3. Remove the 3 screws from each side and 2 screws from the backpanel
which hold the chassis lid in place.

NOTE: BE VERY CAREFUL NOT TO BREAK ANY PORTION OF THE
SIMM SOCKET OR SOCKET CLIP WHEN REMOVING OR
INSTALLING SIMMS. THIS IS AN ITEM WHICH CAN BE
REPAIRED ONLY BY REPLACING THE MAIN BOARD AT THE
FACTORY!
6. Starting with the SIMM in the socket closest to you, gently move the clip
on one end of the socket to release the edge of the SIMM.
7. Gently move the clip on the other end of the socket to release the other
edge. When both edges are released the SIMM will rotate forward
(toward you) at a 45 degree angle.
8. Carefully remove the existing SIMM by pulling it towards you and set it
aside.
9. Repeat Steps 6 through 8 for each of the remaining SIMMs, each time
moving to the next socket away from yourself.
10. Starting with the SIMM socket farthest away from you, with the notched
edge of the SIMM pc board on your right, insert one of the new 4
Megabyte X 8 (or 9) SIMMs in the socket at a 45 angle (toward you). The
insertion angle for the new SIMMs is the same angle you used when
removing the previous SIMMs.
