If you have the Apple Sound Balls which ship with an iMac or can be bought separately, you can connect them to your Powerbook and iBook via the Firewire port for electricity and the plug then goes into your headphone port. I am listening to them now, Willie Nelson!, and amazed at how good such a small speaker can sound...somewhat helped by the loss of hearing of the high freqs. --- Trees are being sucked dry of life in South Florida by a tiny insect. <http://www.lobatelacscale.com>
