Adding Memory Modules
Your computer comes with 2MB of memory. By installing
SIMMs (single inline memory modules) on the main system
board, you can increase the amount of memory in your computer
up to 16MB.
Caution
It is best to have your dealer install memory modules for you
because they can be damaged easily if installed incorrectly.
If you prefer, you can install your own SIMMs by carefully
following the instructions in this section. However, you could
transmit an electrostatic discharge and damage your
components; so read this entire section before you begin.
Before you install SIMMs, check the following guidelines to
ensure that they will work properly:
❏ Use SIMMs that operate at 70ns (nanosecond) access speed.
Be sure all the SIMMs have the same access speed.
❏ Use the correct SIMM configuration to add the amount of
memory you want. See the table on the next page.
Once you have the SIMMs you need, you or your dealer can
install them in your computer. If you are going to install them
yourself, follow the instructions below.
