I moved to 1 of the pillar screens and discovered there a map of the
Center with a succinct depiction of what was available on each level. It then presented instructions for using the com screens before beginning again, welcoming me to Gamedon.
        Following its suggestion I moved to the nearest cluster of screens surrounded by meandering couches of beige and blue and purchased an access chip which was white with a red chevron. When a station was vacated its screen reverted to various symbols indicating it was free.  White with a blue circle. A red square on green, a golden lozenge on orange. She who possessed the matching category of chip inserted it and gained access to the message files.
