My guess would be that it uses a reflected playfield with 12 bits
and a quad-with player graphics on each side. By carefully selecting
the shapes of these three objects you could generate the diagonals.
The colours for the three objects could be preloaded, so that there
wouldn't be that many colour changes nessessary during the display
of the cube. You could even change the background colour during the
cube display and have it shine through where nessessary. If the object
pattern and the timing for the colour changes was chosen carefully,
I'm pretty certain that the cube display could be generated this way.
