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.

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.

something fairly reliable.

Do you mean a punch as a computer peripheral, or a keyboard operated
For the former, the ones you mentioned are obvious choices;
BRPE is another. Also the DEC paper tape reader/punch (PC01 or some such
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.
This requires a REAL MACHINE SHOP ... none this 3d printer stuff. I
would recommend a building a 35mm film punch and reader, as film stock
is still easy to find compared to paper tape. Zuse used them for his
computers in Germany on the 40's. Quality Mechanical stuff is lost high
