   | A total of 64 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    |
   | Z10/6 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, Z10/6=16. Turn off the switches and    |
   | add the values of the switches to obtain the correct       |
   | memory address. (On=1, Off=0)                              |
