What machine was it that had about 12,000 12AU7 vacuum tubes in it for
logic? 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.
