I do remember cards with no corner cut, and also with pointy corners rather than the usual

Some devices would feed 12 edge first. I vaguely remember IBM reader/punch units where
one went 9-edge first and the other 12-edge first.
Then of course some card devices feed the narrow edge (1 column) first rather than the top
or bottom row. CDC had a reader that worked column-wise and a punch that worked row-wise,
so the interface logic for the punch needed a transpose operation while the reader
doesn't -- given that both would transfer card data as a word per column. But
Electrologica used the same hardware without the transpose logic in the controller, so the
software would see columns from the reader but would have to construct rows to send to the
punch.

Didn't know that one. I do know:
He died at the console
of hunger and thirst
next day he was buried
face down, nine edge first
Well, I am definitely not the first one to say it.
Face down: since card readers deal off the bottom of the deck, that puts the first card
first. for burial, I can moon the world, or they can kiss my ass.
9 edge first puts the cut corner on the outside, where it is visible, to notice if a card
is turned. I have seen corner cut on either left OR right upper corner. I don't
recall seeing any with both corners cut.
