The physical dimensions of the punched cards were
chosen to match dollar
bills, so that the processing hardware could make use of existing
subassemblies. I don't know why that particular hole to hole spacing was
chosen, but that combined with the size of the cards resulted in 80
column.
Are you sure? A punch card is a bit larger than a dollar bill.
