[GreenKeys] 28 stock ticker?

[Peter Gottlieb]

Oh man I’d love to have one of those. 

Hook up to a microcomputer tied to the net and it could print out selected stocks!

Looking at http://www.navy-radio.com/manuals/tty/jh/bsps/bsp/570series/573-140-100TC.pdf, I discover a different approach..  It's a 6 level 135 baud device the uses a type box instead of the wheel like on a normal tape printer.  Also it types on 1" tape.  Of course it has fractions as well as some other special charters.
