I saw this first on the HP Pascal Workstations in 1983, except that it
was implemented on the last line of the display and you had all of the
line editing commands. This included cursor left/right, char & word
delete, and insert, and had a 255 char limit, regardless of # of
lines.  Control characters were displayed using ascii char labels.
Seems there was more, & I think I remember even hacking some of my own
stuff into the type-ahead buffer routines. I know I used the other two
magic areas on that last line - been too long to remember correctly.

This was really incredible compared to anything else I was using at the
time, especially since it was usually Intel ISIS-II Development
machines (the pre-cursor to CP/M), CP/M boxes, PC's, or HP1000's.
