Tim Rowledge observed:
Which is all well and good until you run out of 1's, like we sometimes used to when I was a young'un trudging to school barefoot in the snow, uphill both ways.
Ron Teitelbaum exclaimed:
You had FEET?
Eliot Miranda clarified:
yes, but there was only the one pair to share between all 17 siblings...
You guys are being silly, but when I was in the first year of the university I actualy kept a bag full of 1s. The computer was a Burroughs B6700 and students had to use punched cards to program it (this was replaced with terminals the following year). While on normal days the both the card reader/printer room and the keypunch room were deserted, on the due dates for student projects the lines were Disney-level long. To have a faster turn-around for small edits, I had previously collected a bag full of chad from the keypunch machine (the 1s), had typed a card with all characters to have a reference for the codes and had a razor blade for cutting new holes (the 0s). There was no need for tape or anything like that to keep the chad in the covered up holes as the card went through the reader: both the hole and the chad had rough borders and rubbing a fingernail on them on a smooth surface would expand them slightly.
-- Jecel p.s: the 1s and 0s in this story are probably inverted - just apply XOR 1 and it will be true
