Adding Memory Modules

Your computer comes with either 1MB or 2MB of memory
which is soldered directly onto the main system board. By
installing SIMMs (single inline memory modules), you can
increase the amount of memory in your computer up to 10MB
(for 1MB systems) or 14MB (for 2MB systems).
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 call 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.
