  Note: A total of 256 base address settings are available. The switches
  are a binary representation of the decimal memory addresses. SWB/8 is
  the Most Significant Bit and switch SWB/1 is the Least Significant Bit.
  The switches have the following decimal values: SWB/1=2, SWB/2=4,
  SWB/3=8, SWB/4=16, SWB/5=32, SWB/6=64, SWB/7=128, SWB/8=256. Turn off
  the switches and add the values of the switches that are off to 512 to
  obtain the correct memory address. (Off=1, On=0)
