Argh, that's annoying. I probably should have cached some copies :-(
We do have random old versions lying around on CD, but I've been disposing
of those since they were all online.
A problem with using old versions is they typically need a licence key:
Altera previously offered free keys for old versions, but I'm not sure if
that's gone too.

which is the best URL the Wayback Machine can offer me:
The download URLs are typically fairly predictable, although they change the
formatting periodically. My quartus-install tool:
goes back to 13.0sp1 - if I can find out the URLs for older versions I'll
add them (pull requests also welcome). It doesn't currently make much
effort for the Windows versions since we don't have a need for those, but no
reason why that couldn't be added.
