They were input laboriously by hand either on punched cards, with each card holding up to eighty characters or one line of text (uppercase letters only), or on paper tape, where lower-case letters were perhaps possible but which could not be read in any way at all by a human being. Father Busa has stories of truckloads of punched cards being transported from one center to another in Italy. All computing was carried out as batch processing, where the user could not see the results at all until printout appeared when the job had run.
