sought-after ! Vintage Grand Prix Racing Handheld Game 1980s 1990s Works! READ DESCRIPTION

Vintage handheld grand Prix racing game. It has no manufacturing marks on it or date. It is in incredibly nice shape for the age cosmetically. The top has some discoloration and some minor knicks. I'm pretty sure it each works as it should but is not user friendly. The switch on the side turns the volume on and off. The volume is extremely loud! To turn the system on and off you have to hit the s3 button. The s2 button changes from game A to game B and a setup menu to set the clock. The right and left s4 and s5 buttons swerve the race car to avoid collisions as do the purple side to side buttons. The up and down buttons work because they can be used to set the clock but I cannot see any other function. I just wanted to describe operation because I had a hard time figuring it out! It is a very cool piece of video game history.
