Denoted by model number DMG-01 (which stands for Dot Matrix Game), the Game Boy can be powered by either four AA batteries or an AC power adapter, the latter of which has unsurprisingly disappeared into the clutter abyss.

Despite the one model number, the Game Boy came in a handful of different models over the years, with subtle differences to the circuitry.

If you're wondering, that 800 number does still call Nintendo's support line, just in case you ever need some help with your retro handheld.
