Same. My high school had a "computer lab" which had a teletype with a paper tape punch that communicated over a modem to a local community college. Definitely not the norm at the time for a high school.

Same, in junior high school around 1980 (we had some DECWriters and a Hazeltine terminal connected to an HP2000 somewhere). Kids played HP BASIC Star Trek:

I remember my first program was a slot machine- so I learned about generating random integers within a desired range.
