Hello all. A bit of a shot in the dark but after buiding and then after some delay programming the ROM and FPGA I was excited to get the following screen. At first I thought this was a PAL/NTSC issue, but on the schematics the RBG output comes before the video processor (AD724JR0 IC). The AD724 converts the RBG to composite and S-video and yes the chip is set to PAL. But I am getting the image on RGB and composite. Also, it's not the same sync appearance I've seen with other PAL NTSC incompatibilities. I have tried multiple SCART to VGA, Scart to component, SCART to composite, direct composite, S-video on multiple monitors (Sony CRT with component and composite; Samsung sync master VGA, Apple 2 green composite, Panasonic plasma with component composite s-video; overhead projector via and composite). The picture here is Apple IIgs with VGA converter set to PAL is the most stable although all either simply do not detect or have a similar over sized image without sync.
Anyway, in a big picture short version, is there anyone who has seen a similar output from RBG (overscanned and poor sync) who can give me a starting point for trouble shooting this?
