For the hotrodders amongst us, I have a schematic for conversion from VGA to RGB with sync on green. It was published in the German magazine Elektor, july 2001. Not much hassle: some capacitors, a transistor and a small IC. They presented it with 3x BNC conn. out, but I can redo the schematic for a normal Mac video connector, if anyone's interested. To me, it seems that the alternative for Mark is a Nubus Colour card. Both mine can do multiscan. Is that common? -mart -- Vintage Macs is sponsored by <http://lowendmac.com/> and...
