My old boss sent me a pack of 50 blank punch cards for Christmas a few years

and such. I'd probably be more inclined to keep them as bookmarks, except I
already use old business cards for that.
But I thought it was an interesting idea and went to eBay to see what I
could get them for. My buss must have a source of his own, because the last
I looked people are trying to sell old punch cards for $100 for a pack of
50, or even $10 for just one. They're antiques, now! Yeah, here we go:
$11 Canadian for one. US$19.45 for 15. $26.69 for 40. Like that.
Here's a test question for youngsters: Why do they "boot" a computer?
Where does that term come from? I'm guessing most of them will assume it's
a sort of joke, that you have to kick a computer to get the ol' clunker
going, like "percussive maintenance" on a TV. Oops, an old-style CRT TV, I
mean, of course, which I suppose is another thing that doesn't exist any
more.

The card punch machines I used would punch each character as you typed it,
rather than buffer and punch card at the end of the line. So, you had to
type *perfectly*. A single mistake meant throw out the card. Or save it for
bookmarks and grocery lists.
I like to ask the new people I work with "Why does ISPF maintain sequence
numbers in source?" (or JCL, sysin members, etc.). Not one answers "so you
can put your punched card deck back in order when you drop it".
(They also don't know why old programs, and JCL, is all upper case.)
