[Coco] Re: Coco on a SVGA monitor using the Xrgb-2 Plus

[Torsten Dittel]

Hi,
I have a Korean ('86 GIME) and an American ('87 GIME) PAL CoCo3

the Korean version works fine via RGB port with a:

- NEC MultiSync 3D
- Commodore 1084S (DSUB9)

the American version works fine via RGB port only with the NEC 3D. With
the 1084S the picture is jittering (ca. 2-5Hz, 2 or 3 screen lines)
vertically and the monitor produces an ugly "bzzz" each time the picture
moves.

Composite video works fine with *both* CoCos on the 1084S. I have to add
that the PAL CoCo3 is *not* using the NTSC c-video out of the GIME (pin
ist not connected), there's a satellite board generating the signal
directly from R-G-B-HSYNC-VSYNC.

Do you remember which mod has to be done to connect the 1084S to a '87
GIME CoCo3?
