The AdLib soundcard was released in 1987 and featured the Yamaha YM3812 sound chip (also known as the OPL2). The card supported 9 channels of 2-operator FM synthesis. By 1992 the Sound Blaster card had wiped the AdLib off the market by copying it's features, adding digital sound and a gameport. The AdLib is the godfather of music in PC games.
