INSTALLATION

8.

Pull off the speaker ConnecTOR from the speaker pins underneath the

 

connector. The speaker connector is identified in Figure 2.8.

9.Remove the CPU and MMU from the motherboard. These components are identified in Figure 2.8.

Using a small metal spoon, as Figure 2.10 shows, insert the bowl and of the spoon between the CPU and MMU and their respective sockets. Rock the spoon back and forth to loosen the component from the socket at one end. Repeat this on the other end until the components are loose enough to remove by hand.

Alternately, you may use a knife or small screwdriver to pry up the chips if a spoon with a small enough lip is not available.

Be careful when removing the CPU and MMU that you do not accidently hand their pins. If you do accidently bend a pin, carefully use a small needle nose plier to straighten out the pin.

Plate the removed CPU and MMU on the soft cloth.

Disassembly is now complete.

Preparing The Card

1.Insert the removed CPU and MMU into the MultiRam C Card. As Figure 2.8 shows, the CPU should be inserted into the lower socket and the MMU the upper socket, just as they are located on the motherboard.

To insert the components, line up the pins of the CPU and MMU with their respective sockets holes on the card. The notch on both components should face to the left towards the RAN on the card. Insert one aide of the components pins slightly into the socket. Then, using an inward pushing/rocking motion, seat the pins on the other aide of the component.

If the pins do not easily seat, you may need to very slightly bend all pins on one side of the component inward. Place the component on the table on its side. Lift the component slightly up so that pressure can be uniformily applied to all pins along one side. Apply firm, even, gradually increasing pressure until some small inward movement in the pins is detected. Do not apply too much pressure or the pins will bend too far. Repeat the procedure on the opposite side. Retry inserting the component. Repeat this procedure again if the pins are still too far outside the socket to he moved into the socket holes.

2.Insert the six keyboard support posts into the six holes on top of the card. Insert the two longest posts into the holes at the top left corner and center of the card as Figures 2.11 and 2.12 show. Insert the four short posts into the four remaining holes on the card. Do not change the position of the four short pins which are on the bottom aide of the board.

Insert the end of each pin with the longer collar into the holes. You can insert the end with the shorter collar into the holes but the pin will be harder to remove later it the pin must be removed for any reason.
