A low speed punch 10 cps vers a high speed punch
50 cps could be a important cost factor. Now if you
had black paper tape one could zap out the holes
with a laser giving you a very high speed punch.
Since the punching speed does limit paper
tape to a practical limit of about 8kb was there
any really large paper tape programs? 4K focal on
a TTY was as long a program that I ever loaded from paper
tape ... 20 minutes.
Well, a good optical reader can read 400 characters per second. Correct me
if i'm wrong, but that seems like 4096 bytes takes 10.24 seconds to read
in. Assuming its not a 30 year old tape that vaporizes at that speed ;)
