So I've got a Super Punch Out with two Sanyo 20-Z2AW's. Just rebuilt one, which looks great, about to rebuild the second. I'm trying to adjust color, & etc, correctly but I don't believe this game has a crt test pattern, unless I'm wrong. Ive got a Wico pattern generator but I think it puts out + sync and the Sanyo is negative, I think. Any ideas on get a color/ hatch pattern on the screen to adjust it just right or am I just going to have to stick to eyeballin' it?
 
The inversion board only inverts the colors not the sync. The original unmodified Wico pattern generator outputs positive sync only. I own one that I modified to have switch selectable positive or negative sync.

The Nintendo Sanyo monitors use negative sync.
