[GreenKeys] Teletypesetter 6-level Punch Photos

[dmm at lemur.com]

I did a partial disassembly of the punch unit of one of my
Teletypesetter Keyboard Perforators (a 6-level punch) to show
Dave Hunter some images of a different machine.  They're not great
photos, and the punch itself is pretty grubby, but it is interesting
to see the mechanism and a 6-level punch block.  In case you might
be interested, they're online for a while at:

I was pleasantly surprised at the condition of the punch - it's dirty
and has some surface rust, but I was expecting much, much worse.
This is a future project, though, so for now I've just reassembled
(and lubricated) the unit.


In semi-related news, I did get a chance yesterday to see a Linotype
equipped for Teletypesetter.  It's at the Pioneer Village Museum in
Barron, Wisconsin (north of Eau Claire).  See:

and

It's a rather old machine (a Model 5, probably from 1912), retrofitted 
for TTS.  It isn't presently running, but may be in the future.
