I have just completed my deign and implementation of a 3 voice programmable
sound generator/Atari joysticks/home control/burglar system using the
GI 3-8910 you mention.  it is an 11 IC design for a S-100 bus and I will
be slowly gearing up for production in limited quanity.  It is for my
Zenith Z-100.  I have had it working for a week now, and I programmed it
to play the theme to Star Wars from a direct encoding of the sheet music.
I hacked the Star Wars data in and a <30 line driver program (BASIC) in
last night.   It sounds unbelieveably fantastic!!  Sorry, but I an not
releasing my design (I worked 4 months on it and it is Version 5.6).
I recall that a complete design for the TRS-80 (sound only - no joysticks
or control features) was in 80 Micro TRS-80 magazine MAY 82.  I flagged
myself a note to get hold of this article, but I never did.  It is
a completely different design approach than my own, judging from a
quick glance at it.   The 8910 is the way to go, but that is my opinion
and a lot of people like the TI 76489A.
  
Cheers,
Gern
