Item for sale is an extremely rare Game Boy Display Station for stores to demo the original Game Boy during its release years. The Display Station plays Tetris and displays it (as pictured) on the large screen as well as on the Game Boy itself. The sound comes out strongly from the working speakers built into the station. The Tetris game, including all buttons, work great without any set time interruption/undesired resetting. There is a red "reset" button. There is no on/off switch. As soon as the 3-prong (standard) plug is plugged in, the Display Station turns on.
The screen quality is great, considering how old this unit is.
I have not had the unit on for over two hours in order to preserve the life of this historic piece.
The screen quality looks better than the pictures can capture. The figures are not as fuzzy as Picture 2 represents. That "bright line" or "discoloration" that you may be able to see in Picture 2 appears there because of the effect of taking a screenshot with a camera.
Since I don't have the key to open the lock (pictured) I cannot interchange the games. Even with the key I'm not sure if you can interchange the games. But I'm pretty sure that if you can operate a screwdriver you can change out the games, assuming that you have a key made by a locksmith. Using an allen wrench, I unscrewed the unit from the stand to show that unit can be picked up in a normal size car.
