Speaking of IBM...what'd be the maximum storage capacity of a punched card?   I was thinking of TCP/IP over paper tape last night...

I sense an april 1 RFC here...   :-)

Classic 80 column punched card: 120 bytes if punched in unrestricted "column binary", 80 byte if punched in extended EBCDIC code (as on the IBM 360 green card) where only one of rows 1-7 is punched per column.
