Abstract
Abstract A conversion tool is disclosed herein for modifying a video cassette so that it will be accepted for playback by a special video recorder which includes a base plate with a pedestal in a critical corner location mounting a manually operated drill wherein the drill tip projects through the plate projecting from the undersurface thereof for a predetermined distance. The undersurface includes a plurality of guide posts depending therefrom against which a conventional video cassette is located in order to receive the drill tip. An identification hole is made in the cassette housing for subsequent sensing by mechanism in the video recorder.
