Information About

Mockingboard




The Mockingboard was available in various models for either the slot-based Apple II / Apple II Plus / Apple IIe systems or in one special model for the Apple IIc . Sound was generated through one or more AY-3-8910 or compatible sound chips, with one chip offering three square-wave synthesis channels. The boards could also be equipped with an optional speech chip (a Votrax SC-01 or compatible).

Some software products supported more than one Mockingboard. For instance, '' Ultima V '' supported two boards, for a total of 12 voices.

There was a Mockingboard-compatible sound card from Applied Engineering , called the Phasor . It had 4 sound chips and thus provided 12 audio channels.

In 2005, an Apple II Retrocomputing hardware company, GSE-Reactive , cloned the mockingboard and offers it for sale.
