Looks like old Microsoft's FixedSys font.

Aaaaaah Fallout love the game

I had a look in the game files for you and it seems to use the standard "Roboto" font for UI and for terminals it uses Google's "Share Tech Mono"

I had a look in the game files for you and anyone else who comes here to find out and it seems to use the standard "Roboto" font for UI and most other things, while terminals use Google's "Share Tech Mono" font, although many people also assume it is Microsoft's old FixedSys or an altered variation, in the game's files it labels it as Google's "Share Tech Mono" font.
