Checked the wikis, ARG stuff, google searched, but I can’t find anything about this specific machine in Questionable Ethics (it’s in the headcrab/bullsquid room after the alien grunt chamber). It is interactable; pressing E on it makes a sound like entering a code failed, but I can’t seem to press anything on the keypad/shoot the buttons or do anything else with it.
It’ll probably be one of the steps needed to uncover the Gonarch hidden in the labs, once they implement it. OOPS
Edit: turns out I was all wrong and a bag of chips, sorry.
