The first “computer” I had was from Radio Shack. to “program” it you had to use patch wires to connect switches, relays, and lights. Of course the switches were the “input” and lights the “output”.
My mother was a punch card operator. Her version of the “internet” was putting her cards in a shoe-box and mailing them to the west coast office.
SCIENCE SCOUTS 
Should punching up a control card for a keypunch, or line printer tape loop count? (especially if the printer tape did more than 1h1)
There should be a special version if you used punch cards on a machine without ink.
that’s how I learned to program FORTRAN
before that I use a teletype and programmed in BASIC
Learned FORTRAN & COBOL this way…and got first case of carpal tunnel that my orthopedic surgeon had ever seen…Good Times!
Learned fortran this way on a Cyber 74.
Also learned to keep the damn lid on the damn box.
I last did that in 1980 but I still have a few punch cards around the house that can be used as note cards
Does paper tape qualify?
