expansion cards. Your supplier will know what upgrades are available. For example,
you can expand your computer's memory by fitting extra RAM.
You should receive precise fitting instructions for upgrades or expansion cards when
you buy them from your supplier. However, to be able to fit them, you first need to
know how to remove the computer's cover and what to look for inside.
Acorn Computers Limited cannot accept any liability for damage done to the product
during the installation of internal upgrades whether or not carried out in accordance
with the instructions in this chapter. If you don't feel confident about carrying out any
of the instructions in this chapter, ask your supplier to fit upgrades for you (a charge
may be levied by the supplier for installing any upgrades; such a charge shall be
entirely at the discretion of the supplier concerned).

Before you start

You'll need a small cross-head screwdriver, and a firm, flat, non-slippery surface to
