RIP AND READ: IBM’s 1403 printer printed faster and more clearly than previous devices. It used a chain of letters moving horizontally so that each hammer would hit a selected letter just as it passed by. That way, any timing error would affect only the spaces between the letters. Don Luke [left] and Frank King restored it.<
