The Philips SAA1099 sound generator was a 6-voice sound chip used by some 1980's devices, notably:
- The SAM Coupé British-made computer
- The Creative Music System (C/MS) by Creative Labs, which was also marketed at RadioShack as the Game Blaster. They had 2 chips, for 12 voices.
- Their Sound Blaster 1.0 cards (and 1.5 if you added it on). However that card also had an OPL2 chip (aka YM3812), which became much more popular.
The chip produced square waves and noise (at 3 different frequencies). Its main feature was that it could output in stereo (it was possible to set the left and right channel volume independently).
