      Rampage

  Note: The Rampage AT may be set for any memory address from 0K to
  15896K, Each switch represents a quantity of memory. SW2/1 is the Most
  Significant Bit and SW2/7 is the Least Significant Bit. The switches
  have the following values: SW2/1=8192K, SW2/2=4096K, SW2/3=2048K,
  SW2/4=1024K, SW2/5=512K, SW2/6=256K, and SW2/7=128K. Turn off the
  switches and add their values to obtain the correct starting memory
  address. (Off=1, On=0)
