            Note: A total of 32 base address settings are available. The
            switches are a binary representation of the decimal memory
            addresses. SW1/8 is the Most Significant Bit and switch SW1/4
            is the Least Significant Bit. The switches have the following
            decimal values: SW1/8=512, SW1/7=256, SW1/6=128, SW1/5=64,
            SW1/4=32. Turn off the switches and add the values of the
            switches that are off to obtain the correct memory address.
