The image email (5 level PBM) is moderated by greenkeys but may have made it to you directly.

I do have 2 creed teleprinters, model 75s though. The interface is a massive daunting connector, been meaning to ask if anyone has interfaced one.


Yes, I have interfaced a 75. The interface isn't hard, the thing with the 75 is that the keyboard is mechanically connected to the print mechanism.
The manuals are here:-

I have a 75ERP so with a punch, a 7B so KSR some 6S readers and a 75. I believe Turing brought a Creed 7B to Manchester when he came which could be the reason many UK computers used paper tape rather than cards.

If the image does not work let me know, that is my friends software. I could also ship you my BRPE which is contemporaneous to punch tape and demo on campus for a bit if of interest, but it is an 8 level punch not 5 level. It is in a hard case ready for shipping and has an mcu attached to punch sample tape on demand.

I could punch a tape but getting it to you

Our computer science department here at the U of Iowa is trying to create wall art celebrating great works in computer science.  We've decided to do it with the leading part of each historic paper rendered in the digital recording medium of the time when that paper was first presented.

One paper we want is Alan Turing's 1936 paper on computable numbers.  He was British, so if he were to send this paper to someone in digital form, he'd likely have used a Creed Model 7
page printer, paired with an appropriate tape punch.

What we need is the punched tape.  If someone has a punch and the wherewithal to convert ASCII to ITA2, I can send you the text we want.
