30 years ago, Steve Jobs and Apple unveiled the Macintosh. Most people have seen that video, but I bet most haven’t seen the one he filmed eight years later, demoing the latest version of his new operating system, NeXTSTEP3.0.

Fascinating to see the Mac heritage in NeXTSTEP carry through the acquisition and transformation into OS X. It’s hard to remember, but in 1992 Microsoft had just released Windows 3.1 – NeXT was light-years ahead of Microsoft.
