[apologies if this is a dup, but I didn't see it coming back in any of
the cctalk digests]
Greetings CC-Talk,
? I've been working on a low-budget project to help to introduce
students to history of computing through material we have from MIT's
1950's Whirlwind project.? The activity would have more of a hands-on
feel if we could use actual paper tape.
? A simple reader is easy enough, but a punch is a bit harder.? We
don't need anything "authentic", or fast, or high performance, just
something fairly reliable.
?? If anyone can suggest where to find such a machine, could you let me
know?? Fanuc PPR, GNT 4601/4604, and the DSI NC-2400 have been cited as
possible candidates, but I don't see anything that looks like a good
match on ebay.
? Thanks!

If you can find on a Teletype ASR33 is the perfect example of a
reader/punch and a hard copy terminal all at the same time.
If you find 2, please let me know :)

Do you mean a punch as a computer peripheral, or a keyboard operated tape punch? For the
former, the ones you mentioned are obvious choices; BRPE is another. Also the DEC paper
tape reader/punch (PC01 or some such number).
For keyboard operated, there's Teletype, Flexowriter, Creed, Siemens, depending on
where you're located. ASR33 is a common 8-bit punching terminal. Older models that
use 5-level tape ("Baudot") may also be around, and those could certainly serve
for 1950s era machines that may well have actually used those. I don't know what
Whirlwind used, but I know some other 1950s machines that used 5 bit tape for their I/O.
Electrologica X1 is an example.

If anybody actually wants to build one I have the important part, motor
driven with solenoid operated cam driven punches; would only need a
suitable interface and maybe a cabinet.
Don't know if it would be worth while with today's shipping costs though,
unless you're local in the Toronto area.

I'll second the GNT 4601. I use it for punching tapes for my HP system, and
reading old tapes.

Consumer-grade CNC stencil cutters are fine at cutting plastic sheet and should be ok with
film stock.
My ptap2dxf (latest version 1.3) will produce output to cut tapes for 8-level ASCII,
5-level Baudot, 2-level Morse (Wheatstone and
Cable Code), 7-level Whirlwind, Teletype Chadless and some customising options too.
Still some other formats to do such as Colossus etc. Thanks for the notion of making Zuse
tape, will look into it.
Steve.
