1988 video bowling machine. Loooks good and works great. Asking $350.
The lane is displayed vertically with the score information of the left of the lane. There are left and right hook buttons which can be used to determine the amount of spin that will be put on the ball. Once the desired amount of spin has been set the player moves the trackball to the left or right to determine the starting location of the throw. Once the player has the starting position in the right spot the trackball is rolled upwards towards the screen to throw the ball.
The game can be played with up to 4 players in hot seat style turns.
