IBM snubs OS/2 open source plea
 

IBM has dashed the hopes of a bunch of software nostalgics by refusing to open source its coulda, woulda, shoulda OS/2 platform. Online OS/2 community OS/2 World.com first petitioned IBM to throw open the OS back in 2005, when the firm stopped selling the product. It gained just over 11,600 signatories. It followed up last November, with a letter reminding the firm that there were still OS/2 diehards out there who wanted to continue using the operating system for legacy applications (and presumably playing chess).
