I am a past TS user .. still have all the boxes and CDs here

I went looking online to see was TS being unofficially updated and arrived at:
http://truespace3d.free.fr/index.php/truespace-7-6/
I am downloading from that link, quiet slow, and also nervous of its providence because it takes you off to a strange looking download page.
Then from menu at that site above I arrived here.
Many different threads about latest updates and the like but it seems it requires a previous installed version?
So what is the best place to start download wise?
( I realise the Modelside/Workspace side thing .. no harm in both I suppose )
