<h3>Sound:</h3>
<p>AppleWin emulates the internal speaker, the Mockingboard (or Phasor) sound card and also the SAM card; using a PC sound card.</p>
<p>AppleWin emulates the Apple II's internal speaker, the Mockingboard (or Phasor) sound card and also the SAM card.</p>
<p>Use the AppleWin Configuration tab labelled <em>Sound</em>.</p>
<p>If you want to use a sound card then use at least DirectX&nbsp;9.</p>
<h4>Speaker:</h4>
<p>You can now only emulate this with a sound card.</p>
<h4>Mockingboard:</h4>
<p>When the Mockingboards are enabled, the cards are physically plugged into slots
4 and 5 of the Apple II.</p>
<p>Each Mockingboard is a type 'C': 2x AY-3-8913 (3-channel sound generator) &amp; 2x
SSI263 (speech chip)<font face="Tahoma"><br>
</font>Each AY-3-8913 is fully emulated (tone, noise &amp; envelope).<font face="Tahoma"><br>
</font>Each SY6522 (that controls an AY-3-8913) can generate precise timer
interrupts or phoneme-complete interrupts.<font face="Tahoma"><br>
</font>Emulation of the SSI263 is basic at the moment and only plays back
phonemes at a fixed rate without any support for inflection or filters.<font face="Tahoma"><br>
</font>Additionally the Votrax/SC-01 (predecessor to the SSI263) is emulated by
remapping Votrax phonemes to the SSI263's.</p>
<H4>Phasor:</H4>
<P>When Phasor is enabled, the card is physically plugged into slot 4 of the Apple II.</P>
<P>Phasor is equivalent to 2 Mockingboards: so has 4x AY-3-8913 &amp; 2x SSI263.</P>
<p>Mockingboards can be plugged into slots 4 and/or 5 of the Apple II.</p>

<P>There are a number of games and demos that support Mockingboard (or Phasor), eg:</P>
NB. Some Mockingboard compatible software requires the card to be in a specific slot (usually slot 4).<br>
Some software will allow the user to pick the slot, and better software will auto-detect the slot.
</p>
<h4>Phasor:</h4>
<p>Phasors can be plugged into slots 4 and/or 5 of the Apple II.</p>
<p>A Phasor is roughly equivalent to 2 Mockingboards and has 4x AY-3-8913.<br>
It powers up in a hardware-identical mode to the Mockingboard type 'C', and so is compatible with all Mockingboard titles.<br>
Using software (to access memory mapped I/O) it can be switched to native Phasor mode (4x AY8913s) or Echo+ mode (but without the TMS5220 speech chip).
