    Hi all

    I have a CD player I wish to convert to play MP3's ..... the issue is that
    it is a fairly expensive SONY 400 player and I imagine what I have to do is
    identify the appropriate circuitry/board that handles the PCM stream and
    change/modify it. I just have not heard of anyone else ever doing this - and
    I wouldn't except for the desire to retain the player and add this

    emails gratefully accepted

    It's a very large task.
    Essentially, you have to totally throw away the existing circuitry,
    and build a MP3 player compatible with the mechanism.
    You can't simply modify the PCM stream handling logic, as you've got
    to add the ability to do random access to the disk, and support the
    ISO9660 filesystem.
    Once you rip out the bits you can't use, there is little left.
    I don't know much about the Sony 400.
    What's so nice about it?

    ess has a chip, you figure out how to get to the ide port if it has one,
    bypass pcm, add an lcd, use the buttons on front like normal, supports
    cd's and stuff, can be used with hard drives. i have a pdf for it on my
    site, somewhere.
