Sega Naomi to RGB Scart

Post by Beaps »

Hi all

Is there a way to connect a Naomi to an RGB TV. I know you can flick the dip to 15Khz but can you take the RGB and Vsync/Hsync from the VGA port and wire it to scart. Would it need a sync stripper at all?

Any help appriciated

Just tie the H and V Sync together and you should be fine, or if you are using a Jamma style I/O just grab the C-Sync from there.

I think there's a lot of confusion around what this device does. As Naomi doesn't output Composite Video, there's nothing to strip to get RAW sync. :)

Or it's simply a confusion of terms and he is talking about a sync combiner like the ArcadeForge Ultimate SCART Adapter, BBS Kenzei or DIY.

SEGA I/O already combines the syncs to get CSYNC, no need for any additional device. It has RGBS through JAMMA pins, just wire a scart cable with 220ohms on each signal, that's enough.

What about powering the Naomi. Is there any alternative than the Sun power supply?

Lots of info on the web on how to rewire a standard PC PSU to take place of the Sun power supply.

I use a small PC ATX power supply like this one:
