We once had a 4025 and managed to get vi to run (although
not without suffering for it.)  The secret seems to be: NEVER
use the  key.

So, we "programmed" the  key (extreme right of keyboard)
to send "+" (which is equivalent to  in command mode)
and used the  key as much as possible in insert-mode.

It's a good idea to hit ctrl/L as often as possible (like
when you start and when the screen changes a lot), since the
cursor is often placed on the wrong line; usually, repainting
the screen from scratch will work right.

It turns out that the 4025 will work a LOT better under Gosling's
Emacs; one of our programmers spent a good deal of time writing
a special driver, which is now part of the standard distribution.
Not perfect, but better than vi (because it has knowledge of the
terminal's bizarre behaviour.)  Fortunately, we only had one 4025
and I haven't seen it in months.
