I'll avoid dating myself, but let's just say I took typing class around the same time you did. Classroom had 20 IBM Selectrics. I was the only male in the class and probably the only student who wasn't in the Business/Accounting track (I was in College Prep and they couldn't figure out why I would take the class since professionals at the time had a secretary type all their correspondence). I foresaw that it was going to be a valuable skill because I was also in my school's first computer science class. None of the guys, and they were all guys, in my comp sci class could type, they were all hunt-and-peck.

So I learned the traditional way with an egg timer and a spiral-bound exercise book on a stand. Curled fingers. I still type this way, and I can still do about 170+ wpm depending on how many cups of coffee I've had.

Later, this really helped me when I got an IBM Model F keyboard or Sun UNIX keyboard and when I would fly around Vi like a keyboard assassin it would amaze my colleagues. My current keyboard is a mechanical Ducky with Cherry MX Brown switches: https://www.duckychannel.com.tw/en/Ducky-One-Golden-grey-TKL
