CUDA toolkit older version page not found

I am trying to get the simulator gem5-gpu working.

But unfortunately it was only tested on CUDA toolkit 4.0.
the archives website has links to install older versions, but the urls follow to webpages with "page not found.

the gem5-gpu simulator does not run with the newer versions(i tried).

Is there any other way i can install the older versions?

gem5-gpu link: GitHub - gem5-gpu/gpgpu-sim_distribution
