A 1970s Audio Study Mate bundle created by Singer included a cassette player and a 35mm filmstrip viewer, as well as a microphone and some headphones, making it a multimedia offering for its time.
The filmstrip viewer was the more interesting part, as it included optics and a button that manually moved the image by one frame, or the tape could be set up to advance it automatically.
However, it never worked as it should have, and a teardown of the unit revealed bugs in the mechanism that was supposed to move the film, which were never fully fixed.
This led to comparisons with the difficulties of working with 35mm film, but also to praise for the ingenuity of the device, which, despite never working perfectly, was a pioneer in multimedia learning.
