   | A total of 32 base address settings are available. The     |
   | switches are a binary representation of the decimal memory |
   | addresses. Z10/1 is the Most Significant Bit and switch    |
   | Z10/5 is the Least Significant Bit. The switches have the  |
   | following decimal values: Z10/1=512, Z10/2=256, Z10/3=128, |
   | Z10/4=64, Z10/5=32. Turn off the switches and add the      |
   | values of the switches to obtain the correct memory        |
   | address. (On=1, Off=0)                                     |
