4 MEMORY UPGRADES
Read this chapter before purchasing any memory upgrade
and if in any doubt consult your supplier. Then, if having read the
relevant instructions, you still do not feel confident about installing
the upgrade, you may wish to have your supplier or service
organisation install it for you.
Caution
Apricot Computers Ltd have extensively tested many combinations of memory
and all of our upgrade parts are guaranteed. We cannot guarantee the quality
or compatibility of components obtained from any other source.
Appendix A, “The System Unit”, provides an overview of anti-static
precautions, instructions on removing the top cover and the
appendix B ‘System Motherboard’, an outline guide showing all of the
appropriate memory locations.
The only tool required to complete the installation of many of the
upgrades is a small cross-head screwdriver.
Warning
Never carry out any work inside the computer with AC power applied. Turn
off the computer and unplug all power cords before starting work.
Adding more system memory
The computer’s motherboard is fitted with sockets for up to four
SIMMs (single in-line memory modules). You may need to add more
memory if you want to run complex operating systems or large
application programs.
The SIMM sockets are located at the front of the motherboard. Each
pair of sockets, or bank, can be fitted with SIMMs. SIMMs with
capacities of 2, 4, 8, 16 or 32 Mbytes are supported, giving a
maximum capacity of 128 Mbytes.
SIMMs must be fitted in pairs and the pair must be identical.
