	If this is the first document you've read on AGI, it might be helpful to read a few other tutorials explaining what AGI is, how to program in the logic code and basically how to put a quick game together. There are many other links to tutorials on this site if you wish to have a look.

	<blockquote>''According to Donald B. Trivette, author of ''The Official Book of King's Quest'', a year before the IBM PCjr was announced IBM asked Sierra to create a game that would show off the new computers color graphics capabilities. IBM supplied the company with a prototype Junior, and Roberta set to work designing a new type of adventure game. The game produced was called King's Quest. This is important because the IBM PCjr had a different method of sound generation than the IBM compatibles of today. The sound data was stored to make it easy to send to the Juniors sound generators. This format appears to have remained right through the AGI games up until 1989--90 when SCI took over even though the PCjr had long since been surpassed by the 286, and 386.''		<blockquote>''According to Donald B.

	<blockquote>''Most people who think of AGI games remember that they played their music and sounds over the PC speaker. What they may not know is that all sounds in the MS-DOS, Tandy and Macintosh versions are composed of four parts, one which is the melody, two which are accompaniment, and the final one being noise. The IBM PC can only play one note at a time so all AGI games for the PC play the melody by itself. The Apple IIgs version has much more sophisticated sound: 16 channel wavetable based MIDI songs for the soundtracks, and digitally sampled PCM sound effects.''		<blockquote>''Most people who think of AGI games remember that they played their music and sounds over the PC speaker.
