The Apple Macintosh was introduced to the public at the Boston Computer Society on January 30, 1984, but the film was nearly lost to history. No digitized versions of the film existed until January 2014, and much of the footage existed only on U-matic cassettes. Thanks to the hard work and investment of BCS co-founder Jonathan Rotenberg, videographer Glenn Koenig, Software Arts co-founder Dan Bricklin and the Computer History Museum, a vintage recording was recovered and made available to the public on the event's 30-year anniversary.

This BCS presentation was a precursor to the huge media events we're accustomed to now and, being in 1984, preceded by more than a decade the 1998 iMac introduction event commonly cited as "the first Stevenote." For the first time, the entire Apple Computer crew demonstrated easy-to-use home computing programs such as MacWrite; discussed innovative developments such as dot matrix printing(!), which allowed users to print images at home for the first time; and extolled the virtues of point and click, copy and paste, and easy image manipulation. One notable selling point early in the video touts the portability of the 3.5-inch floppy, which could fit 400k of storage "right into your shirt pocket." There are also great moments in Apple advertising history here, as many of the early-'80s commercials are included in the presentation.

The version of the film below is edited to remove dead space (and to include clearer images of slides and projected video), but is still fairly lengthy at an hour and a half. If you're interested in tech history at all, it's well worth the watch. And if you're interested in the preservation project itself, there are details on Bricklin's website, in Rotenberg's announcement at the Computer History Museum, and in Harry McCracken's post at TIME.
