Pretty difficult. The tubes are not standard. The deflection yoke
would be
entirely different for the two. Moving the yokes over with the
electronics
might work for that problem. Converting the electron gun drive circuits

might not be too hard, but a circuit diagram would be an enormous
help. But, taking the electronic guts out of a 14" monitor and putting
them
inside a 9" color TV monitor might not fit, since many of the boards
are the full width of the computer monitor's case. Then, the computer
monitor's deflection circuit would try to draw a 14" picture with the 9"

tube's beam. Since the 'leverage arm' of the beam would be shorter,
that might come out closer to what you want, but I'd expect it would
still
need extensive tweaking. Finally, the shadow mask of the TV monitor
would be much coarser, and it would be like looking at a 1024 x 780
VGA display on a monitor only designed for 600 x 400. You would only
be able to read the largest characters.
