I'm in the midst of putting together another of my Frankintoshes - this time wedging a G4 Mini into the body of an Apple //c. One of the finishing touches I'd like to add is video out to an original Apple monitor. The model I have is a 9'' green monochrome like this one:
Using schematics from this site - http://www.geocities.ws/podernixie/htpc/cables-en.html#vgavideo - I built an adapter which seems to work at 640x480@60Hz, with one glaring problem.
As you can see from this photo - http://www.flickr.com/photos/charles_mangin/6926854065 - i'm having issues with the horizontal sync. The picture seems to be clear, but shifted horizontally.
Does anyone here have a suggestion for how to adjust either the monitor or the adapter I've built to connect the Mini's output to monochrome RCA?
