The DSI punches punch their own sprocket holes. Funny,
I don't remember prepunched tape. Wouldn't that be
punched tape prepunched with NULL's (ha ha).
It is a know fact that Santa's Elves will pre-punch your
paper tape for you on their days off. You have a choice
of white,red,or green paper tape.
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.
