Ok, i was doing some work with Mac Ports on an old 10.7.5 machine (9 year old iMac still works great). I realized that i needed an Xcode install for 10.7.5. I spent hours trying to find links to old Xcode versions on Apple’s Developer site. They are gone. Broadening my search to google, I found this amazing trove of links. I am posting them here for my own selfish reasons, but i linked to the original post. Why must Apple insist on deleting the past. enjoy them while they still work.
(you will need to be registered as an apple developer for these links to work. Anyone can do it and it is free.)
