Tech: G08 Color Controls

First time at resurrecting a Sega G80 (Star Trek) so please
bear with me... I just finished rebuilding the monitor and
see only blue traces.

What are the functions of the "cutoff" pots for red and green
on the neckboard? I futzed with both the "cutoff" and "gain"
pots a bit, but didn't get the other colors. I didn't touch
up the solder joints on these pots yet, but they look good.

Where is pin one on the little input driver board on the back
of the monitor? Plugging it in one way (what I thought was the
correct way) I could read the STAR TREK logo (in blue). Plugging
it in what I presumed to be the wrong way showed a multicolored
indeterminable mess around the center section of the screen.

I'm thinking the next step will be to go into selftest mode, test
6 (screen test) and measure the input levels from the xy control
board.

Any hints or tips would be appreciated. I think I'll stay
after work tonight and see if I can finish it up.

Thanks,

Tim
