The Mockingboard (a pun on "Mockingbird") is a sound card built by Sweet Micro Systems for the Apple II microcomputers. It improves on the Apple II's limited sound capabilities, as did other Apple II sound cards.

Contents

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 Sound II was introduced at US$199(equivalent to $610 in 2023), and the Sound/Speech I at US$299(equivalent to $910 in 2023). [2] The Mockingboard's hardware allowed programmers to create complex, high-quality sound without need for constant CPU attention. The Mockingboard could be connected to the Apple's built-in speaker or to external speakers. However, as the quality of the built-in speaker was not high, the instruction manual recommended obtaining external speakers.

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 chips such as the Arctic-02, SSI 263P, SSI 263AP or 78A263A-P [3] [4] ).

Some software products supported more than one Mockingboard. Ultima V supported two boards, for a total of 12 voices, of which it used eight. Most other programs supported at most one board with six voices.

Applied Engineering's Phasor was compatible with the Mockingboard. It had 4 sound chips and thus provided 12 audio channels. Few programs supported using it for more than six voices, however.

An IBM PC-compatible version was developed, but was only distributed with Bank Street Music Writer. [5]

The Apple II series of microcomputers was initially designed by Steve Wozniak, manufactured by Apple Computer, and launched in 1977 with the Apple II model that gave the series its name. It was followed by the Apple II Plus, Apple IIe, Apple IIc, and Apple IIc Plus, with the 1983 IIe being the most popular. The name is trademarked with square brackets as Apple ][, then, beginning with the IIe, as Apple //. In terms of ease of use, features, and expandability, the Apple II was a major advancement over its predecessor, the Apple I, a limited-production bare circuit board computer for electronics hobbyists.

The AY-3-8910 is a 3-voice programmable sound generator (PSG) designed by General Instrument (GI) in 1978, initially for use with their 16-bit CP1610 or one of the PIC1650 series of 8-bit microcomputers. The AY-3-8910 and its variants were used in many arcade games—Konami's Gyruss contains five—and Bally pinball machines as well as being the sound chip in the Intellivision and Vectrex video game consoles, and the Amstrad CPC, Oric-1, Colour Genie, Elektor TV Games Computer, MSX, Tiki 100 and later ZX Spectrum home computers. It was also used in the Mockingboard and Cricket sound cards for the Apple II and the Speech/Sound Cartridge for the TRS-80 Color Computer.

The Apple II line of computers supported a number of Apple II peripheral cards. In an era before plug and play USB or Bluetooth connections, these were expansion cards that plugged into slots on the motherboard. They added to and extended the functionality of the base motherboard when paired with specialized software that enabled the computer to read the input/output of the devices on the other side of the cable or to take advantage of chips on the board - as was the case with memory expansion cards.

Apple II system clocks, also known as real-time clocks, were devices in the early years of microcomputing. A clock/calendar did not become standard in the Apple II line of computers until 1986 with the introduction of the Apple IIGS. Although many productivity programs as well as the ProDOS operating system implemented time and date functions, users would have to manually enter this information every time they turned the computer on. Power users often had their Apple II's peripheral slots completely filled with expansion cards, so third party vendors came up with alternative approaches with products like the Serial Pro and No-Slot Clock.

<span class="mw-page-title-main">Phasor (sound synthesizer)</span>

Phasor is a stereo music, sound and speech synthesizer created by Applied Engineering for the Apple II family of computers. Consisting of a sound card and a set of related software, the Phasor system was designed to be compatible with most software written for other contemporary Apple II cards, including the Sweet Micro Systems Mockingboard, ALF's Apple Music Synthesizer, Echo+ and Applied Engineering's earlier card Super Music Synthesizer.

Throughout its lengthy, multi-model lifespan, the Apple II series computers lacked any serious built-in sound capabilities. At the time of its release in 1977, this did not distinguish it from its contemporaries, but by 1982, it shared the market with several sound-equipped competitors such as the Commodore 64, whose SID chip could produce sophisticated multi-timbral music and sound effects.

The OPL series are a family of sound chips developed by Yamaha. The OPL series are low-cost sound chips providing FM synthesis for use in computing, music and video game applications.
