Me too: IBM 360 Assembler. I only took it because it was the only remaining computer class offered. Submitting card decks and getting back core dumps the next day... not the most fun process.I used punchcards in my year 12 computer science class, on the mainframe, doing batch processing. I also still have a manual hand-punch that works like a dymo label machine. Dial up the letter, clunk. Next letter, clunk...
However... I freakin' *loved* the card punch. Watching the card go zooming through the machine was the best. Satisfying clunk-clunk while taping. *Loved* it.
Our card punch was in the same room with the donated minicomputer and the four (or so) Teletype 33s, which were perpetually thundering CLUNK CLUNK CLUNK CLUNK in the background.
Computer class was a high-decibel experience back then. Good times.
