Arkhan: he meant to say what Pentarou and dhau said: this is not going to work without modifying the monitor.

That sucks. There are other 15khz RGB monitors you can buy in north america. Check craigslist to find one locally for pickup, some thing like a Sony PVM or NEC Multisync XM29 they all have RGB. You'll still need to build the cables though.

You could also try purchasing a upscan converter like a XRGB-2 which has support for 50hz. May cost more but you can use a VGA monitor with it which you should already have, preferably a CRT instead of LCDs.

ill see what I can find. The cable probably works fine then aside from not having the right monitor for it... -_-

'TTL RGB' reads to me as CGA, practically the oldest type of colour monitors for PC. I'm surprised you even got an image. It's a totally different type of signal, there's no way you can get a proper image with just a cable (ANY cable) in between. Just forget that!

dhau suggested the monitor might be modified to support analog RGB input (that would be that 'stamp out' piece of plastic on the right of the DIN connector?). Interesting suggestion! But unless monitors are your bread & butter, I doubt that's worth the trouble, IF it's even possible.

But: do you see those small round connectors on the left? Same type as used for audio connectors, like hook up amplifier -> CD player? There are some simple adapters around that plug into a SCART connector (about 5 Euro / piece), and have a few of those cinch plugs on the other side. Often: audio left, audio right, and video (=composite video, color signal). Find one of those adapter plugs, then get a small length of cable (say 1m max.) with those 'audio' connectors, but use a cable that's specifically suited for video applications! Read: somewhat thicker than the thin, cheapo cables you might use for home audio stuff. Then hook up SCART video signal to the "CVBS IN" connector (on the left, right next to the power cable in above picture), and check the image quality (especially 80-columns text, and 512-pixel width screen modes).

Image quality good enough? Done.
Not good enough? Just toss that monitor (eBay, give it away, or dump it in environmentally-responsible manner).

CVBS (composite video) is far from optimal, especially for an MSX2. But maybe the CVBS signal on your SCART connector is good, the monitor's CVBS input works good, and good quality cable gives you an acceptable image. It would be a shame to dump that monitor if that were the case! Just try it, and check the image quality you get.

Doesn't the computer have a CVBS out as well?

(Now lets hope it can handle a PAL CVBS signal... but usually, CVBS sucks ass compared to RGB... VERY fuzzy!)

well remember I am in the US, so it is an NTSC monitor.

I saw on eBay a little adapter... let me find it

*search*

Is this what you are talking about? I could run the yellow plug straight to my monitor's CVBS and cross my fingers?

I definitely wont be busting the monitor open to add a din. Its not worth the trouble lol. >_< speaker is blown in the beast anyhow.
