  Note: The system memory card uses proprietary memory modules, some
  require only one module space on the memory board, while others require
  two. In the cases where a double size module is used, the following
  space is marked with "-----------------", designating that space as
  occupied.

  the following space is marked with "-----------------", designating that space as occupied.
