Haha, ok. I guess I’ll order Voultars PCE board and redo the mod. Thank you!

Yeah sorry about the image quality. I have no good lighting and only my cell phone. But the important part that you hopefully can see is the yellow wire on the first image. That is the bottom side of the board, on the other side is the connector that goes of to the A/V out sub board (with composite
and audio out). It is tapped off of that connector, with nothing else on the line.

Thank you. It looks like I was mistaken. Sorry for confusing everyone. The sync line comes off the same connector as the sub board for the A/V out, which leads me to believe the sync is actually composite video?

The yellow wire on the left is going from this connector pad directly to the RGB out sync pin (8 pin DIN connector, looks like it’s wired the “standard” way). The black, white and red wires seem to be ground plus left and right audio.

Should I maybe rewire this to use the sync out from the expansion connector, with something on the way? I see that Voultar sells a board for the PC engine with buffering for sync and 75 ohm. The wiring is quite horrible on this mod, and the AMP is just kind of hovering on top of everything, so I’m thinking about redoing the mod anyway.

Here is the RGB amp used in the mod

Here is what is soldered to the expansion pins. Only R, G, B comes off here. Plus +5V and ground.

It is by an ebayer called 8bitterz.

I have opened the unit up and checked the wiring. It seems the RGB lines go from the expansion port of the console through one of these amps:

And the sync signal I think is straight from the expansion port (Can double check later, at work at the moment). Does the sync line need anything inline with it to be up to spec?

Yeah, I have it set to max
