Note: The Cal Trig MTG, Framework MTG, and 4 Byte MTG are all on CBUS 2,
      MBA 105.

      The Data Buffer And-Or cards for Trigger Tower Reference Sets and
      Large Tile Reference Sets are both on CBUS 2, MBA 106.

      The length of the TSSBUS cable exiting each Tier 1 (Tier 2) BBB should
      be roughly the same. In this way, timing skew will not accumulate (this
      is most important for Tier 2).
