Plural typewriters coupled for simultaneous operation (e.g., "master-slave" relationship):
(under subclass 70) Subject matter wherein a first typewriter, while it is operating to type on a record-medium*, produces signals. These signals (i.e., signals from inside the first typewriter, but from outside a second typewriter) are used to govern the operation of the second typewriter concurrently with the operation of the first typewriter, whereby corresponding character* symbols are typed onto a second record-medium at the same time that character symbols are typed onto the first record-medium by operation of the key-board* of the first typewriter.
