WG 25K5501 Sync Issue
« on: August 10, 2008, 02:56:54 pm »
I have a WG 25K5501 in a 1987 Quarterback cab.  Its works fine with the quarterback PCB(NOT jamma), but it wont sync with any jamma boards? 
The quarterback PCB uses both Neg Horiz&Vert inputs seperately.  I tried to use each individually and together with the sync on the jamma harness and no luck.

How do you sync to this monitor with a standard res jamma board?
Jamma is negative composite isnt it? 

I have a 4583 Vid Sync Sep IC, not sure how to use it though...

Also, I have a bootleg Ms. Pac board that has a jamma adapter on it that works fine connected to this monitor using the jamma sync connected to just the neg horz sync.

Could this be a low res monitor?  KLOV says that quarterback is a standard res, but it seems only games made before 1990 and non jamma will work in it??

Agreed .... the only ones lower than that are made by Crayola.
