It's the ECMA standard for paper tape.

OBA! I'm crazy for creating a paper reader/perfurator! :D This is an old
dream of mine, although I have no specific computers who use it, nor any
specimen of perfored tape around. But I find it to be just beautiful :)

The reader is relatively easy to make at home, at least if you are happy with a
photoelectric one. If you trigger off the feed holes, you don't need a sprocket
drive, a capstan and pnch roller is fine. This is the sort of thing you can make
in a good home workshop.
The punch is a lot harder. Making the punch pins and die block, and then
correctly grinding and hardening the former is not going to be easy.
Mechanically the rest may not look too hard (the Facit 4070 used a set
of rotary solenoids and linkages, one per pin), but it is still a major
project.

I had a dream of creating a paper tape with a program I wrote on it for the
Pegasus computer at the Science Museum. If they ever turn it on again, or
another one crops up, I might not have any excuses left...

Perhaps not quite the same, but when I bring my Teletype Model 33, connected to a
DECSYSTEM-20 emulation, to DEC Legacy in April you can save a program on paper tape if you
like.

Some time in the future I would like to build an FPGA emulation of the Pegasus, complete
with console switches, tape readers, tape punches and Creed Teleprinter. I have some of
the parts including a Creed Teleprinter and Creed Paper Tape reader, Post Office Switches
for the console. I can't find a Creed 25 high speed punch so I will have to improvise
and use one of my other punches.......
... if its ever completed I would be glad to run your program....

There is a Pegasus emulator here:-
http://sw.ccs.bcs.org/CCs/simulate.htm
it can be configured to output the tape output to the printer port, so whilst you
can't run a program on a real Pegasus you should be able to get paper tape out if you
had a paper tape punch.
I was hoping to be able to feed the tape from this program into the original Creed 6S
paper tape reader, and hence print it on the Creed printer from the Pegasus at MOSI
Manchester.
Sadly, MOSI have decided they want to re-use the gallery the Pegasus is displayed on so
the project has been suspended. I don't expect it to restart. I had got as far as
printing from paper tape.

Couldn't you make the punch these days with a row of lasers? or maybe a single laser
that sweeps across the tape laterally?
Bonus because there wouldn't be any of that messy chad left. It'd just be up in
smoke, so to speak :-)
