Unplug all peripherals and remove the power lead from the computer.
Lay the computer face down on a flat surface and undo-the four case fixing
screws. Gently turn the computer over allowing the screws to fall free.
Put them in a safe place until required again.
Lift the top case including keyboard away from the base of the computer -(
taking care not to strain the ribbon cable) and lay it in front of the
machine.
Installing the Econet Module
Included in the ECONET module upgrade kit are two plastic printed circuit
board support posts. These must be fitted to the main printed circuit
board before installing the ECONET module.
The positions at which these posts are to be fitted are shown in figure 2.
When fitting the P.C.B supports, ensure that the base flange does not
interfere with any component on the P.C.B. To fit the support, insert one
end into the hole in the P.C.B and press down gently.
When the support is correctly fitted, it will not be possible to
withdraw it from the hole in the P.C.B. Care must therefore be taken to
ensure the correct positioning of the P.C.B support before pressing it
home.
When the P.C.B supports are installed on the main P.C.B, the ECONET module
should be placed in position ensuring that:
1. The pins of SKT1 on the ECONET module are aligned with the
corresponding holes in SKT4 on the main P.C.B.
2. The pins of SKT2 on the ECONET module are aligned with the
corresponding holes in SKT5 on the main P.C.B.
3. The P.C.B supports are aligned with the corresponding holes on the
ECONET module P.C.B.
