Oh, in answer to your questions... Punch cards. Did a lot of programing in FORTRAN. You handed your pile of punch cards in through a little window into the computer room. . . and then a week later, they handed your pile back with a large printout (if there were errors in your punch card program) or a small print out (if everything worked!). If the pile of paper was large, you went to work debugging the program to figure out what you did wrong to result in the printer vomitting through a case of green lined paper.
The college still had some paper tape fed stuff too... Real antiques.
I wondered if it was FORTRAN... or COBOL.
My first language was FORTRAN (in college) and I actually programmed it with punch cards. Lol. I sympathize!!!
I still have my four inch thick stack of punch cards. That reminds me that I need to find them and show them to my son. Anyway, couple of years later, I noticed that the punch card machines with VT100 terminals. And now VT100s are long since a thing of the past.
Hey, since you have been around, what systems did you use? DEC PDPxx? I worked at DEC in Data Storage.
