Abstract

A cartridge programming system is provided for loading selected computer programs into a reprogrammable plug-in cartridge memory. A host computer controls a plurality of remote programming terminals. The terminals contain a library of programs. The consumer can select one and have it loaded into a blank cartridge. The terminal verifies the integrity of the copy and records the transaction. The host can send new programs to the terminals via dial-up telephone lines in response to the selection of a program not present in a particular terminal program library or in order to update the library of programs at each terminal and can request data on copying-transactions. Various security measures help assure accurate accounting of copies made, thereby assuring authors and their assignees that proper royalties can be billed.

Claims

1. In a system for recording computer programs in reprogrammable memories, a multiplicity of recording terminals, each recording terminal comprising:

first memory means for storing a program library comprising a multiplicity of predefined computer programs;

second memory means for retaining transaction data representing the number of times each said predefined computer program has been recorded;

command entry means coupled to said preprogrammed data processing means for selecting one of said predefined computer programs, and for initiating the recording of said selected computer program in a reprogrammable memory;

memory receptacle means for coupling a reprogrammable memory to said preprogrammed data processing means so that said selected computer program can be recorded therein; and

host communication means for coupling said first and second memory means to a host computer, said host communication means including;

means for sending said transaction data from said second memory means to said host computer so that said host computer can compile data representing the number of times each said predefined computer program has been recorded;

means for receiving selected computer programs from said host computer and for storing said selected computer programs in said first memory means of said recording terminal.

2. A recording terminal as set forth in claim 1 wherein:

said program library includes computer programs for use on a plurality of different computer models, wherein the computer programs for use on at least one of said computer models is not useable on at least one of said other computer models;

said memory receptacle means includes a plurality of distinct receptacles for coupling physically distinct types of reprogrammable memories to said preprogrammed data processing means, wherein at least one of said physically distinct types of reprogrammable memories is useable only with predefined ones of said different computer models;

said recording terminals each further including display means for displaying messages; and

said preprogrammed data processing means is programmed to perform the tasks of

displaying on said display means a list of the computer programs in said program library which are for use on a specified one of said plurality of different computer models;

in response to signals from said command entry means indicating the selection of one of said computer programs for a specified computer model,

checking for the presence in one of said memory receptacles of a reprogrammable memory of a type which is useable with said computer model, and then recording said selected computer program in said reprogrammable memory.

3. A recording terminal as set forth in claim 2 wherein:

in response to signals from said command entry means indicating the selection of one of said computer programs for a specified computer model, said preprogrammed data processing means is further programmed to perform the task of

verifying that said reprogrammable memory is ready for the storage of a computer program therein and producing a corresponding message on said display means if it is not ready.

4. A recording terminal as set forth in claim 2 wherein:

said list of computer programs displayed on said display means includes computer programs not in said program library; and

in response to signals from said command entry means indicating the selection of one of said computer programs for a specified computer model, said preprogrammed data processing means is further programmed to perform the task of

verifying that said selected computer program is in said program library, and if not, using said host communication means to establish a connection with said host computer and to initiate the process of having said host computer send said selected computer program to said recording terminal for storage in said first memory means.

5. A recording terminal as set forth in claim 1 wherein said reprogrammable memory is a memory cartridge;

and

said preprogrammed data processing means includes means for verifying that said selected computer program has been successfully recorded in said reprogrammable memory.

6. A recording terminal as set forth in claim 1 wherein:

said recording terminal includes display means for displaying messages;

said preprogrammed data processing means is programmed to respond to signals from said command entry means indicating the selection of one of said computer programs for a specified computer model by performing a sequence of steps, including the step of verifying that said reprogrammable memory is ready for the storage of a computer program therein, and producing a corresponding message on said display means if it is not ready; and

said preprogrammed data processing means includes means for verifying that said selected computer program has been successfully recorded in said reprogrammable memory.

7. In a system for recording computer programs in reprogrammable memories, a multiplicity of recording terminals, each recording terminal comprising:
