I've heard that in the 80s, that at the same time many more people started wanting to study comp sci (due to the home computer boom) many faculty were also leaving for industry. This led to a shortage of teaching professors.
Due to this, many schools started only accepting the top tier students for their programs. If HS teacher biases were hurting women's performance in mathematics and such, this would be reflected in their lower participation in college comp sci programs
