AppleWin emulates the internal speaker, the Mockingboard (or Phasor) sound card and also the SAM card; using a PC sound 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.
There are a number of games and demos that support Mockingboard (or Phasor), eg:
SAM (Software Automatic Mouth) is an 8-bit DAC card than can be enabled in slot 5.
