   |A total of 128 base address settings are available. The     |
   |jumpers are a binary representation of the decimal memory   |
   |addresses. Jumper CMP9 is the Most Significant Bit and      |
   |jumper CMP3 is the Least Significant Bit. The jumpers have  |
   |the following decimal values: CMP9=512, CMP8=256, CMP7=128, |
   |CMP6=64, CMP5=32, CMP4=16, CMPA3=8. Jumper CMP10 is always  |
   |on. Turn off the jumpers and add the values of the jumpers  |
   |and convert to hexadecimal to obtain the correct memory     |
   |address. (Off=1, On=0)                                      |
