I have a computer built in Italy that has, what I believe to be, CGA outputs. I would like to pin these outputs to a VGA monitor. Can someone steer me to a previous discussion or web page, or reply with the pinouts. Existing computer output signals: (DB9 connector) pin 1 Analog red 1Vpp w/ 75 ohm load pin 2 Analog gn 1Vpp w/ 75 ohm load pin 3 Analog blue 1Vpp w/ 75 ohm load pin 4 15KHz neg horiz sync TTL w 220 ohm in series pin 5 50 Hz neg vert sync TTL w 220 ohm in series pin 7 and 8 ground Thanks
Your VGA monitor will never be able to handle the format of the CGA characteristics. You will need a CGA monitor. It has to do with the scan rates, and specifications of the video signals being fed out. Jerry Greenberg http://www.zoom-one.com
