Center, for the groundbreaking Alto computer. Simonyi later said,

 ”It was clear that quite a beautiful editor could be written for the Alto. Remember, the Alto had a black and white bitmap display. It had a mouse. It had an un-decoded keyboard. It had all the ingredients that are necessary for WYSIWYG. And, of course, then the network came around. The laser printer was coming alive. So all the components were there, except for the software…. We set out to write an editor and we finished it about three months.”
