I understand. I was the same, and went to the café for a couple of beers. :-)

But this mirrored the 25x80 column 3270s from the 60s which mirrored cards which were 80 columns which owe their existence to Hollerith adapting the Jacquard looms from the 19th century which automated the looms of the 18th century... :)

I did know about that story (this one: ) but there seems to be
a lot of controversy around it...

And I always find I need to cut a lot of material to fit the time
slot, in any case.
