It is? How? I don't know. We recorded our entries, which were transcribed by the folks in the secretarial pool (sorry, don't know the PC term for that), one of whom told me that their word processors produced the typing that way. Maybe she was pulling my leg, but I seem to recall visiting the pool to observe this wonder. Seems as though there was, in place of where the keys on a typewriter would have been, a central ball that turned according to whatever character had been hit on the keyboard. Possibly this was some other type of machine, but they called them word processors. This was in the late 70's -- early '80's.
