Heh.  Yup, that brings back some memories, all right.  IIRC, there was
also an escape code indicating that the char was a 12-bit char, which
was how you got lower case, I believe.  BTW, now that I think about it,
I think CDC called it "Display Code" rather than what I originally said
("Display Character").

I had the "honor" of writing a driver for a 6400/6600 running NOS's
predecessor (whatever that was called ... SCOPE maybe, or was it COS ?),
to push data out to the first really widely available, commercial graphics
device ... a Tek 4010 terminal.

Lotsa fun ... especially since they had to give me "root" privs, because
I needed to really get down into the guts, and write some code for the
PP's, as well as the CPU proper.

Thanks for the nostalgic sidebar ...!
