I have a WX and an ST. Both appear to work fine plugged directly into US mains. Should I be worried about overvoltage?

As for how to get A/V into an HDTV, I use a RGB-to-SCART cable with a SCART-to-HDMI converter like this one: http://amzn.to/1cKm0ZJ. The aspect ratio looks okay at 1024x768, and the latency on the A/V path is acceptable.

1chip MSX might not be the most accurate implementation (yes it's a implementation) of a MSX computer but it certainly is not a emulator.

About sync, I believe the problem is that Japan uses clean composite sync and SCART/Europe use composite video as CSYNC.

A pure CSYNC signal will be a digital pulse. As it is output from the VDP it swings 0-5v.

I believe PAL hardware outputs it's SYNC on TV levels (1vpp) with line impedance of 75 ohms. (same characteristics as CVBS signal line)

Hi Michel,

Like SkyeWelse mentionned I would recommend using a 110v --> 100v converter. I have a HB F1XD (MSX2) and althought it worked on 110v, it was emitting an odd buzzing sound which didn't happen with the step down converter so I guess it's probably a safe investment. For monitor, I typically use a Samsung Monitor with a scart connector but those are difficult to find these days and they are prone to capacitors failure (easy fix tho).

With other US monitors & TV, I'm getting pretty good results using a SCART to Components converter like this one:

The resulting image quality is pretty good and it's much cheaper than a XRGB setup but of course offer less options.

mfeingol, maggoo: Where did you get the RGB-to-SCART cable?

If I recall correctly, this is the one I purchased.

I had one from Bas but his website seems to be down right now: http://www.bas-ditta.info

I remember also buying one on eBay recently (search for MSX SCART).

I was trying to buy a Samsung monitor with a SCART connector on the US eBay but Samsung 510MP sold in the US does not have an actual connector, there is just a plastic cover. Just my 5 cents.

Yeah, I looked at that type of monitor as well, but I've also heard stories of this type of monitor having dead pixels, so I'd like to go for a newer model TV/monitor instead. So for now I've opted to order a RGB-to-SCART cable and also a SCART to HDMI converter. According to others on this forum that should do the trick as well with a modern TV. I'll find out soon enough.

At least, I've received my Sony HB F1-XDJ from Japan (in practically new condition - really a wonderful system), and I also got a 110 to 100 volt converter (The VT-200J step up/down converter), and that works very nice. I tried connecting the MSX2+ using composite video to my HDTV. As expected, the sound is fine, but the image was blurry, so I'm hoping my order for the RGB-to-SCART-to-HDMI cable will do the trick.

Composite video usually looks pretty bad on newer TVs. You may want to try it out with an old tube TV if you have one (or you can find one at Goodwill for about $5) Smile It will look a lot better !
