They had one of those, adapted to read the output of a bed of photocells installed in a Harris sheet fed press on the SUI campus in the later 1950's. I saw it running once, grading the test score sheets from the Iowa Tests that were being used in lieu of the high price per seat S-B IQ test in the Iowa schools. It was IIRC a somewhat difficult test when they threw it at me in the 7th grade a decade earlier, they claimed the test score were interchangeable with the S-B scores, but I somehow managed a 147 on it at the time.
