All,
Thank you for your generous donations to the STEM program I'm working
on. I have a question or two about the punch cards I've received.
Some of the cards have printing on one side, and are "dog eared" or
have the angled corner on one end.
Other cards have the printing reversed; the dog-ear corner is on the
other end of the card when I'm looking at the printing.
If those cards with the reversed "cut corner" or "dogear" were used
in
the same machine as the first set of cards, they'd be read
"backwards." ... so why the two different formats?
