7. Core board sockets.
There are 3 sockets that need soldering onto the baseboard PCB for connection to the core
board. There are two 25 way socket strips and one 2way socket header that must be
installed. The easiest way to get these connectors into the correct position and ensure that
they are upright is to use the core board as a guide with the sockets plugged onto the pin
strips.
Right side 25 way strip + 2 way socket
Left side 25 way socket strip
Put the core board in location on the main board & ‘tack’ the 2 outer most pins of each 25
way socket strip first. Check that the sockets are as close to the PCB as possible and that
the 2 way socket is in its location at pins 13 & 14 of the 50 way connector position – X6.
Once satisfied that everything lines up correctly, solder the rest of the pins on all 3 of the
socket strips and then remove the core board.
