I've seen the demonstration and I go there all the time. I LOVE computer history, it's our legacy, we're standing on the shoulders of the real pioneers. Those people who had to start from punch cards and mainframe terminals... they're the ones who really knew how to program.
What's crazy is it's so unknown to the general populace. Kids learn about George Washington and Bill Gates the businessman who gave us Windows, but they have no clue who Ken and Dennis are. Punch cards are meaningless to them. They wouldn't know an old hard disk from a vinyl record box. But one day they will. One day people will realize that this was the beginning of humanity. The real beginning. The PDP-11, the 1400 series, the ENIAC.
If you haven't been to the computer history museum, go!
