Woehah! Zo'n apparaat heb ik ook nog, en zelfs nog de 800XL uitvoering. Ik ben gelijk ook benieuwd of daar nog wat mee te doen, net zoals de befaamde SID chipz ofzow

Wanneer ik tijd heb ga ik wel ff proberen uit te vogelen of er nog iets mee te doen is.
Ik hou je op de hoogte Arnold, misschien heb jij dr ook nog iets aan......

Dit heb ik alvast gevonden:
The Atari sound commands also relate to BBC and Commodore 64 sound commands in a similar way. The Atari has four synthesised sound channels numbered 0 to 3, with parameters to control frequency - i.e., the note - tone quality - from rasp to clear tone - and loudness respectively. Thus a sound command takes the form Sound 0,212,10,8.
This makes the sound far easier to use than on the BBC, though of course delay loops have to be used lacking the BBC's long string of envelope commands.
The sound quality of the Atari is also better in being output via the TV, instead of using a small built-in speaker.
The limitation of the Atari sound is that Basic only offers notes from 0 to 255. However, as the Atari's tones are divided between 3.5 octaves, there is a reasonable match between tones and at least a few musical notes.
The Atari contains a special custom sound chip called Pokey, and the hardware can be Poked to produce sounds directly. This provides a range of about nine octaves, very close to the Commodore 64.
The Atari also has a further sound facility, which is, I think, unique. It uses a dedicated stereo cassette recorder with one data track and one sound track. This means sound from the tape can be output via the TV, even during the loading of a program, as is done on Atari's Lone Raider game. This makes the Atari ideal for things like learning conversational languages, and for integrating real, not synthetic, voices into programs
More to come...............
