Scandoubler gurus needed.
Maybe I am trying to be cheap, and maybe I want something with more features and versatility but here is my idea:
I have no idea if this will work since I don't know much about RGB and VGA signals. That is where you come in: My idea: (I would eventually like to build my own cable to eliminate the first two steps but haven't done the research yet.) 1) Connect RGB to VGA adapter to RGB output of amiga 1200. http://cgi.ebay.com/ws/eBayISAPI.dll...121581624&rd=1 2) Connect VGA to S-Video adapter to convert RGB signal to S-Video. http://cgi.ebay.com/ws/eBayISAPI.dll...495930738&rd=1 3) Plug S-Video Lead into Scan convertor / TV tuner. http://cgi.ebay.com/ws/eBayISAPI.dll...e=STRK:MEWA:IT 4) Plug scan convertor into VGA monitor. Do you guys think this will work? I understand I am dealing with two seperate issues. 1 is all the connections being correct and the other is all the signals being converted as necessary. It just pains me to shell out $144 on a scan doubler for the amiga and have that be its only use. With this I can at least watch TV on my monitor and hook my game consoles up to a monitor. Any ideas? Thanks in advance. |

http://batman.jypoly.fi/~saku/lehti/.../liitannat.gif maa == ground, the s-video connector is displayed from the front (look at the numbers). Don't expect miracles from the output. The s-video signal you'll get with the mod will be good if connected to a real TV / tv-frequency monitor, but the converter usually does a lackluster job of converting it to VGA. Also, after writing that I checked out your links. The VGA -> s-video adapter wouldn't even work for you! It requires support from the graphics card, which isn't going to happen in this case.. So, just solder the above circuit to the video encoder chip and plug the resulting s-video signal to a tv tuner / v-box / tft panel's s-video input and you should be ok. |

If you want to use more than one peripheral, buy yoursel;f an XRGB2 sandoubler. This is not for the amiga, it's for everything! You would be able to connect the Amiga to it with ease. However I don't know if you can use productivity and dblpal modes through an XRGB2.
But for games it will be perfect (it even has a hardware emulated scanlines mode :P). You'll spend like 250 dollars but it will serve you for every bloody thing from Amiga to Gamecube to Arcade PCBs. |

The link: http://www.gamefreax.com/lshop,showd...051916387,.htm Seems like a nice box.. The RGB doubling feature is a definite plus. I saw a similar one on lik-sang a long time ago, but they don't seem to have it any more. I think it was about $150.. A lot cheaper but with equal features.. (well ok, no fake scanline-mode.. boohoo :-) |

Don't go for any of those el-cheapo upscan converters... XRGB2 is where it's at, and those shoddy chinese spinoffs have bad quality (like your VBox, )
