"REV 1.34: Fixed race condition. Again. If Bill G. actually shipped this, users would hang daily. Good thing we have six more months of testing."
Furthermore, IBM still sells and AIX . Releasing OS/2 source code might create a liability if a competitor argues that certain kernel designs are "prior art" in a patent lawsuit. os 2 source code
In the early 1980s, IBM and Microsoft collaborated on a project to create a new operating system that would revolutionize the way people interacted with their computers. The result was OS/2, a powerful and feature-rich operating system that would go on to become one of the most influential and enduring platforms of its time. Today, the OS/2 source code remains a fascinating relic of a bygone era, offering a glimpse into the evolution of modern computing. "REV 1
The original 1985 JDA included non-disclosure stipulations that, while expired in some respects, still complicate the redistribution of "Joint Code". actually shipped this, users would hang daily
continued solo, developing OS/2 2.0 , the first true 32-bit version, and later the iconic OS/2 Warp . The "Black Box" of Modern OS/2
Scrolling through the code, you see two distinct handwriting styles. The early kernel code (the "Microsoft years") is tight, elegant, and obsessed with backward compatibility. The later IBM additions are robust, verbose, and enterprise-focused. You can almost see the schism forming in the comments—engineers arguing over APIs, memory models, and whether to prioritize DOS compatibility or true preemptive multitasking.
