At least some of the angles: "EBCDIC lost," "Keypunches had already abandoned bit-pairing http://www.righto.com/2017/12/repairing-1960s-era-ibm-keypunch.html …," "Computer industry people didn't anticipate interactive computing"

Ah, got it. I was thinking on a higher level. (BTW aren’t laptop numeric-keypad-on-alpha section inspired by key punches?) I have that article queued up, but haven’t read it yet!

I think more likely independent reinvention, if only because the keypunch ones put 123 on the top instead of 789?

whoa, this made me look up and notice that keypunches use telephone layout instead of cash register layout! wonder why

Probably originally to follow the physical order of the punches on the card, since there was a direct mechanical linkage on early ones?

this article makes me think the numpad keys could have gone either way: http://www.righto.com/2017/12/repairing-1960s-era-ibm-keypunch.html … -- i wonder if maybe the overlap between punchcard enthusiasts and adding machine operators was really low

Yes but that was after years of development. In early punches, little stood between the keyboard and the card. (Note the physical stagger of the rows even.)pic.twitter.com/WGU4rHlEQt

Quiz: what was the only *computer* keyboard in history that had the same keypad layout?

Nope, although that keyboard is its own world of wonder.
