Stumbled on this while scouting for images...
Claims to be how scientists at RAND in 1954 predicted home computers might look in the year 2004.
UPDATE: But it is (I'm informed in the comments below) a fake. Despite (pity!) I'll still leave the final question. See end of this post!
The text is a little hard to make out. It reads: "Scientists from RAND Corporation have created this model to illustrate how a "home computer" could look like in the year 2004. However the needed technology will not be economically feasible for the average home. Also the scientists readily admit that the computer will require not-yet invented technology to actually work. But 50 years from now scientific progress is expected t solve these problems. With teletype interface and the Fortran language, the computer will be easy to use."
Anyone fancy lashing up a model of the equivalent 50 years from now?
