> It's interesting to me that no one had a cassette recorder in class.

Not too surprising given that a cassette tape in the 70's cost several dollars (equivalent to maybe $20 today). It was so expensive it simply didn't occur to people to record such things.

It's like photos. The cheapest 35mm photo cost a buck an image, and this was for slides, not prints. It's why photos of my college career are nearly non-existent. And movie film - forget about it.
