            Note:A total of 255 base address settings are available. The
            switches are a binary representation of the decimal memory
            addresses. SB2/7 is the Most Significant Bit and switch SB3/6
            is the Least Significant Bit. The switches have the following
            decimal values:SB2/7=512, SB2/8=256, SB1/8=128, SB1/7=64, and
            SB1/6=32. Turn off the switches and add the values of the
            switches and convert to hexadecimal to obtain the correct
            memory address. (Off=1, On=0)

  switches have the following values: SB3/1=1, SB3/2=2, SB3/3=4, SB3/4=8,
  and SB3/5=16. Turn off the switches and add the values of the switches
  to obtain the correct user number. (Off=1, On=0)

  CPU Socket       CN1

                       MISCELLANEOUS TECHNICAL NOTES

  To install the MATH/16 Coprocessor daughter card, remove the CPU from
  its socket on the PC-SLAVE/16N, and install it in the socket on the
  daughter card. Then insert the daughter card into the socket from which
  you removed the CPU on the PC-SLAVE/16N card, so that the pin 1’s on
  the daughter card are pointing in the same direction as the pin 1’s of
  all the chips on the PC-SLAVE/16N.
