Many years before VCRs and DVRs, my brother and I recorded lots of audio from old TV shows. One of our old audio tapes has a snippet from Walter Cronkite's science TV show Universe. In this episode, Walter learns about computer effects and is turned into a program just like Tron. For years I wished this would show up on DVD or YouTube. My wish was granted when I found it on YouTube last year.
