OS/2 and eComStation Last month, IBM made an announcement that put an end to any hope of an open source OS/2. Responding to requests from an online community that had previously collected 11,600 signatures in support of its cause, the company confirmed that they would not be releasing the source code of their OS/2 operating system. I used OS/2 as my main operating system for about four years, and unlike some former users, my reaction to the news sits somewhere between disinterest and relief.

The happy couple seperated i '87/'88 - which AFAIR was before IBM began developing OS/2 2.0 (OS/2 2.0 was partly 32-bit, the versions before was 16-bit) and OS/2 has seen heavy rewriting and optimizing in later generations like OS/2 Warp 3.0 (Enterprise) and OS/2 Warp 4.5 Server (Aurora).
The OS/2, and eCS, of today is based on the OS/2 Warp 4.5x Server - both client and server.

I hardly think that there is a great amount of MS code still to be found in OS/2 - also I hardly think that there are a great amount of IBM code to be found in Windows. W2K saw something like a rewrite for about 50mio lines of code.

With W2K Windows became the largest operating system on earth codewise - seing a few million lines of code doesn't make W2K an OS/2 clone.

Hmmm could it be the code for the Win16 subsystem ?

I didn't mean it as "a clone" but more like "relative" bastard children made outside the marriage.

And no, Os/2 3.0 is these days known as WinNT. But I'm pretty sure that there is a long, long, long way to Vista's level from WinNT 3.0

Wikipedia says following: - http://en.wikipedia.org/wiki/OS/2#Breakup
Microsoft started to work in parallel on a version of Windows which was more future-oriented and more portable. The hiring of Dave Cutler, former VMS architect, in 1988 created an immediate competition with the OS/2 team, as Cutler did not think much of the OS/2 technology and wanted to build on his work at Digital rather than creating a "DOS plus." His "NT OS/2," was a completely new architecture.

IBM grew concerned about the delays in development of OS/2 2.0 and the diversion of IBM funds earmarked for OS/2 development towards Windows. Initially, the companies agreed that IBM would take over maintenance of OS/2 1.0 and development of OS/2 2.0, while Microsoft would continue development of OS/2 3.0. In the end, Microsoft decided to recast NT OS/2 3.0 as Windows NT, leaving all future OS/2 development to IBM.

Windows NT's OS/2 heritage can be seen in its initial support for the HPFS filesystem, text mode OS/2 1.x applications, and OS/2 LAN Manager network support. Some early NT materials even included OS/2 copyright notices embedded in the software.


I don't say that it can be completely trusted but it tells something about the background of WinNT.

To me Windows has always seem to be prototype of an upcoming operating system. It's funny to notice that it is more than the truth here.
