[GreenKeys] Fwd: Fwd: Looking to purchase a teleprinter

[Jack]

The NY Fire Department resorted to using old-fashioned multi-copy
pressure-sensitive
TTY roll paper in their EXTEL's so the could read the second sheet. The
other problem
their machines had was that almost all of the dot matrix pins were long
gone.

But, FDNY was never bothered by practicality or logic. Their motto is
"One hundred years of tradition, unhampered by progress."

And one problem with any extant Extel machines is that some of them don't
use ribbons, but were intended for use with a special paper stock that had
the ink built into it.  Made originally by 3M.  As was explained to me, the
paper was coated with microscopic white eggs, each egg having black ink
inside.  So when struck by a print wire the eggs broke and produced a black
mark.  So far as I know the paper is no longer available anywhere.
