The Mockingboard (a pun on "Mockingbird") is a sound card built by Sweet Micro Systems for the Apple II microcomputers.
In 1981, Sweet Micro Systems began designing products not only for creating music, but speech and general sound effects as well,[1] culminating in the release of the Mockingboard in 1983.
[2] The Mockingboard's hardware allowed programmers to create complex, high-quality sound without need for constant CPU attention.
An IBM PC-compatible version was developed, but was only distributed with Bank Street Music Writer.
