The Mockingboard (a portmanteau between mockingbird and motherboard) is a sound card built by Sweet Micro Systems for the Apple II microcomputers. It provides multiple channels of sound synthesis using one or more AY-3-8910-style sound chips, and some models also offer speech synthesis using Votrax-style speech chips. It improves on the Apple II's limited sound capabilities, as did other Apple II sound cards. Mockingboard cards are supported by many Apple II software products.
