Hi I would like to connect the video output of an Amiga A1200 to a VGA monitor. My VGA card gives the following pin information: 1 Red Video 2 Green Video 3 Blue Video 4 Mon ID b2 (not used) 5 Ground 6 Red return (ground) 7 Green return (ground) 8 Blue return (ground) 9 [] Key (no pin) 10 Sync return (ground) 11 Mon ID b0 (not used) 12 [] Mon ID b1 (not used) 13 Horiz. Sync 14 Vert. Sync 15 [] (not used) The Amiga pins are as usual: 1 /XCLK (In) 2 /XCLKEN (In) 3 Analog Red (75 ohm) 4 Analog Green " " 5 Analog Blue " " 6 DI (47 ohm) 7 DB (47 ohm) 8 DG (47 ohm) 9 DR (47 ohm) 10 /CSYNC (47 ohm) 11 /HSYNC " " 12 /VSYNC " " 13 GNDRTN 14 /PIXELSW (Gelock overlay) 15 /C1 (Clock out) 16 Video Earth 17 Video Earth 18 Video Earth 19 Video Earth 20 Video Earth 21 -12V 10mA 22 +12V 100mA 23 +5V 100mA I imagine that the Amiga analog R-G-B signals go straight to the video R-G-B pins, and that the video earth goes to the monitor ground (This is how I connected a Microvitec some time ago – I *presume* VGA is different). I am also not quite certain what to connect for the sync. Is there anything else I should be aware of? For instance, do I have to connect the R-G-B returns on the VGA side? Any help appreciated, Alex
