[GreenKeys] TT-712 Teleprinter Question

[Christian Gauger-Cosgrove]

Hello Greenkeyers,

I saw an interesting miniature looking teletype unit on the website of
Jerry Proc (VE3FAB), specifically this:
http://jproc.ca/crypto/tt712.html

Any one here have any information on it? It looks like a somewhat neat
printer. Is it 5-level (is it USTTY? ITA2? Something completely
different?), is it 7-level (1963 ASCII? 1967 ASCII? Is it FIELDATA?
Something completely different?), is it something completely
different?

...That's basically all that I really want to know (other than: "Where
can I get one?") as from some quick Google I was able to deduct that
it runs at 100WPM and looks to be DC signalled (I think).


Cheers,
Christian
