ABSTRACT:
An interface for converting standard computer character code, in either serial or parallel form, into a sequence of simulated acoustic wave pattern signals. These wave pattern signals are then applied to an acoustic bar operated typewriter, like the typewriter sold under the mark "Typetronic" by the SCM Corporation, duplicating the acoustic wave fronts that are generated by the keyboard. Thus the typewriter is conformed to operate as a data processing printer without any reduction in the functions thereof.
