Removing SlMMs
If you need to remove SIMMs from your computer (to install
different ones, for example), follow the steps below:
1. Remove any option cards that may be blocking your access
to the SIMM sockets. (See page 3-17 for instructions.)
2. Use your fingers or a small screwdriver to carefully pull
away the metal tabs that secure the SIMM at each end, as
shown below. As you pull away the tabs, the SIMM falls to
the side. Remove it from the socket.
3. If necessary, follow the same procedure to remove the other
SIMM.
