The monitor has no planes.  The display interface board has planes.  The
98782A monitor can be used with several different display board.  You
need to look at the other end of the RGB cable to find the meaningful
model number.

I suspect that you have a 98547 display card with 6 planes.  Very early
X11 servers for this display reported 8 planes and 64 colormap entries.
More recent servers report 6 planes.

No, you will need a different display board.
