Control: how to use the cards to activate the HRA machine

The procedure to follow begins in the mission of Control “Old Boys' Club”. In fact, once we meet Marshall, we will be asked to solve a puzzle that asks to restart the punch card terminals and then activate the HRA machinery. What is the quickest method to follow? First of all you have to collect the five yellow punch cards, each with a different symbol. These are quite easy to locate, as the boards are in the immediate vicinity of the HRA machine and also upstairs in a separate room. 

The punch cards, numbered according to the terminal to be used for each.

Once you have all five cards, you need to insert the right one into each numbered terminal. Terminal numbers can be found by looking at the shapes taped on the sides of them. This puzzle can be solved more easily by looking at the white boards in the main room and the one upstairs. Each puzzle will give a hint as to where it goes into Control each card to activate the HRA machine. Once the puzzle is solved, you will be able to access the machine in the center of the room. Once completed, you will be able to reactivate in Control the HRA machine and complete the mission.
