OS/2 Warp 3
OS/2 Warp 3 or OS/2 3.0 (or 'better DOS than DOS itself' according to IBM) was a version of IBM Operating System/2 produced in October 1994. With its 32-bit Windows NT-like mode as well as backward compatibility with DOS, earlier OS/2, and even Windows applications, it became quite popular for businesses however Windows NT continued to maintain a large part of the market share. It had its own web browser, called IBM WebExplorer and many applications were developed for it. While it normally used a standard x86 architecture, there was a version developed for PowerPC, which ended up a major failure.
