Acorn ECONET Manual

Fitting an ECONET module

Note that any modification or upgrade carried out to the printed circuit board of any
Acorn equipment is undertaken at the sole risk of the person carrying out the
modification or upgrade. No claim for loss or damage to the equipment caused by the
modification or upgrade of the printed circuit board by unqualified personnel shall be
accepted by Acorn Computers Limited.
WARNING - A number of the components used within ACORN equipment are STATIC
SENSITIVE. All usual anti-static precautions must be taken to prevent damage to these
devices.
Before attempting this upgrade, please read all the instructions carefully. If you are in
doubt about your ability to carry it out, the ECONET module and the microcomputer
should be taken to your nearest authorised Acorn dealer.
A charge may be levied by the dealer for installing the ECONET module; such a charge
shall be entirely at the discretion of the dealer concerned.

Dismantling the microcomputer

Before attempting to fit the ECONET module to your machine, first ensure that the unit
is disconnected from the mains power supply.
The upper half of the case must be removed from the unit to allow access to the main
printed circuit board. To do this, turn the computer upside down and place it on a firm,
flat surface; locate and remove the four fixing screws that hold the upper half of the case
in place. These screws are located on the underside of the unit, two at the rear and two at
the front of the machine, and are labelled 'FIX'. Please note that the two fixing screws
fitted to the rear fixing positions are longer than the other two.
When the fixing screws have been removed, carefully re-invert the computer whilst
holding the two halves of the case together. The upper half of the case may now be
removed by lifting it directly upwards from the machine.

Machine orientation

Within this fitting instruction, the points of the compass are used to indicate the way in
which things are orientated. With the machine positioned such that the keyboard is
nearest you and uppermost, the nearest edge is designated to be SOUTH, the rear
NORTH and right and left are designated EAST and WEST respectively.
The ECONET module will be installed in the NORTH-EAST corner of the main printed
circuit board
