Module for extending the functions of an electronic data processing machine

A module for extending the functionality of an electronic device comprising:

• a write-read unit having a compact housing, and in said housing there is at least one drive for rotating storage media and at lease one storage media receptor portion for receiving a plugable, removable, encapsulated flat card provided with highly-integrated electronic circuits for data processing and storage independent of a central processing unit (CPU) of said electronic device;
• said housing accommodates further a control electronics for joint or separate selection of the storage media and, at the same time, establishing a direct intelligent connection independent of the central processing unit (CPU) between the at least one drive for rotating storage media and said at least one receptor portion for receiving a plugable, removable, encapsulated flat card such that the at least one drive for rotating storage media and the at least one receptor portion can communicate independently of the central processing unit;
• and
• an interface module for establishing a connection between the control electronics and the central processing unit (CPU) of said electronic device.
