How much of this is just labour side supply/demand? If you have an all-male profession suddenly open up to women then that effectively doubles the pool of candidates. You would expect wages to go down (a lot) in that case.
As such it is more the image is programming will be women's work than a reality because the reality is there weren't many programmers.
“Systems analyst” used to be the name of our job.
Also the term "Computer" was actually an occupation (that was dominated by women) before the modern usage [2]

Economists are now finding that as more women move into a profession, the pay goes down. Similarly, when computer programming moved from a female dominated profession (early days) to male dominated (now) the pay went up. Medical fields that have higher proportions of women have lower pay. Along these lines, as college skews more female (college grads are like 60/40 female/male now) the "college grad" professions are having a declining wage premium compared to non college grad jobs.
