Personal computer system having a docking bay and a hand-held portable computer adapted to dock in the docking bay by a full-service parallel bus
First Claim
1. A personal digital assistant system, comprising:
- a personal digital assistant module having an enclosure, a local CPU within the enclosure for performing digital operations, a memory connected to the local CPU by a memory bus, a power supply coupled to power-using elements, a display on a surface of the enclosure, input apparatus connected to the local CPU for providing commands and data, and a host interface system including a host interface parallel bus connected to the local CPU and to a first portion of a host interface connector at a surface of the enclosure, the host interface bus including address lines, data lines, and control signal lines, the control signal lines including read/write control signals and at least one memory control signal; and
a modular computer having a plurality of enclosed module bays configured in a common plane and opening to at least one edge of the modular computer, the modular computer having an internal bus compatible in structure and protocol with the host interface bus, with at least one module bay adapted with a bus connector matable to the host interface connector to dock the personal digital assistant module and establish digital communication between the personal digital assistant module over the host interface bus.

Abstract
A personal digital assistant module with a local CPU, memory, and I/O interface has a host interface comprising a bus connected to the local CPU and a connector at a surface of the personal digital assistant for interfacing to a bus connector of a host general-purpose computer, providing direct bus communication between the personal digital assistant and the host general-purpose computer. In an embodiment, the personal digital assistant also stores a security code. The personal digital assistant according to the invention forms a host/satellite combination with a host computer having a docking bay, wherein upon docking a docking protocol controls access by the host to memory of the personal digital assistant based on one or more passwords provided by a user to the host. In another embodiment the personal digital assistant also has an expansion port connected to the local CPU, and expansion peripheral devices may be connected and operated through the expansion port.
