Could Atlantis's database contain the knowledge needed to replace its equipment?
Short answerIt ought to, but that knowledge has not been made usable in the examples discussed. Translating instructions for power systems should come first, followed by weapons and Puddle Jumpers.
NotesOne explanation offered for the missing knowledge is damage or inaccessibility in the archive. Another is that the material exists but still needs translation. Atlantis has an extensive database and an interactive instructor, which makes the lack of usable manufacturing instructions frustrating. The proposed priority is to recover instructions for power generation, then weapons and replacement craft.
