Loosen the ribbon cables connecting the keyboard to the computer by using a plastic opening tool to lift the tabs on either side of the cable port.

Gently remove the ribbons from its tabs.
I did find that, strictly speaking, you don’t need to remove the ribbons. If you carefully hold up the keyboard up towards the screen with one hand, you can remove the old RAM and install the new one with the other. I suppose you could also use a length of masking tape to hold the keyboard up.
I found it easier not to remove the ribbon, especially as I couldn’t find my plastic opening tool.

Gently wiggle the RAM card to loosen the connection until it pulls free.

Disconnect the wires from the port.
Speaker panel? I don’t think this is correct - I accidently pulled the black & red wires out from this part and sound still worked fine. Is this instead a battery connection?
thats correct, that red/black wire comes from the green Varta battery under the speaker panel. This PRAM battery most of the time has gone bad since the 90s and it's electrolyte fluid dropped down onto the main board, destroying other parts.

Note that the side panels should be placed back BEFORE the audio panel.
right, also I often had problems with placing the audio panel back into its place, it's three little plastic noses just didnt want to fit back into its notches of the back.
