While a little bit technical (you can generally skip those parts if necessary) the article above on the Cray-1 is fascinating. Computer development has advanced exponentially since 1976, but you can't really compare this computer with current ones, due to the different functions they were meant to fulfill. At any rate, an interesting bit of computer history...
