In 1976, Magnavox released the Odyssey 400. It played the same games as the Odyssey 200 and used an additional Texas Instruments chip to display digital on-screen scoring (it was the first Odyssey system to display digital on-screen scoring).
On-screen scoring was quite well designed. As a matter of fact, the scores were large and were only shown when the ball was lost, and a large 'W' letter was displayed on the winner's side when the games were over. Like the Odyssey 100 and 200, the Odyssey 400 used the same three knobs to move the bats and control the "english" effect on the ball.
Basically, the Odyssey 400 is essentially an updated Odyssey 200 with mainly an addition of automatic serve and on-screen digital scoring.
