I was looking
here:
http://bitsavers.informatik.uni-stuttgart.de/pdf/ibm/360/
fe/2020/Z33-1021-0_2020_Processing_Unit_FETOM_May68.pdf
(pdf) pages 45, 46 describe the ALU
I note that the cover page says: "(Machines with serial no. 50,000 and
above)."
Perhaps the ALU is only present on late model machines?
