Dreamcast to Arcade Monitor??
tom61:
The problem with doing the DC2Jamma hack is that not all SCART adapters for the Dreamcast are the same. Some put the Dreamcast's composite sync to that pin, but DC sync is too weak for an arcade monitor. Others put composite video to that pin which needs to be split off into composite sync by a LM1881 circuit.
I gave up on the SCART hack and will be going with a VGA box myself. Once the 31Khz sync line is removed, it should work the same way as a PC to arcade monitor hack.

i've tried doing that but no luck. We track down pin 6 which is the 31khz. With that out of the way we hack in side the monitor.
their are 5 wire original from the back of the monitor, red, green and blue, black and gray wires.

If you go back to http://www.gamesx.com/avpinouts/dricas.htm the red, green and blue wires from the monitor connect to the R, G and B outputs from the dreamcast vga box. The Black wire connects to the ground, and if your arcade monitor doesn't have both v sinc and h sinc inputs you can twist these 2 wires together from the dc and connect them to your grey wire which should be your sync.
Me, I used the same hacked pc monitor lead I use to connect my pc to my arcade monitor. After it was fully grounded it worked perfectly.
