Features q Three independently programmed analog outputs.
> Two 8-bit general purpose I/O ports (AY-3-8910).
> One 8-bit general purpose I/O port (AY-3-8912).
> Single +5 Volt Supply.
13 This Data Manual is intended to introduce the techniques needed to
Scope
cause the AY-3-8910/8912 Programmable Sound Generator to per-
form in its intended fashion. All of the programs, programming, and
hardware designs have been tested to ensure that the methods are
practical rather than purely theoretical.
Although the techniquesdescribed will produce powerful results, the
range of sounds to be synthesized is so vast and the PSG capabilities
so varied that this guide should be viewed merely as an introduction
to the applications possibilities of the PSG.
