The Lost 1984 Mac Video

An anonymous reader writes "Never seen video footage of the introduction of the Macintosh in January 1984 was published for the first time on the Internet today. Renowned Mac user Scott Knaster kept that Betamax video tape for 21 years, and German media agency TextLab has unearthed this only surviving video tape of the launch." They could probably use more mirrors for the 22MB movie.
