Car Cell phone in the 1970s

The silicon chip, unnoticed by most of us a few years ago, is now something everybody has heard about, few understand and many are beginning to fear. Is it really the basis for a revolution as profound as the industrial revolution? Bernard Falk takes a layman's view of what the silicon chip is, how it's made and works. From a Chicago millionaire's home to a Birmingham car-test track, and from a psychiatric hospital in Scotland to a Swedish factory, he looks at how the new technology is being used and what it could do in the future.
