I think I've posted this half a dozen times already but CS graduates would have needed to first pass the FE (Fundamentals of Engineering) exam before becoming an EIT (Engineer In Training) and then eventually being allowed to take the PE exam for software engineering. However the FE exam in those years included topics like thermodynamics that aren't included in a normal CS curriculum so it would have been impossible for a CS student to pass without taking courses outside of their major. So of course nearly nobody ever took the software engineering PE exam despite the explosive growth in developer jobs in that era because NCEES made it effectively impossible to even try.
