Abstract
Abstract A computer system includes a processor/memory/disk module which is selectively mated with any one of a number of associated computer base units, such as a portable PC base unit and a desktop PC base unit. The processor/memory/disk module incorporates essential elements, including a processor, a disk and a memory, of the components required for operation of a computer. The processor/memory/disk module is readily removable from a base unit so as selectively to be coupled to any desired base unit for operation of that base unit, or to be removed and put away for security purposes.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
92 words
A data processing system, comprising: a first data processing base unit included in a first computer designed for portable use and having a receptacle for receiving a data processing module; a second data processing base unit included in a second computer designed for stationary use and having a receptacle for receiving said data processing module; and a data processing module which can be placed in the receptacle of either the first or the second computer and operatively engaged with the base unit of that computer to provide an operable data processing device.
Claim 2
Dependent Claim
92 words
A data processing system, comprising: a first data processing base unit included in a first computer designed for portable use and having a receptacle for receiving a data processing module; a second data processing base unit included in a second computer designed for stationary use and having a receptacle for receiving said data processing module; and a data processing module which can be placed in the receptacle of either the first or the second computer and operatively engaged with the base unit of that computer to provide an operable data processing device.
Claim 3
Dependent Claim
44 words
The system of claim 1, in which the base unit of each computer includes a keyboard controller, a floppy disk controller, an interface for connection to the data processing module and a bus coupling said keyboard controller, said floppy disk controller and said interface.
Claim 4
Dependent Claim
26 words
The system of claim 2, in which said base unit of each computer also includes an I/O controller and an LCD/CRT controller coupled to said bus.
Claim 5
Dependent Claim
17 words
The system of claim 1, in which said data processing module includes a processor and a memory.
Claim 6
Dependent Claim
47 words
The system of claim 1, in which said data processing module includes a processor, a memory, a controller, a hard disk unit, an interface for connection to a base unit and a bus coupling said processor, said memory, said controller, said hard disk unit and said interface.
Claim 7
Dependent Claim
14 words
The system of claim 1, in which the first computer comprises a portable PC.
Claim 8
Dependent Claim
14 words
The system of claim 1, in which the second computer comprises a desktop PC.
Claim 9
Independent Claim
123 words
A method for supplying data processing capability selectively to different types of data processing devices using a common module, comprising the following steps: (a) providing a first type of data processor base unit having some, but not all, of the functions necessary to perform data processing operations; (b) providing a second type of data processor base unit having some, but not all, of the functions necessary to perform data processing operations; (c) providing a detachable data processing module having the remaining functions necessary to enable either the first or second type of data processor base unit to perform data processing operations; and (d) selectively coupling the detachable data processing module to either the first or the second type of data processor base unit.
Claim 10
Independent Claim
123 words
A method for supplying data processing capability selectively to different types of data processing devices using a common module, comprising the following steps: (a) providing a first type of data processor base unit having some, but not all, of the functions necessary to perform data processing operations; (b) providing a second type of data processor base unit having some, but not all, of the functions necessary to perform data processing operations; (c) providing a detachable data processing module having the remaining functions necessary to enable either the first or second type of data processor base unit to perform data processing operations; and (d) selectively coupling the detachable data processing module to either the first or the second type of data processor base unit.
Claim 11
Dependent Claim
17 words
The method of claim 8, in which the first type of data processor is a portable PC.
Claim 12
Dependent Claim
17 words
The method of claim 8, in which the first type of data processor is a desktop PC.
Claim 13
Dependent Claim
28 words
The method of claim 8, in which the first type of data processor is a portable PC and the second type of data processor is a desktop PC.
Claim 14
Dependent Claim
104 words
The method of claim 8, in which at least one of the first and second types of data processing base units comprises a keyboard controller, a floppy disk controller, an I/O controller, an LCD/CRT controller, an interface and a bus coupling these elements, in which the detachable data processing module comprises a processor, a memory, a controller, a hard disk unit, an interface and a bus coupling these elements, and in which the step of selective coupling comprises coupling the two interfaces to provide a data processing system which comprises a coupled keyboard controller, floppy disk controller, processor, memory, controller and hard disk unit.
