UPGRADING ROADRUNNER ON-BOARD MEMORY
The Roadrunner has one on-board SIMM (single inline memory module) expansion slot. SIMM memory
is available in five sizes: 4, 8, 16, 32, and 64 megabytes.
Installing Memory
Special care must be taken when installing a SIMM module. The illustration below shows how the curve
in the SIMM module must align with pin-1 on the SIMM connector.
Insert the SIMM into the connector at a slight angle. After you feel the SIMM module settle into the
connector, rotate the SIMM into an upright position. When the SIMM is properly positioned, the metal
retainer clips at each end of the connector will click into position, locking the SIMM in place.
Very little force is required to install a SIMM module. If you’re having problems getting the
SIMM module installed in the socket, stop and take a moment to examine both the SIMM
module and the socket. Make sure you are installing the SIMM as shown below.
Once the memory is installed, you must set the memory configuration jumpers based on the capacity of
the SIMM module. A table showing how these jumpers are configured is shown in AM-172, AM-174,
and AM-137 illustrations.
To remove a SIMM from its connector, simply press out on the metal retainer clips and gently tilt the top
of the SIMM module, so it is free of the metal retainer clips.
