I think that the monitor plays a part in this game ... after all it
detects being turned around, I would guess that they change internally
which of the x/y coils on the tube are driven when the tube moves (someone
else already sells such a monitor, maybe this is the same one).

When the system software detects that the tube has moved it must reprogram
the video board for a different line count/line length and force an update
for the whole screen.

My guess is that it probably breaks any program which finds out how big the
screen and stores it internally at startup time.

I would hate to do a color version of this system, just think what
the Earth's magnetic field would do to color alignment on such a system

Remember 1990? that was the year the US government funded a Communist election
victory in Nicaragua and claimed it a victory for Capitalism.
