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