IMHO using a Carte Blanche to provide a IIgs with stereo sound is a
bit like using a stretch Hummer to take the kids to school - waaaay
overkill.  ;-)

All of the signals are already provided via a pin socket on the
motherboard. All that is required is to demultiplex the separate
signals and filter/amplify. This is what the TDX board outlined here
does: http://home.swbell.net/rubywand/Csa2SOUND.html#005

Does the TDX board work? - yes

How do I know it works? - coz I built one! See
http://apple2.sytes.net/TDX_Stereo_Card/index.html

Thats my 2 cents worth.
