I am thinking of getting the TWEETIE board. I was wondering if anyone out there can tell me if it is true stereo or just the same sound on two channels? None of the things I have written have specified values for the left or the right channels so how does it work, any ideas? Jim Patterson

|     I believe that it splits the sound into three different voices and the
    you have the choice of which two voices you merge back together to
    leave you with a 2 channel (stereo effect). There was a review in a UK
    mag St User or ST format about September 1989.

    I don't know nothing about Tweetie, but the soundchip of my 1040
    has three channels (I'm not sure, it's a long time ago when I did
    it. Could be two as well) which are mixed together to drive the
    monitor's speaker. I splitted the channels directly at the chip
    and guided them to two cinch outlets. Internaly I mixed them together
    again for the monitor with some resistors. Because each of the channels
    of the soundchip are programmable, you get a nice "pseudo"-stereo
    effect. Specially with some games like Silent Service, where the
    gun is on the left (in my configuration) and torpedos on the right.
    The sound of the engine comes through both speakers. The cinch outlets
    are connected to a small stereo amp b.t.w.
