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.

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...

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.
