   |A total of 64 base address settings are available. The      |
   |jumpers are a binary representation of the decimal memory   |
   |addresses. W9 is the Most Significant Bit and switch W4 is  |
   |the Least Significant Bit. The switches have the following  |
   |decimal values: W9=512, W8=256, W7=128, W6=64, W5=32, W4=16.|
   |Turn off the switches and add the values of the switches to |
   |obtain the correct memory address. (Close=1, Open=0)        |
