Apple 12/600PS manual J10

7Insert the SIMM into the connector at an angle and press the SIMM into the retaining clips on each end of the connector until the clips snap and fasten the SIMM in place.

Hold the SIMM over the slot, aligning the connectors and notches with the controller board’s connector. Notice that one edge of the SIMM has a distinctive notch that you can use to judge the orientation and alignment of the SIMM with the connector. This notch, on the bottom edge of the SIMM, should be down as you install the SIMM.

WARNING To avoid damaging or scratching the printed circuits when installing a SIMM, don’t touch the controller board with hands or tools.

If you are installing two SIMMs, install one in slot

J10 first. (This makes access to the J11 slot easier.)

Insert the SIMM at an angle.

Rotate the SIMM until the retaining clips snap into place.

Depending on the amount of memory you’re installing, you may need to install one or two SIMMs, and perhaps remove a SIMM from a slot in order to insert one that has more memory. For example, when installing two 16 MB SIMMs, you must remove the 4 MB SIMM from the J11 slot.

To remove a SIMM, carefully spread the retaining clips at the base of the installed SIMM, then rotate the SIMM until it can be pulled free of the slot.

8Repeat step 7 to install the second SIMM if necessary.

9Remove the grounding wrist strap.
