Having thus described the invention, what it is desired to claim and thereby protect by Letters Patent is:

1. In an apparatus having a keyboard for generating keystroke data and keystroke control signals, and a data processor for receiving said keystroke data and keystroke control signals, said keyboard having a keyboard connector with a plurality of contacts, and said data processor having a data processor connector with a plurality of contacts, wherein said keyboard connector and said data processor connector are normally interconnected for conducting keystroke data and control signals between the keyboard and the data processor, an improvement comprising:

a spelling check module having first and second connectors interposed between said keyboard connector and said data processor connector, said first connector being connected to said keyboard connector, and said second connector being connected to said data processor connector.

2. A spelling check module in accordance with claim 1 further comprising:

a plurality of connecting means for connecting individual corresponding contacts of said first and second connectors within said module;

register means connected to the connector contacts of said keyboard connector which carry the keystroke data generated by said keyboard, said register means including means for accumulating successive alpha keystroke data;

dictionary means containing a plurality of codes in digital form corresponding to correctly spelled words;

control means responsive to said register means and said plurality of connecting means for detecting a typed word, and responsive to said dictionary means for comparing said detected typed word to the digitally coded contents of said dictionary means and for providing a first output indication corresponding to whether said dictionary means does not contain a digital code corresponding to said detected typed word; and

indicator means responsive to said first output indication from said control means for indicating that said detected typed word is misspelled.

3. A spelling check module in accordance with claim 2 further comprising:

means responsive to a first simultaneous combination of two non-printing, non-control keystrokes for deactivating said spelling check module; and

means responsive to a second simultaneous combination of two non-printing, non-control keystrokes for reactivating said spelling check module.

4. A spelling check module in accordance with claim 3, wherein said keyboard further includes user definable keys on the left and the right side of the keyboard face, wherein said first and second combination of non-printing, non-control keystrokes each comprises the combination of said left and right user definable keys.

5. A spelling check module in accordance with claim 2 further comprising:

personal dictionary memory means for storing and retrieving data;

second control means responsive to said register means for storing data in said personal dictionary means representing a correct spelling of a word in said register means;

means responsive to said detected typed word in said register means for comparing said detected typed word to said correct spelling data stored in said personal dictionary memory means and for providing a second output indication corresponding to whether said personal dictionary does not contain a digital code corresponding to said detected typed word; and

indicator means responsive to said second output indication from said control means for indicating that said detected typed word is misspelled.

6. A spelling check module in accordance with claim 5 further comprising:

means responsive to simultaneous combination of two non-printing, non-controlling keystrokes for storing said correct spelling of said detected typed word in said personal dictionary memory means.

7. A spelling check module in accordance with claim 6,

wherein said simultaneous combination of two non-printing, non-control keystrokes comprises one of said user definable keys and a shift key.

8. A spelling check module in accordance with claim 1 further comprising:

control means connected to said plurality of contacts of said keyboard connector for transferring received signals to said plurality of contacts of said data processor connector;

said control means also connected to said plurality of contacts of said data processor connector for transferring received signals to said plurality of contacts of said keyboard connector;

said control means further including register means connected to said plurality of conductors of said keyboard connector, wherein said p
