The Game Boy is the first product of the Nintendo Game Boy line. It was created by Gunpei Yokoi and Nintendo Research & Development 1—the same staff who had designed the Game & Watch series as well as several popular games for the Nintendo Entertainment System. It was released in 1989 and featured cartridges. It had 4 shade monochromatic graphics on a green screen.

Features Edit

The Game Boy has four operation buttons labeled "A", "B", "SELECT", and "START", as well as a directional pad. There is a volume control dial on the right side of the console and a similar knob to adjust the contrast on the left side. A sliding on-off switch and the slot for the Game Boy cartridges are located at the top of the Game Boy. Normally, users leave the cartridge in the system as recommended by Nintendo to prevent dust and dirt from entering the system.

The Game Boy also contains optional input and/or output connectors. On the left side of the system is an external power supply jack that allows users to use an external rechargeable battery pack or AC adapter (sold separately) instead of four AA batteries. The Game Boy requires 6V DC of at least 250mA.

A 3.5mm stereo headphone jack is located on the bottom side of the console which allows users to listen to the audio with headphones or speakers.

On the right side is a port that allows a user to connect to another Game Boy system via a link cable, provided both users are playing the same game. The port can also be used to connect a Game Boy Printer. The link cable was originally designed for players to play head-to-head two-player games such as in Tetris. However, game developer Satoshi Tajiri would later use the link cable technology as a method of communication and networking in the popular Pokémon video game series.
