I love seeing this idea coming back around.  Way back
in college, one of my senior projects was a little OS on
the PDP-11 that was done exactly this way.  The app
language and the command language were a Forth
implementation I had done out of curiosity in my freshman
year.  About a year and half ago, I got it running again,
first in simh, then on a little LSI-11 in those cute little
BA11-VA boxes.  It was wild seeing that running again
after over 30 years, and I found and fixed a concurrency
bug. :)  One of my students did (mostly just started on)
a project his past term that's gotten me to thinking a
little about reimplementing the whole thing on a Pi.
