Today's IT world is dominated by Windows, Linux, Mac OS X, Android and a handful of other operating systems - but what about in years gone by? We look back at five operating systems that enjoyed their own (often brief) limelight before fading away.

Then, in 1990, along came Windows 3.0 and, despite generally being considered a poor relative, it killed off OS/2 within a couple of years. The rest is history.
