The switches are a binary representation of the decimal memory addresses. SW1/1 is the Most Significant Bit and switch SW1/6 is the Least Significant Bit. The switches have the following decimal values: SW1/1=512, SW1/2=256, SW1/3=128, SW1/4=64, SW1/5=32, SW1/6=16. Turn off the switches and add the values of the switches that are off to obtain the correct address. (Off=1, On=0)
