I have a Titanium Powerbook 550 with 512 MB RAM, 48GB HD, DVD-CDRW, Airport card, and new bag.
Works flawlessly.
Comes with poweradapter and two batteries both hold good charge.
The screen is in good condition no dead or stuck pixels, slight marking on the screen from keyboard that doesn't show when powered on and barely shows when off. I have applied Wild Eepz screen cushions and TiGlide to the hinges for smooth opening and closing. There are some cosmetic paint chips/scrathes, but not bad.
Asking $1200 for all the above.
