  1. Sega used real SN76489AN chips in their SG-1000 game console and SC-3000 computer, but used SN76489A clones in their Master System, Game Gear, and Mega Drive/Sega Genesis game consoles. These modified sound chips were incorporated into the system’s video display processor. Although basic functionality is almost identical to that of the original SN76489A sound processor, a few small differences existed: the randomness for the noise channel is generated differently, and the Game Gear’s version includes an extension for stereo audio output. The periodic noise is also 16 stages long on the Sega-made clones; this makes a significant difference for music/programs which use periodic noise, as sounds will play at 6.25% lower pitch than on the TI-made chips.
