old documentation

I need to use the old version of CUDA.
Where can I find the old documentation?

it’s bundled with the CUDA toolkit installer.

If you want to get documentation for CUDA 6.5, install the CUDA 6.5 toolkit. The CUDA 6.5 documentation will be installed along with the toolkit.

For example, on a typical linux install, it will be in:

/usr/local/cuda/doc

NVIDIA does not maintain a comprehensive online version of all previous documentation families.
