But, of course, the stuff comes on little rolls about 10" diameter, so unless you wanted to splice hundred of rolls together, you couldn't get it in a single piece. Hmm, let's see, a teletype would take 2 weeks to punch that (little known constant, 1 million seconds is very close to 2 weeks - In the VAX operating system, there was some system variable that was shown in units of uFortnights, being very close to one second).
