Additional Videos for your historical watching pleasure
The Computer Chronicals was a computer show broadcast from 1983 - 2002. It has some great historical shows (from the actual times) showcasing various peices of computer hardware. Quite entertaining to watch now, but also a great place to learn why certain machines (especially the Amiga) were so revolutionary in their day - which any oldskool scener will be able to tell you! Enjoy.
Amiga vs. Atari 1985 - Ahhh... the Bouncing Ball Demo, Deluxe Paint + more.
The New Amiga 1987 - Amiga 2000 and the Amiga 500. Video Toaster, MIDI + more.
The Amiga 3000 1990 - Amiga 3000, Amiga 2500, inc. first release of Lightwave 3D
Computer Graphics 1984 - Great 3D technical demos from Sillicon Gfx. A record breaking fill-rate on an Apple IIe (watch it go! Oh the power). I'm certain shows like these helped inspire a generation to code their own demos and cracktros.
