wires and speaker connectors _inside_ the GS's case (I damaged a pair
of speakers having to wedge the 1/8" phono's tail up against the back
of the case).
The only stereo/digitizer board you can still purchase new is
the Alltech (formely Econ) SoundMeister card. It's an average card,
it works but nothing to say beyond that. I list it here because you
can still buy it, not because it was an exceptional card. There are
of course other cards out there, but they're mostly mediocre ones
(speaking of mediocre, avoid the AE SonicBlaster, that was a poorly
designed card that wasn't properly shielded and had problems with
output at certain levels I recall).

The Phasor:
Well the Phasor was an optional plug-in board designed for the
Apple II Plus and IIe (which had no sound capabilities built-in,
other than a speaker which could be toggled on/off to produce a
click or beep like PC's). It used 4 General Instrument AY-3-8913
sound chips, an SSI-263 speech chip (with the option of adding
a second) and had a built-in 4 watt amplifier which could output
in true stereo. There were DIP switches on the card which would
allow it to emulate other Apple II sound cards, such as the old
Mockingboard or Echo+ speech card (I was never able to get the
latter emulation to function).
Each AY-3-8913 (identical to the AY-3-8910 as far as I know,
only it came in a smaller package) could produce 3 independant
voices, plus a 4th channel for a white noise generator. With all
the chips combined, that gave it 12 voices, 4 white noise channels
and 1 or 2 synthesized speech channels. The AY-3-8910 could be
used to produce sounds and music and was commonly used in old
arcade machines in the 80's (not to mention a couple of computers,
like the TI99/4a, Intellivision, Atari ST, etc). It was limited
