It's unfortunate that the minute you walk out the door with your new iBook, you must start thinking of ways to protect it from theft. Let's face it: the iBook, with its rich blue or orange skin, is attractive not only to you but also to those who'd like to make your iBook their own.

Unified Motherboard Architecture

The clamshell iBook was the first Mac based on the new Unified Motherboard Architecture (UMA). The logicboard sported new Apple specific ASICs which supported the new standards (USB, FireWire, Ethernet 100mbit, Ultra DMA).

The integration of the controller chips "UniNorth" and "KeyLargo" shows the figure on the Japanese website Medicalmac, the link is a Google translation - or the Apple Developer Notes

The scalability of UMA systems makes it possible that future models can be built on same architecture, reducing development and production costs. For example: the AGP graphics can be accessed with 2x or 4x speed, The bus speed is adjustable from 66MHZ to more than 100MHZ - which is particularly useful for Overclockers.

It is a pity that the Clamshell series ended in 2001, so many possible features were not integrated. The logic board had e.g. still had free space for RAM banks and other interfaces.
