3. Squeeze the noses of the two stand-off clips (2) to
overcome their latching mechanism and pull the 16 bit PCB
fractionally away from the controller PCB at these two
corners. Then grip the edges of the 16-bit PCB at a
position adjacent to the multipin plug and pull it away
from the controller PCB.
4 Install the 16-bit/PIC board in place of the 16-bit PCB
which you have just removed.
3. Re-install the controller PCB and carry out a complete
diagnostic check of the NCR DECISION MATE V.
Installation of the 16-bit/PIC board on a multilayer
controller board which has not previously contained a 16-bit
PCB:
1. Remove the multilayer controller printed circuit board
from the computer. This procedure is described in the
Service Manual for the NCR DECISION MATE V.
2. Refer to Figure 2 which shows the multilayer controller
PCB from the component side. Remove the four screws
marked 1 in this Figure.
If the 96-pin socket J107A (supplied with the Kit) is not
already present, additionally remove the screws marked 3.
Then remove the metal plate containing the adapter
retention clips, taking care not to misplace the spacer
washers. Then solder the socket into place, so that the
cut-out corners of the socket are on the right-hand side
when viewing the solder side of the controller board with
the socket in a bottom left position. Replace the metal
plate with screws 3 and their spacer washers.
3. Insert the bases of the two PVC stand-off clips into the
pre-drilled holes (2) from the solder side of the
controller PCB.
