I suppose it would be mostly practical skills, cooking, fixing things. Usually had to be done by people themselves.
Maybe also mental things like navigating (with or without paper map) and remembering their daily and weekly agendas.
What other things would be a big difference with the people today?
Pulse dialing (rotary phones)

This is the origin of “phreaking”. Tapping out the pulses (on the ‘hang up button’) on a rotary public payphone to make free calls.
Oh how sweet was our youth…
