Vertex/Pixel Programming

I’m looking for a good tutorial on how to program with ATI pixel shaders. What is the address of ATI developer and demos pages?
Thanks.

Unf***ing believable! It’s ATI !

The SIGGRAPH 2001 Shading Course Notes are the best reference for this. For fragment shader sample code, grab the R8500PointlightShader sample app.
