The bottom of the unit reads macintosh powerbook g3 series 400mhz/1mb cache/64mb (upgraded to 128mb)/6gb hd/8mb video/dvd (dvd drive has been swapped out for a 24x cd drive). Again, the unit deviates from the above line in that it no longer contains a dvd drive, instead it has a 24x cd drive. And the memory has been doubled to 128mb. Otherwise, everything checks out correctly in the system profiler. A visual inspection of the laptop reveals a beautifully bright screen with no cracks or scratches. The left bay contains the battery (we cannot guarantee life of batteries). The right bay contains the cd drive. Side contains a pcmcia card slot. The rear of the unit contains infrared port, external monitor connection, s video connection, scsi connection, ethernet connection, audio in and out connection, power connection, built in 56k modem, two usb connection and more.
