Walk-Through Computer

The giant exhibit featured an authentic-looking, two-story working model of a desktop computer enlarged to 50 times its normal size. The purpose of the exhibit was to show the anatomy of a computer and to explain how the various parts worked and communicated with each other.

The Walk-Through Computer ran a program called "World Traveler" Ė a route-finding application. Using a giant (9'x6'6"x5') trackball to point, they could choose starting and destination points from among more than 300 major world cities. The computer found the shortest land route between them, and offered a slide show on the giant monitor of sights they would see along the way.

Walking inside the computer, visitors saw how the computer performed its route-finding task. Pulsing lights simulated the flow of data between the internal components and peripherals. Visitors walked past a ceiling-high video-processing printed circuit board to view the microprocessor. Looking down through one of the many viewports, they inspected the chipís circuits magnified 500 times. They also saw microelectronic circuits in action on banks of random access memory chips, and peered into a giant spinning disk drive retrieving data. An entertaining video in the Software Theater introduced software concepts, supplemented by interactive "learning stations," on computer architecture and programming.

The Walk-Through Computer captured the imagination of media around the world from the TODAY show, ABC Evening News, CNN, TV networks in Germany, Japan, and Australia, as well as the AP, UPI, The London Times, Der Spiegel, The New York Times, and Newsweek. It also led to a major surge in Museum attendance.
