i was thinking about that,
i would have used a colour tube and made an analog comparater/window circuit to switch the gundrive around acording to the raster position by taking a tap from the scancoils.

2 ciruits,
1st circuit - vertical.
if the beam is below a specific point then power the green gun only.

2nd circuit - horizontal.
if the beam is below a specific threshhold IE it's near the middle (radar) then red gun only.
otherwise use some other combo to give the scores a different colour.

that's if i got the colours right, i havnt owned a bz for about 15years.

prety simple though if you think about it, just the extra expense of a colour tube.
