I also took typing class in probably 1976 or ‘77. I do not, however, recall a noticeable imbalance of female vs male students. And our teacher was Mr. Fred Rodgers.
Ours were non-electric typewriters of various vintage. My parents had reason to do a lot of typing, so we were privileged to have an electric at home. That electric still had manual carriage return, though.
But you were all special types, each and every one of you
Two years of typing class it and was the most useful class I had in that high school - which was otherwise like the school in "Welcome Back Kotter"
I was kicked out of my school district (concerning an assault on a certain gym coach) and enrolled at Rainier Beach High (notable for having the armed black panthers take over the school). Coming in mid-session I didn’t have a lot of choice picking classes to attend. So I signed up for typing class.
I figured that the worst that might happen was to flunk the course and the best was that I would be the only guy in a classroom full of girls.
It turned out to be a solid win win win - I passed the course, I graduated, and I hooked up with a pretty girl.
I learned how to type too ;’}
