I'm in the middle of a PSX / DESR assembly guide, but my time is limited at present due to family & seasonal commitments. I promise to tidy this all up and complete the guide asap, but in the meantime if you have a PSX / DESR unit and want to see what lurks beneath it's sleek exterior here is a basic guide (incomplete as I stopped at the DVD section as it is clearly rather complex and at 2am I was not up for dealing with it).

I apologise for the rawness of it and the large images, but this will be removed and turned into the more familiar PDF type guide shortly.
