Forwarding to a pen pal who was involved in electronics already before
the transistor was invented.
What? How aged are you folks? I'm from 1966 and when I started with
computers, I already used 5 ¼ floppy disks.
Am I a youngster?
I'm used to analog audio and video engineering, analog photography and
computers with 5 ¼ floppy disks. I just started programming assembly
without a macro assembler, but after a relatively short time even a
macro assembler was available.
"Card reader" nowadays is for something else.
I used a hole puncher to write on both sides of a single sided 5 ¼
floppy disk, but have never seen a punch card in reality.
