   | A total of 64 base address settings are available. The     |
   | switches are a binary representation of the decimal memory |
   | addresses. A9 is the Most Significant Bit and switch A4 is |
   | the Least Significant Bit. The switches have the following |
   | decimal values: A4=16, A5=32, A6=64, A7=128, A8=256,       |
   | A9=512. Turn off the switches and add the values of the    |
   | switches to obtain the correct memory address. (Off=1,     |
   | On=0)                                                      |
