Terminals in the HRA Lab require appropriate cards. The cards are easy to find - they are scattered throughout the room.

The next page of the guide to Control has the solution to the puzzle encountered during Old boy's club mission.

The puzzle's solution:
After inserting the cards with symbols in the right place, you will unlock the main terminal. You can continue the story.
