+AppleWin emulates the Apple II's internal speaker, the Mockingboard (or Phasor) sound card and also the SAM card.
Use the AppleWin Configuration tab labelled Sound.
If you want to use a sound card then use at least DirectX 9.
+You can now only emulate this with a sound card.
+When the Mockingboards are enabled, the cards are physically plugged into slots - 4 and 5 of the Apple II.
-Each Mockingboard is a type 'C': 2x AY-3-8913 (3-channel sound generator) & 2x
- SSI263 (speech chip)
- Each AY-3-8913 is fully emulated (tone, noise & envelope).
- Each SY6522 (that controls an AY-3-8913) can generate precise timer
- interrupts or phoneme-complete interrupts.
- 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.
- Additionally the Votrax/SC-01 (predecessor to the SSI263) is emulated by
- remapping Votrax phonemes to the SSI263's.
When Phasor is enabled, the card is physically plugged into slot 4 of the Apple II.
-Phasor is equivalent to 2 Mockingboards: so has 4x AY-3-8913 & 2x SSI263.
+Mockingboards can be plugged into slots 4 and/or 5 of the Apple II.

+ NB. Some Mockingboard compatible software requires the card to be in a specific slot (usually slot 4).
+ Some software will allow the user to pick the slot, and better software will auto-detect the slot.
+
Phasors can be plugged into slots 4 and/or 5 of the Apple II.
+A Phasor is roughly equivalent to 2 Mockingboards and has 4x AY-3-8913.
+ It powers up in a hardware-identical mode to the Mockingboard type 'C', and so is compatible with all Mockingboard titles.
+ 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).
