I've loved LEGO toys since 1977 and a new user to LDraw and MLCad, I LOVE being able to "build" some of my old creations (from old pictures and memory) and my latest BSG Viper in 3D.  I've read a lot about the "Official Model Repository" but I can't seem to find any links direclty to it (other than the nameing conventions for files).  It would certainly love to see 3D models of my old set that I can't build anymore.

Any help in finding the files is appreciated.  Also, I intend to rebuild my original castle (set 6075 with the yellow bricks) and would be more than happy to upload if it's not already there.
 
Thanks!
