A portable battery operated TV set project on Product 3 / Prof. Youngkin's class in 1976 at ACCD. Main concept was a separation a picture tube including speaker and knobs from heavy the battery pack on chassis, so that it can be smaller and lighter to lend itself to any place easily.
This idea have been blessed by Mr. Oniki, president of Sony Amrica at that time, when I have presented my intention to him first. Then he helped me to get all mechanical components to design. Thanked for his corporations at that time.
