I don't usually correct this, but in her iconic photo she's standing next to printed output of an Apollo simulator run, not the actual source code for the AGC or lunar module.

Edit: this may or may not be true. From what I can find it's probably a combination of both.

IIRC she was running the simulation side of the lab that produced the AGC and LEM guidance software at the time of Apollo 11, then the AGC side, then the unified lab when it was reorganized in 1970.
