The Master System was a video game console produced by Sega beginning in 1985.  For audio, the SMS used a clone of the Texas Instruments SN76489 chip.  These clones were also present in the Sega Genesis and Game Gear systems, the latter adding stereo functionality.

The SN76489 chip has 1 white noise and 3 square wave tone generators.  Each channel has 16 levels of volume.  The third square wave channel can also be used to control periodic noise in the white noise channel.
