Abstract
Abstract A method of copying system data at the time of updating of a main control apparatus in a system using a computer, and a copying adaptor used for this method. The method comprises replacing the control program memory of a main control apparatus, when it is updated, by an adaptor having the function of transferring and retaining system data, transferring and storing the system data stored in the system data memory of the main control apparatus to and in the adaptor, and connecting the adaptor to a new main control apparatus to transfer the system data so as to store the system data in the system data memory of the new main control apparatus.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
261 words
A method of copying system data for a computer system which comprises a main control apparatus including a control CPU, and various CPU-associated circuits inclusive of a control program memory and a system data memory, said control program memory being a separate member from other portions inclusive of said control CPU and connected to said control CPU by a connector, said method comprising the steps of: replacing the control program memory of a main control apparatus, when it is updated, by an adaptor having a program stored in its program memory for causing transferring and retaining system data from said main control apparatus, said adaptor being connected to said control CPU by said control program memory connector; transferring and storing the system data stored in said system data memory of said main control apparatus to and in said adaptor; attaching said adaptor, with said stored system data, to the program memory connector of a new main control apparatus; and enabling the control CPU in said new main control apparatus to transfer the system data from said adaptor so as to store the system data in said system data memory of said new main control apparatus, said adaptor being connected to said new main control apparatus by the control program memory connector of said new main control apparatus; and removing said adaptor from said connector after the system data has been transferred and stored in the system data memory of the new main control apparatus and reconnecting the member containing control program memory to the new main control apparatus in said connector.
Claim 2
Independent Claim
261 words
A method of copying system data for a computer system which comprises a main control apparatus including a control CPU, and various CPU-associated circuits inclusive of a control program memory and a system data memory, said control program memory being a separate member from other portions inclusive of said control CPU and connected to said control CPU by a connector, said method comprising the steps of: replacing the control program memory of a main control apparatus, when it is updated, by an adaptor having a program stored in its program memory for causing transferring and retaining system data from said main control apparatus, said adaptor being connected to said control CPU by said control program memory connector; transferring and storing the system data stored in said system data memory of said main control apparatus to and in said adaptor; attaching said adaptor, with said stored system data, to the program memory connector of a new main control apparatus; and enabling the control CPU in said new main control apparatus to transfer the system data from said adaptor so as to store the system data in said system data memory of said new main control apparatus, said adaptor being connected to said new main control apparatus by the control program memory connector of said new main control apparatus; and removing said adaptor from said connector after the system data has been transferred and stored in the system data memory of the new main control apparatus and reconnecting the member containing control program memory to the new main control apparatus in said connector.
Claim 3
Dependent Claim
42 words
The method of claim 1 including the step of using said method of claim 1 to replace a malfunctioning main control apparatus with a properly functioning new main control apparatus including the step of determining that a main control apparatus is malfunctioning.
Claim 4
Dependent Claim
178 words
In an arrangement for copying system data stored in a main control apparatus having a control CPU and various CPU associated circuits including a control program memory and a system data memory, said control program memory being a separate member and connected to said control CPU by a connector, the improvement comprising: an adaptor having: first memory means for storing system data from said system data memory; second memory means for storing a program for controlling the system data transfer between said first memory means and a system data memory; and means for connecting said adaptor in said connector for connecting said control program memory separate member to said control CPU so that said adaptor may replace said separate member; wherein copying system data to said adaptor is effected by removing said separate member from and connecting said connecting means of said adaptor to said connector; and wherein copying said system data from said adaptor to a system memory is effected by connecting connecting means of said adaptor to a connector for a control program memory separate member.
Claim 5
Dependent Claim
178 words
In an arrangement for copying system data stored in a main control apparatus having a control CPU and various CPU associated circuits including a control program memory and a system data memory, said control program memory being a separate member and connected to said control CPU by a connector, the improvement comprising: an adaptor having: first memory means for storing system data from said system data memory; second memory means for storing a program for controlling the system data transfer between said first memory means and a system data memory; and means for connecting said adaptor in said connector for connecting said control program memory separate member to said control CPU so that said adaptor may replace said separate member; wherein copying system data to said adaptor is effected by removing said separate member from and connecting said connecting means of said adaptor to said connector; and wherein copying said system data from said adaptor to a system memory is effected by connecting connecting means of said adaptor to a connector for a control program memory separate member.
Claim 6
Dependent Claim
34 words
The arrangement of claim 3 wherein said first memory means includes a RAM-type memory and said second memory means includes a ROM-type memory and wherein means are included for making said RAM-type memory non-volatile.
Claim 7
Dependent Claim
17 words
The arrangement of claim 4 wherein said means for making the RAM-type memory non-volatile includes a battery.
