Miniature digital assistant having enhanced host communication

A combination computer system comprising:

• a host computer having a host CPU, a host memory and a docking bay having a host portion of a parallel bus connector coupled by a host interface parallel bus to the host CPU, the signal lines including address lines, data lines, and control signal lines, control signals including read/write and at least one memory control signal;
• and
• a satellite digital assistant having an enclosure with a satellite portion of the parallel bus connector in one surface, connected by an extension of the host interface parallel bus to a satellite CPU, the satellite digital assistant having also a satellite memory connected to the satellite CPU and an input-output apparatus on a surface of the enclosure;
• wherein, with the satellite digital assistant docked in the docking bay with the host portion and the satellite portion of the bus connector engaged, digital communication passes between the host computer and the satellite digital assistant.

A digital assistant module, comprising:

• an enclosure for enclosing and supporting internal elements;
• a local CPU within the enclosure for managing functions of the digital assistant module;
• a local memory connected to the local CPU for storing data and executable routines;
• a power supply within the enclosure connected to functional elements of the digital assistant module;
• a touchscreen combination input/display operable by the local CPU and implemented on a surface of the enclosure;
• and
• a host interface comprising a host interface bus having address lines, data lines, and control signal lines, control signals including read/write and at least one memory control signal, the host interface 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 for connecting the local CPU to a compatible bus structure of a host computer having a host CPU and a host memory;
• wherein, upon connection to a compatible host computer through the host interface bus, digital communication occurs between the host computer and the digital assistant module, and synchronization of commonly-named files is accomplished.
