   > The Lisp Machine character set

   Emacs doesn't support such an encoding/charset, does it?  Maybe it
   should?  Is this character set documented somewhere?  The Lisp Machine
   Manual I have seems to say that \210 is BS or Overstrike, not LAMBDA
   (https://tumbleweed.nu/r/lm-3/uv/chinual.html#The-Character-Set).

That now contains both the Unix stored files, and the native one (also
attached).

I'm slightly confused as how to add a new coding system, do I need to
first add a charset (the converted one would be an :ascii-compatible-p
t, and the native nil?)?  I found the manual slightly sparse on this
front.
