Apple iBook ClamshellThe iBook G3/300 (Original/Clamshell), codenamed P1, features a 300 MHz PowerPC 750 (G3) processor, 32 MB or 64 MB of RAM, a 3.2 GB or 6.0 GB hard drive, and 2X AGP ATI Rage Mobility graphics with 4 MB of VRAM packed into a sleek handle-equipped "blueberry" or "tangerine" case with a 12.1" TFT active matrix display (800x600 native resolution).

Following in the footsteps of the iMac models, the iBook was introduced as a low-cost portable Mac for the consumer market -- and likewise lacked Firewire ports, video out, and even a microphone. However, the iBook did herald the introduction of AGP-based graphics on the Mac as well as the innovative new optional "AirPort" wireless networking card. Later to become commonplace, "AirPort" made it possible to connect multiple iBook systems wirelessly to the Internet when paired with an AirPort base station (or other wireless system).

There are two slightly different versions of the iBook G3/300 (Original/Clamshell). The original models introduced on July 21, 1999 shipped with 32 MB of RAM and 3.2 GB hard drives, and on February 21, 2000 -- to correspond with the introduction of the iBook Special Edition -- these models began shipping with 64 MB of RAM and 6.0 GB hard drives.
