Combination personal data assistant and personal computing device with master slave input output
First Claim
1. A mobile computing system comprising:
- a personal computer architecture system (PC);
a personal digital assistant architecture system (PDA);
a communication device coupled to the PC by a first bus and coupled to the PDA by a second bus; and
a switch coupled to the PC by a third bus and coupled to the PDA by the second bus, such that control of the mobile computing system is isolated to the PDA when the switch is in a first state and control of the mobile computing system is taken by the PC when the switch is in a second state, the communication device being continuously coupled to the PC and the PDA.

Abstract
In order to provide continuous communication ability in a computer architecture that integrates a computer (PC) architecture system and a personal digital assistant (PDA) architecture system, a common communication device is provided. Independent access is made available to the communication device to either the PC or the PDA depending on which system is in control. A switch isolates either the PC or PDA to control of the communication device and other common peripherals. The PDA can be a slave device to the PC, with both systems synchronized with one another and able to exchange information and data. Because the PDA consumes much less power than the PC, the PDA can remain active while the PC is shut off. Because the PDA has the ability to communicate the computer continues to receive and transmit messages and information.
