of the envelope calculation comes to approximately
4 million miles of paper tape.
I think you're out by a factor of 10.... 267*10^9 bytes, divide by 10 as
there
are
10 bytes to the inch on paper tape, and convert
to miles. I get just
over 400,000
miles.
Agreed, I measured a piece of paper tape I have here and got a figure of
0.9 inches per 10 bytes, so clearly just a bit of finger trouble somewhere
in my calculation. Still, almost enough for a round trip to the moon.

My rule of thumb is that a full reel of 1"
paper tape is 100k bytes So
10 for a
megabyte
10000 for a gigabyte
2,670,000 for all of bitsavers. Perhaps nearer 3 million as it's an
approximation....
