	You may want to try and get some old issues of the 99'er
magazine.  You ask WHY?  Because the TI 99/4a used TI's 76498a
sound chip which worked *similarly* to the GI AY3-8910/2.  Obviously
the values will be different but it's the general scheme (timings and
frequencies) of how the sounds are produced that will allow you to
re-create them on the different sound chip and maybe learn how to
create your own.  Also, several years ago Steve Ciarcia had a column
(in BYTE, naturally) devoted to the GI sound maker and you may be able
to use some of his examples.  Nonetheless, please let me know of any
libraries or further examples you may come across.  Thanks,
