I found a version of BSD Unix recently and also the source code for the very first version of something that quite a few of us take for granted today, the web browser. Its safe to say that what you are using today is a decedent of the MOSAIC web browser in one way or another. As an experiment I will be trying to run this web browser with modern websites to see how they look and what kind of functionality they have with it. In theory I should get at least minimal functionality given that many early bits of the HTML or Hypertext Markup Language are still being used even today.
