It is a ibook G4 with a 12 inch screen. Mac OS X version 10.3.5. Processor 1.2 HGZ power PC G4, memory 256. It is loaded with microsoft power point, word and excel. the CD drive and wi fi work. I would consider this lap top in excellent shape with just a few minor scuffs around the case from normal use. Screen is perfect and battery charges and holds a charge. A original apple battery charger is included
