On December 4, 1964, IBM announced four microfilm products -- two unique in the microfilm industry -- that gave the company's line of Micro-Processing equipment a new systems capability for automated information handling. The machine operator at left inspects the input side of the Micro-Copier/Reproducer -- a unit that produced both punched holes and microfilm images from a punched card with a frame of microfilm to another Micro-Processing card. To the left of the woman is the console-style diazo copier -- the only diazo film copier in its price range that in one step copied images from roll microfilm to punched cards as well as from card to card. IBM's Micro-Processing system was used with punched card accounting equipment such as the interpreter (extreme left) and sorter (center). Next to the sorter is IBM's copier for thermal film, which was developed by heat and light rather than chemicals. The key punch operator at extreme right scans the Micro-Viewer with roll film attachment to obtain descriptive data to be punched onto a master aperture card. The Micro-Processing System combined the space saving method of storing documents with the advantages of processing and retrieving data on punched cards.
