We had one of those in High School Journalism class in the late sixties. It was used to create columns of text for layouts. It allowed the students to create the photo ready layouts instead of giving all the text to the printer for layouts. It was very tough to use and only a couple of students were allowed to use it because the machine was so expensive. You had to know how many parts of a full space every letter used and then you had to figure out how to get each line of text to fit proportionally in each line. I can't imagine why you would want that in an office situation to type up government documents. It adds nothing and is hard to use.
Great input.
Dear Casloy,
Regarding your experience with the IBM Selectric Composer: did it kern? If so, how was that accomplished?
Thanks,
