Adding Memory

In the future you may want to install memory modules to expand the
functionality of your computer. You can increase memory to 128MB by
installing optional memory modules. There are two memory module
slots in your computer. A 32MB and a 64MB Expansion Memory Modules
are available as optional memory modules.
!
Make sure you observe the proper safety precautions when you install memory
modules in your computer. See "On Upgrading the System" on page 85.
Be careful when adding memory. Mistakes when installing or removing a memory module
may cause a malfunction.
Electrostatic discharge can damage electronic components. Before touching a memory
expansion board, ensure the following:
You are discharged of static electricity by touching a grounded metal object.
You do not work in a carpeted area.
You do not open the package of the memory module until ready for use. The package
protects the memory module from electrostatic discharge.
You use the special bag for preventing electrostatic discharge or use aluminum foil
when you store the memory module.
