If it makes you feel any better, I grew up next to a place that likely dealt with that scrap. They were family friends (recyclers) and let me bring home stuff to mess with, including a 43 and a box of paper. Found it had a modem built in.

Ended up getting banned from my computer for bad grades, and used the 43 to get on my bbs to keep up my Tradewars game. (Yes it burned paper).

Eventually it got scrapped but at least one had a final run lol.

Now I have a 43 on the shelf awaiting repair some day. (Power supply issue).

We had lots of Model 43 TTYs at Bell Labs in Holmdel.  The print was beautiful, the keyboards had a terrific feel, and could be hefted and moved by a single person.  

And then glass terminals with Emacs came into prominence and the 43s (most often used with Unix ed, a line oriented text editing program) were put in a bin that the porters wheeled away, likely to the mechanical graveyard.  And I didn't even rescue one of them.  I had moved on to Emacs.

I still cry myself to sleep some nights when I think about that, 40+ years later.

That looks pretty good! I assume there is no lower case (as I recall,
these can do ASCII or Baudot). I think the Teletype model 43 looked a bit
better (and included lower case with descenders). Some model 43 output is
at https://bh.hallikainen.org/uploads/HfDrc190.pdf#page=14 .

 I've done a lot of projects using Unifont (
https://en.wikipedia.org/wiki/GNU_Unifont ) that uses either an 8x16 or a
16x16 bitmap for each glyph. In products I designed (before retiring a
few years ago), I included the first 65,535 Unix code points. That covers
upper and lower case ASCII plus a lot of glyphs for Japanese, Chinese,
Korean, Arabic, etc. In thos products, I wrote code that converted UTF-8
to 16 bit characters which then indexed into a 1 MB SPI flash to get the
bitmap. In the DSP TU, I used just the ASCII range (all glyphs 8x16) to
drive the display for the menus.

All fun stuff!

Harold
