A look at new developments in information technology. American reporter Freff risks using a computer database before buying a painting in a New York antique shop. Fred Harris explains how the home micro can be used to communicate with other computers down the telephone line. Ian McNaught-Davis takes a trip down memory lane to explain the way that computer storage devices have developed over the years. And, looking forward, Freff visits an American research team who are developing 'super memories' that use lasers to read and write data onto protein molecules.
