Where can I find the "old" map mods?

I first learned about this game through this video years ago: https://youtu.be/djp_0bzr8LA
So I'm pretty nostalgic for the maps featured in it. I used to have all these maps on a computer that's long gone now. Is there anywhere these maps were perhaps archived?

Update: After searching through archived web pages and old YouTube videos. I've managed to find some of these maps. The hard part is actually downloading them as so many links are either dead, not archived, or require me to log into a long gone forum.

Giant Slide - FOUND
"Deadly" - Missing
"Careful" - Missing
Soccer - FOUND nonworking <--- I really want to find this one
High Fall - FOUND
Cage - FOUND

These maps are just a few that were featured in a large map pack back in the day. There were at least 20 maps, but it's unlikely I will be able to find them all.
