Ok so I am replaying Fallout 1 and I need some tips about the confrontaition about the Master.

I read that is three ways to deal with him:

1. Fight him head on

2.Convince him to kill himself using evidence that Super Mutants are inferior.

3. Activate the Self Destruct yourself


I am trying to do the second option, but where do I get the evidence to have the dialoge option, All I know is to find it in a computer but where is the computer?

SPOILER ALERT
SPOILER ALERT

The Head Scribe of the Brotherhood of Steel, Vree, has been doing autopsies on super mutants. If you ask her about it, she'll give you a holodisk with information that exposes a fatal flaw in the Master's plan.

Spoilers

Did it and I beat the game again, and man that ending still gets me everytime, this image invokes sadness:
