                                   Note:

  A total of 255 base address settings are available. The switches are a
  binary representation of the decimal memory addresses. SW1/1 is the Most
  Significant Bit and switch SW1/8 is the Least Significant Bit. The
  switches have the following decimal values: SW1/1=256, SW1/2=128,
  SW1/3=64, SW1/4=32, SW1/5=16, SW1/6=8, SW1/7=4. Turn off the switches
  and add the values of the switches, including an additional value of 512
  as a fixed setting, to obtain the correct memory address. (Off=1, On=0)

                       MISCELLANEOUS TECHNICAL NOTES

  » An optional cable is required to bring out the B side of the switches
  to another 37-pin connector (Port B).

  » The 16REL-L can be installed into any PC expansion slot, except the
  J8 slot on the original IBM XT and Portable.
