I agree. Both the TRS-80 (which was specifically mentioned in the audio version of the article) and the Apple II were released in 1977.

>By 1982, an estimated 621,000 home computers were in American households, at an average sales price of US$530.

In a country of 220 million people. If we assume about 4 people could access a single computer, then 1,1% of population had access.

So it seems commercials of Apple II and TRS-80 was the thing that compelled women to stay out of the field. Or alternatively getting your hands on dads TRS-80 was incredibly compelling experience to almost every boy out there.

High school students aren't representative of the general population. Schools had computers, so all of them had access.
