A german site, but still great. Here are some features of their site you should check out. Compare to the other, known German site spymac.com, the stuff this page shows is for real
The prototypes. Check them out, they are great and REAL!!!
Newsweek: What you are searching for, the 16 page commercial from 1984
Confidential: All known Apple Easter eggs AND stuff Apple invented but never released...(not prototypes, stuff that was invented to be sold but didn't sell well)
Modelle: The Tech specs of ALL ever released Apple computers, in German though, but I think it is not hard to figure it out.
Hope you find what you are searching for. At the moment, the page loads very slow, maybe they are updating it or something, but check it out, it's a great site!
btw: I know that it is illegal, but could anyone who would be willing to share a version of the work-in-progress X86 Rapsody contact me? Thanx!
