Here are some pics
The Wacom circuit board showing the socket the USB lead plugs into.

I took the plug off the lead , just broke it up with pliers , and trimmed the connections on the end and soldered them directly to the Wacom's circuit board.

I covered the ribbon cable feeding the screen with kitchen foil , I don't know if it made any difference but certainly that cable stops the tablet functioning if they are over each other even a fraction.

I put the tablet in with the wire coming out of the side . It just fits without touching the ribbon cable or the brass- coloured strips covering the backlight - my first attempt did touch those and it interfered with the tablet slightly , the cursor kept heading for the bottom of the screen. The USB cable is coming out of the side opposite the USB socket of the iBook but the option of having it go across the ribbon cable I thought too likely to give problems. I put the silver foil that was in the tablet case on the back of the tablet. I fixed it all with parcel tape,,, it is held by pressure from the top case anyway , I don't think it will move.With the tablet this way up it reads "upside-down" until you flip the orientation in the Tablet control software.

The closed-up case ,, it just fits , although I forgot to put the foil shield behind the screen . I'm not sure if it makes any difference , and I think it's so tight a fit the foil might be just enough to stop it closing properly without too much pressure on things.
