Y Combinator's Xerox Alto: restoring the legendary 1970s GUI computer (http://www.righto.com/2016/06/y-combinators-xerox-alto-restoring.html)
Hey i work for Xerox... ;D
yeah, the machine which inspired so many stuffs 10 years later.
some say it was a fancy project because Xerox had so much money they could make fancy futuristic things like that.
A bit like the concept cars for car manufacturers.
Is there even a Xerox Alto emulator somewhere ? can there be demos and game on those ?

Of course there is an emulator, tried it years ago!
