+<p>There are several ways to disassemble the Archos Jukeboxes.
+Here is an approach where you don't need to bend any metal parts.
+
+
+<p><img src="b10.jpg">
+<br>
+First, remove the battery covers and unscrew all 8 visible screws: 2 torx screws on the left and right sides, and 2 small philips head screws on the top and bottom. Then you simply lift off the plastic top cover.

+<p><img src="b5.jpg"> <img src="b6.jpg">
+<br>
+Use your thumb nails to compress the thin edge of the rubber while gently pulling the metal plate over it.
+<hr>
+
+<p><img src="b7.jpg"> <img src="b8.jpg">
+<br>
+Do the same on the side.
+<hr>
+
+<p><img src="b9.jpg">
+<br>
+You have liberated one end of the Archos from the metal back plate!
+Now lightly lift the blue rubber bumbers up from the circuit board on the other end, then slide the Archos out of the back plate.

+<p>The CPU board is connected with a 40-pin connector, that you have to disconnect by carefully pushing it down on both sides. Use a semi-soft rounded plastic tool. DO NOT USE A SCREWDRIVER! There are delicate traces on the CPU board that you DON'T want to damage!

+Ah, there. The top board is separated from the bottom (CPU) board and folded out to the side.
+
+<p>The CPU board can now be removed by carefully pulling it off its' connector to the MP3REAR board.
+
+<p>Most likely, your unit will have less patch wires than this and might have a different set of power components on the left. That's because this is a Really Old Model&trade;, made back in the 20th century (week 44, 2000) :-)

+#define _PAGE_ RS232 converter
+#include "head.t"
+
+<h2>What is this?</h2>
+<p>
+This is an RS232 converter for interfacing a PC with an Archos Jukebox (or any other device with a 3.3V serial port). It converts the PC serial port signals to 3.3V levels. The design is very straightforward, using a standard MAX3232 transceiver.
+
+<h2>How to power it the easy way</h2>
+<p>
+It takes its power from the DTR signal in the serial port, so the communication software in the PC must set the DTR signal ACTIVE for this to work. It might still not work on some laptops, that may have a weak driver for the DTR signal.
+
+
+<h2>How to power it the safe way</h2>
+<p>
+It is also possible to take power from the USB port, or another 5-10V source. Just remove the D1 diode and connect the power to the +5V and GND pads.
+
+<h2>How to make one</h2>
