Oh, this is going to be easy.

Now we're getting down to brass tacks. Here the battery case has been removed and the sides of the phone separated. Also, you can see the button pad and the conductive disks under each rubbery region.

Here we see the button board. Each rubber pad segment hides a conductive disk that connects each side of the button area, completing the circuit and sending a signal to the chip. You can also see the LED and speaker, which are affixed snugly to the case (for now.)

Three 1.5V lithium batteries and their former home.

Behind the button leads, there lines in and out for the speaker (top), power (bottom left), and the LED (bottom right).

Somewhere under that dot is a cool chip that they won't let me see. Feh!

The LED shines into this little piece of plastic, which spreads the light out over the whole "screen." Cool effect for cheap.

Took a little work, but I freed the LED from the front of the case.

Finally pulled the speaker out of its socket.

16 ohm, .25 watt speaker. Not too shabby.
