Abstract
A microfilm display device is responsive to a film address signal and controlled by a microprocessor to locate a desired film and select a film image for display on a cathode-ray terminal. The film image is converted to a video signal for display on the terminal. The video signal is used for fine positioning of the raster on a flying spot scanner which illuminates the film.
