Porn didn’t show up until about ten years later. Back in 1972 it was more like a picture made on the line printer or teletype with characters. There was one of an orangutan, and one of, if I recall correctly, “Pam” who was probably a student somewhere. It was tame enough to show to your grandmother.
Well. Porn has made a lot of progress since Pam. /s
I remember Pam. Still have it in a box somewhere.
I have seen some pretty “untame” ones, and very detailed at that. There were some operators in some places who had a lot of spare time for sure.
