Isn't anyone keeping an archive of the old versions of knoppix?

For me, googling for specific old versions seems to just bring up innumerable old-md5 references.
E.g., it doesn't seem to find any copies of KNOPPIX_V3.1-31-10-2002-EN.iso at all.
There's a knoppix 3.3 here: http://www.neei.uevora.pt/pub/ISOs/knoppix/
But I've not found any site that is keeping a collection of Knoppix releases.
