Pretty sure they've always "owned" it.. that said, it's fully archived on http://archive.org, including the add-on files for 3400/2400, compatibility list, etc.
EDIT:
hmm.. seems 2dfx makes an interesting point, that if 1.2.2 is newest, it's not there?
can anyone confirm 1.2.2 as the latest, not 1.0.1 that's posted?
Maybe this will fix some of my instabilities?
