The America's Smithsonian exhibit opened this month at the Los Angeles Convention Center - the first stop in a two year tour of the United States. There are lot's of interesting displays including both Gemini and Mercury space capsules, Lincoln's hat, and so forth. But perhaps most interesting is the equipment used for the individually guided tours. Typically, museums use tape recorders which one can rent and then follow a prescribed path to learn all the specifics of the exhibits. They adopted a Newton message pad to deliver the audio message.
Every exhibit is numbered.
When you arrive at the exhibit, you press its number into the large keypad pictured on the face of the Newton - the appropriate explanation is played back through earphones.
