  Note: A total of 752 memory base address settings are available. The
  switches are a binary representation of the decimal addresses. Switch 2
  is the Least Significant Bit and switch 7 is the Most Significant Bit.
  The switches have the following decimal values: switch 2=16, 3=32,
  4=64, 5=128, 6=256, 7=512. Add the values of the on switches to obtain
  the correct memory address. (Off=0, On=1)
