6.2.2 SIMM Installation
To install the SIMMs in the sockets, proceed as follows:
1. With the board flat on the table, turn it so that
the front plate is on the left.
2. Hold the module with the notch on the bottom
right facing you, and insert the fingers into the
socket at a 70° angle from the board. Always
start inserting the module in the socket nearest
the top edge of the board
3. Snap the module to a vertical position in the
socket. The module is fully inserted when the
retaining pegs snap into the holes at each end
of the module.
4. Work your way by inserting the other
modules, one by one, towards the lower edge
of the board.
To remove the SIMMs from the sockets, pull on the retaining pegs located on each side of the
SIMM socket. Once the module has snapped out of the socket, pull gently on it.
