Well, I received several replys asking for the pinout for driving an RGB projection tv from the Amiga (unfortunately, these replies were in response to my posting asking for exactly that information :-( ). Well, I just gave a presentation to the Boston Computer Society and had a Sony 1020 (I think) projection tv hooked up and it worked flawlessly. Thanks to Ralph at MIT for the use of his cable! Well, here is the pinout...This device is a "jig" that attaches to the 9-pin end of your standard Amiga and out the other end comes 4 BNC connectors for Red, Blue, Green, and Sync. Now, based on looking directly at the end of your current cable, I assume that the pins are numbered: 1 2 3 4 5 6 7 8 9 And the pinout is: Red - 3 Blue - 2 Green - 1 Sync - 8 By the way, I found that the projection tv didn't really like the combined sync line to be plugged into the horizontal sync input...instead, I had to plug it into the vertical sync input and it worked fine. I don't know whether this is just a fluke having something to do with the Sony, or what. Something else that I did, which was quite handy, was to connect the RGB output to the projection tv and the composite output to my monitor so that I could face the audience, see what I was doing, and have an 8 by 6 foot image displayed behind me!!
