Video Image Overlay Prototype


One wooden board with electronic components attached atop it. The components are in three parts: a flat circuit board with black connectors, a tall circuit board with a black shield, and an on and off switch. There is a brown power cord and a light green connector, presumably to connect to the camera component (not included in this accession). There's some writing on tapes: "Video Cam", "Monitor", "Y/G" and others on the tall power supply and the black connectors are numbered. The board was one part of the device along with a camera connection (not received). The concept was patented under U.S. patent 4710873A although the patent was not officially credited to Ralph Baer, something he sought to rectify in 1995.
