I couldn't take CS classes at my high school - I graduated in '98 and high school level comp sci wasn't even a thing yet except at specialty schools. I went to high school in suburban Pittsburgh. I graduated in 1991. I took my first "CS" class in 7th or 8th grade. We're talking mid-80s. It was a BASIC programming course on a
TRS-80 Model 2.
Granted, I think it's a bit heavy handed to call it computer science but we did learn some BASIC. I already had a VIC-20 at home so it wasn't anything new to me aside from having a teacher to ask questions to instead of just learning from the manual that came with my VIC.
When I was in 10th grade we had another BASIC class that was pretty much the same material but didn't go over as much of the fundamentals as the first one. In 11th grade I had a Pascal course. There were no further programming courses available at the time and I've never heard of AP CS high school courses until I read about it here or on Facebook in the past few weeks. I had a couple nephews who went to the same school I went to. One had graduated and one is a senior this year and by their accounts it seems that programming is no longer offered from what they've told me and one of them would have been likely to take such a course if offered.
To touch back on the question of girls and minorities, I only recall there ever being one girl in my high school level courses and she dropped it early on. There was one minority student and he kept on it through both courses and went on to be a CS major and is still working in the field, AFAIK.
