Apple IIGS

The Apple IIGS, the fifth and most powerful model in the Apple II series of personal computers produced by Apple Computer. The "GS" in the name stands for Graphics and Sound, referring to its enhanced graphics and sound capabilities, both of which greatly surpassed previous models of the line. At the time of its release, while it featured graphics comparable to other advanced home computers of the era (even more advanced than the black and white Macintosh, apart from a lower vertical resolution), it was most notable for its then state-of-the-art sound and music synthesis which surpassed all other personal computers at the time.
