In terms of calculators, I remember when my family got our first one used exclusively for doing the books on our farm when I was about 14 years old...it replaced an adding machine. It was a big clunky Texas Instrument thing red display but ours plugged in...
We used slide rules in science classes until I graduated high school...my teachers allowed the use of slide rules but no calculators...at university I got my first calculator of my own.
My Junior year at high school saw the first computers...TRS80 I think we had 6 of them for about 750 students...
My father in-law still regularly plays his vinyl records (and he has made sure that we have retained the capability to play "records" too although we don't)...he is a vinyl nut and has the gear to play any vinyl you've got...
