English Amiga Board - View Single Post - PAL RGB consoles on 1084S-D2

I'm trying to connect my PAL Gamecube and SNES to my 1084s-D2 via the analogue D-sub RGB connector.

After A LOT of trial and error I built a cable that has the Nintendo 12 pin male connector at one end and a d-sub male connector at the other end by simply wiring RGB, sync on composite and ground.

The Gamecube works very well.

The SNES has a rolling picture. I tried a sync stripper with a LM 1881 and it didn't work. I may need a sync on LUMA cable for the SNES.

Incidentally both work very well on a GBS 8220 using the cable and outputting to a VGA CRT. But the 1084 has the all important scanlines.

What I'm concerned about is the voltage output from the RGB lines. My A1200 outputs around 0.5V R and B with 1.2V on the G The gamecube around 1.2 V. The monitor specs say 0.7V p-p. I see SCART schematics with capacitors and resistors so I'm thinking this is to reduce the voltage output.
