of mounting screws, now is the time to select the correct ones. Do this by gently

trying one of each set of screws, in turn, in the holes in the side of the hard disc.

Look at the mounting cradle to see how it fits in the computer. It sits next to the

floppy drive on the bridge near the front, open side up, with the tapered corners to

the front. It is fixed to the bridge by two screws. Two special taptite screws are

provided which are similar to self-tapping screws in that they form their own

thread. Insert the screws now (without the cradle) to form the thread, and then

remove the one further from the floppy drive. Loosen the other screw a few turns

and leave it in place.

CAREFULLY place the hard disc into its mounting cradle. The side of the disc with

the electronic components on faces downwards. The connector, on one end of the

hard disc, should be at the un-tapered end of the cradle. Adjust the position of the

disc until two screw holes on its side line up with two holes on each side of the

cradle.

When correctly positioned the disc should be completely inside the cradle

and must not be touching the base of the cradle.

your hard disc is a low-profile 1-inch type you should select the lower mounting

position so that a second disc can be added easily.

Secure the hard disc using the correct mounting screws.

Gently lower the cradle and disc assembly onto the bridge in the computer and fix

with the two screws. A magnetised screwdriver will help to prevent screws

dropping out of sight. Check and make sure that you do not trap any cables.

Connecting the cables

Connect the hard disc power cable to the socket on the hard disc. It will only fit

correctly one way round.

Connect the LED cable to the two-pin connector on the

ideA

nterface. It will only

fit correctly one way round.

Connect the ribbon cable from the

ideA

nterface to the connector on the rear of

the hard disc.

WARNING: The cable will only fit correctly one way round but it is possible, by

using excessive force, to damage the pins on the hard disc and fit the cable

ncorrectly. THIS WILL DAMAGE THE HARD DISC.

We know of two kinds of hard disc connector. Type one is shrouded, with a notch

cut out of the shroud to accept the polarising 'bump' on the ribbon cable

connector. Type two just has an open group of pins. Type one may have all forty

pins present but pin 20 is usually removed to provide extra polarisation. If your hard

disc does not have pin 20 removed you will have to extract the small plastic pin

from the corresponding hole on the ribbon cable connector. Use a small sharp pin

or something similar. (There are two connectors on the ribbon cable; only remove

the polarising pin from the connector you are going to use).
