   |------------------------------------------------------------|
   | A total of 134,217,728 address settings are available.     |
   | Switches S1 through S7 set the hexadecimal memory address. |
   | SW1 is the Most Significant Nibble and switch SW7 is the   |
   | Least Significant Nibble, though the bottom two bits of    |
   | SW7 are always 0. The switches have the following decimal  |
   | weight values: SW1=4,194,304, SW2=2,097,152,               |
   | SW3=1,048,576, SW4=65,536, SW5=4,096, SW6=256, SW7=16. Set |
   | the switches, multiply the number on the switch by its     |
   | weight value, add the values obtained for each switch, and |
   | round down to the nearest multiple of 64 to obtain the     |
   | correct memory address.                                    |
