       Note: A total of 255 base address settings are available. The
       switches are a binary representation of the decimal memory
       addresses. Switch A9 is the Most Significant Bit and switch A5 is
       the Least Significant Bit. The switches have the following decimal
       values: switch A9=512, A8=256, A7=128, A6=64, A5=32. Turn off the
       switches and add the values of the switches that are off to obtain
       the correct memory address. (Off=1, On=0)
