Always tricky and holding your breath for a minute or so when loading them to the computer.

In the old times we used in our factory punched paper tape for loading cam data in a Fanuc wire eroding machine. Like the one in this video :

Holes in tape are always rounds because making them square would lead to a Square Holes In Tape acronym.
Some history : https://tangiblemediacollection.com/holes.html
By the way, it was a discovery when one could double the data volume on a floppy disk by punching a second square notch in the disk cover. I still have my blue puncher. Nice days then to do crazy things. On the computer club, one had written a program to made music with the electric coil in the commodore 1541 disk drive : unscrew the lid and listening with the ear near the coil. The 1541 had a little memory, one could load a program in the drive so that one could copy floppies just by connecting two 1541 drives. Original in the one, empty floppy in the other, close both locks and the copy was made. Good old days with poke_ing a lot in the memory of the commodore computer.
