The Commodore Billboard is a nice site with a extensive collection of Commodore adverts, brochures and TV commercials from the 80ies. Vintage Fun!.
My recommendation: a TV spot comparing the C64 to the Apple II (MPEG-1).

Yeah! a cool site, I have found it browsing youtube and seeing the reference to the site.
the apple thing commercial is cool, did they compare the amiga to some other computer in US ? I guess the Atari ST..
