Well, really the card sequence number are in 73-80.  If you have FORTRAN on your punch
cards, then line numbers are in  1-5 with a continuation character (no \ at the end of the line)
in column 6, with the FORTRAN statement starting in 7 through column 72.  And not just
IBM, either, UNIVAC / Sperry / UniSys and other also used 80 column wide cards, punched
with rectangular holes.  There were other 90-column cards that were around before, perhaps
with round holes punched.  Maybe we could adopt the really retro-necro-classic 90 
column wide standard?

I am sad that I no longer have any of my actual card decks with me any longer, though I
have a seemingly infinite supply of punch-card note cards.  Very strong and robust paper
stock, even 30 years later.
