                                   Note:

  A total of 64 base address settings are available. The switches are a
  binary representation of the decimal memory addresses. Z10/1 is the
  Most Significant Bit and switch Z10/6 is the Least Significant Bit. The
  switches have the following decimal values: Z10/1=512, Z10/2=256,
  Z10/3=128, Z10/4=64, Z10/5=32, Z10/6=16. Turn off the switches and add
  the values of the switches to obtain the correct memory address. (On=1,
  Off=0)

             MISCELLANEOUS TECHNICAL NOTES

  Exact location of jumpers W1 & W2 is unidentified.
