Net/MacLand:

  I need information concerning the pinout of the Mac Sound chip.  I am
interested in utilizing the four voices as four individual D/A converters,
and this cannot be done without at least a couple hints.  Sound signals
from the chip are, I believe, encoded by one data line (monophonic,) while
four voices can go into this monophonic output.  I'd like a way to access
those four voices (electronically), but this requires more info on the
sound chip itself, and the SY6522 chip (the Synertek _Versatile Interface
Adapter_ or _VIA_ chip.)

  Information or pointers towards information much appreciated.
