Solving their own problems and not the worlds.

Do you forget that 6 computers were going to satisfy all the computational needs of the world?

And no one has yet mentioned IBM's EBCDIC - Extended Binary Coded Decimal Interchange Code which came out in 1964 or so. These came in "national" flavors.

Hey, 2nd generation computers used 6-bit codes for characters (related to punch card codes) - uppercase letters, numbers, and a few punctuation marks. [link|http://www.cs.uiowa.edu/~jones/cards/codes.html|Link].

It's evolution, guys!
