Tape-slide set (1960s – 1980s)

Tape-slide sets usually consist of a set of 35mm slides with accompanying audio on Compact Cassette. These were most often used for education and training purposes, but have also been used for tourism and art.

Later slide projectors could be automatically advanced by an inaudible tone on the tape, but often the presenter would hear an audible tone and have to advance to the next slide manually. On some tapes, one side would have audible tones for the older projectors, and the other side would have the subaudible tones for automatic projectors, while others combined both types on the same side.

At a time when tape players and slide projector were common, they were a relatively inexpensive way to produce educational materials, and could be viewed by a large group. Self-contained units such as the Kodak Caramate were available for instances where a small number of people wanted to view a presentation, and these included a slide projector, a cassette player, and a built-in screen.
