Looking for old computer book

Paul wrote.... To which Mike replied... It may well be the one that Paul saw and was asking about. But just as another datapoint, I too remember as a kid seeing a design for a computer that used a telephone dial for input and it was not the same one as pictured in the ebay article that Mike pointed out. The one I saw was more "horizontal" in appearance with the dial on top, whereas the one on the ebay auction is more "vertical" and has the dial on the front. I also remember that the one I had seen definitely had a lot more components. An off-topic side-note: I can not recall what media I saw this in. It could have been a radio-electronics magazine, an old book from the local library (as a kid I spent several hours every day in the library soaking up books on various interests), or it may have been in the worldbook (I think that was the name) encyclopedias. I had a set of regular encyclopedias that also had science projects for many major subjects. These werent usually trivial experients, they were things that would be suitable for presenting in a school science fair for judging. I distinctly remember two of the projects. One was on the working of the heart. It was a board that tilted front to back on a triangular wedge. Routed into the board was a logical diagram of the human heart. The valves were one way metal flaps that opened by rotating on a thin metal shaft or wire. The blood was a set of marbles. When you tilted the board to the back, the marbles rolled through the valves in one direction, then when you tilted it back the other way the flaps only let the marbles go into the correct chambers. There was also a project showing air pressure... it was basically two sealed mason jars, each half full of water. There was a common pipe between them, then each one had a separate pipe just going out the top not connected to anything. One of the open pipes you put a balloon on. When you moved one jar higher than the other the balloon would inflate. Anyways, I wonder if the telephone dial computer project I saw was in the same encyclopedia set. Jay
