S-Video/composite board for Atari STs -- great for STFs

Post by vattari » Wed Feb 21, 2018 4:06 am

(I recall a few years back when I first got back into Atari's, I came up with this and was shot down on the Atari Forums. I'll post it for other's reference because, well, it actually worked!)

For countries where SCART is less common, obtaining a better video signal than RF/composite on modern displays required Multisync monitors or genuine Atari monitors. The reason I got this originally is because I picked a very cheap 1040 STF and had no way at the time to use it (my monitor/video handling situations is well and truly sorted now though ;) ).

I came across a RBG to S-Video convertor that I feel got very good results, cheaply. It's the Wei-ya CV-04 RGB CGA to TV composite video converter, available here:

As you can see, you can switch between PAL and NTSC output.

Overall, I was very happy with the S-Video output. The medium resolution photo above of the desktop probably doesn't do it justice, but you can see that most lettering (especially "i's" and "w's") are present and not skewed.

That looks good - when you move the cursor around, do you get de-interlacing artifacts like on the Gonbes upscalers?

I did purchase a GBS8200 around the same time and noticed the mouse pointer “anomaly”.
I have to admit, I don’t have this anymore but I do recall that that wasn’t present.

Stupid question, but what kind of cable to you use from the converter to your LCD. My LCD only has VGA, hdmi, and dvi.
Also, is the cable from the atari to the converter custom.

This adapter is not good for LCD monitors, only for older analog TVs and non-VGA monitors without RGB input. So, I guess that it is little too late for most of people to get it. Actually, we need to add here something what may be good solution too: capture card for PC - they have usually (at least little older ones) S-Video and composite inputs. And you can not only to watch, but can record too your ST actions.
Atari ST cable is surely not in package - that will cost some money or soldering plus.

Just to add that lot of people was able to use diverse monitors at times (1985-2000) without Scart, but with other RGB input connector(s). Like some Commodore ones, intended mostly for Amiga.
There is 2 kind of people: one thinking about moving to Mars after here becomes too bad, the others thinking about how to keep this planet habitable.

It’s just a standard 4 pin S-Video cable. I can’t speak for other regions but in Australia they have been included on TVs as standard from around the mid 90s onwards. They’re less common now (with most LCDs typically have component inputs and composite now at the low end)

The board arrives with just a wiring loom. I added the 13 pin DIN and the audio breakout lead.
I made this one a couple of years back I must admit when I didn’t have any RGB capable monitors (the market is very different in Atari in terms of availability and price) but have since acquired more “authentic” and/or expensive alternatives.
For the Australian market, it’s still a good option though compared to cable only solutions like RF or composite output.
