Reminds me of this recent video on recovering Luminary 69, Apollo 10's lunar module code (the only known copy of which is somewhere in solar orbit) by careful reconstruction of the development process: https://www.youtube.com/watch?v=-JTa1RQxU04

This exploitation of side-channels is something to pay attention to. Data is rarely fully lost!

In that case someone found a listing of the checksums of the code that launched in the archives (!), that could be used to verify the reconstruction. I wonder if there's anything like that for 2.11BSD
