From Boing Boing, a link to edsac.net, a site dedicated to the first stored-program computer to operate a regular computing service. It was constructed in 1949 at Cambridge University. Apparently, in 1952 someone by the name of A. Douglas wrote a version of Tic-Tac-Toe for it (I didn’t see the code anywhere, but I’m in a rush this morning) back in 1952. Neat! Edsac.net has a nice emulator, which includes a telephone dial! Apparently, to place your X or O, you simply dialed the corresponding number.
