I also seem to
recall that Univac or some other computer manufacturer
actually used a 90 (?) column card for even better packing density.
I'll leave that improved calculation to someone who actually remembers
how many columns those cards were blessed with.
Sure, there are many other types of cards. Round holes, different shapes,
read by a matrix of push buttons, etc.
