I was thinking that as well, but I find nothing there for my hardware. Strictly speaking, I think it would be illegal for archive.org to distribute the software. But archive.org likes to dabble in the grey, test what it can get away with, and likely has a good legal team to fight off attacks. I’ve found s/w there that would be even harder to defend than drivers, so I think archive.org would put their neck on the line in this case. But I guess someone needs to upload the software first.

In principle, softwareheritage.org and sfconservancy.org would perhaps also be good candidates for this kind of mission. But ATM their focus seems to be on source code.
