NightSprinter Posted July 15, 2010 Share Posted July 15, 2010 Hey, sorry to dredge up an old thread but is there an update? As I am consolidating my collection this would be great for my STE. Quote Link to comment Share on other sites More sharing options...

Last thing we heard from KJmanns website was that there was an actual working prototype, so things appear to be moving along. That wasn't too long ago.

I have two JVC sc1224's, But iam realy looking foward to this, lcd screen svideo can not wait. Quote Link to comment Share on other sites More sharing options...
+wood_jl Posted April 11, 2011 Share Posted April 11, 2011 I don't suppose this is in the works anymore, then? This page..... http://atari.8bitchip.info/stvid.php .....makes it look like it's not too hard to get S-video out of the ST. I speak in relative terms. Hard for me, but not for one of you experienced tech fellas. Quote Link to comment Share on other sites More sharing options...

Hard for me, but not for one of you experienced tech fellas. If the ST has a video modulator in it, it's pretty easy. I did it to my 520ST by cutting two traces on the modulator board and adding a cap and a resistor. Quote Link to comment Share on other sites More sharing options...
+DarkLord Posted April 13, 2011 Share Posted April 13, 2011 I so wish Atari had put a Blitter chip and the modulator in the STacy's. Would have made my life so much simpler...especially about going for a replacement screen... As far as that goes, just wish they had stuck an STe in the darn thing - that would have been awesome!

+poobah Posted January 22, 2012 Share Posted January 22, 2012 i dont know how they are going to do it without an FPGA. It's the only way I can get a stable image out of the ST. You have to throw some smarts at the sync signals. Quote Link to comment Share on other sites More sharing options...
Alex Ferm Posted January 22, 2012 Share Posted January 22, 2012 I think I have found a solution for myself using comercial products. Atari SCART cable --> SCART coupler --> SCART to S-Video Converter --> S-Video to VGA Is there any reason that this wouldn't work? I have ordered the parts. I will test and post results after I get all my parts.(may be a couple weeks) Quote Link to comment Share on other sites More sharing options...
DrCoolZic Posted January 22, 2012 Share Posted January 22, 2012 I have made all sort of experiment with many different converter without success. The key point is whether your Atari has a RF modulator or not. If it has an RF modulator then there are several solutions because the composite signal is a composite signal! if not you are in trouble Quote Link to comment Share on other sites More sharing options...

I will test and post results after I get all my parts.(may be a couple weeks) My experience is this type of setup works very badly, at least with the systems I've tried it on (I have not tried it on any ST systems), resulting in a black and white picture at the S-Video part. On the other hand, going straight from SCART to an HDMI converter (obviously with a SCART input) has worked perfectly for me on other systems, and you can usually get them around the $45 US range.

I don't have any hdmi devices. The SCART to svideo also puts out RCA so there are a couple of things I can try. Would an SCART to VGA work and give me color?

Goochman Posted January 23, 2012 Share Posted January 23, 2012 If I have an NTSC Mega 2 ST, can I get an ST SCART cable and then use the SCART->HDMI converter to get ST color with an HDMI TV? Quote Link to comment Share on other sites More sharing options...

Composite (RCA) suffers from the same exact issues as Svideo in my experience. In theory, SCART to VGA should work as well as HDMI. Quote Link to comment Share on other sites More sharing options...

Charlie_ Posted January 23, 2012 Share Posted January 23, 2012 I have made all sort of experiment with many different converter without success. The key point is whether your Atari has a RF modulator or not. If it has an RF modulator then there are several solutions because the composite signal is a composite signal! if not you are in trouble This is very true. If your Atari has an RF box in it you get composite video that works as sync for converters. Like SCART to VGA using a XRGB or similar device, With no RF you can tie the H and V sync lines together for sync but it only works with a few devices I've tried. Most do not work this way.

Bill Loguidice Posted January 23, 2012 Share Posted January 23, 2012 Thanks, Alex, I'll order it and see. It will probably take a while to get here, though, since I'm in the US... Quote Link to comment Share on other sites More sharing options...
+poobah Posted June 1, 2012 Share Posted June 1, 2012 So, I've managed to resolve the 'dancing pixels' issue, and can output a reasonably decent S-Video picture. There does remain one issue: 50 Hz stuff. I've gotten varying results depending on the output device, ranging from fine, to black and white only or a rolling color picture. There's no easy way I can fix this, as it all depends on what your particular tv thinks about a psuedo-PAL picture, so 50 Hz is a crap shoot. So is there any interest in a run of ST S-video adapters that work great at 60Hz, and YMMV at 50Hz? Quote Link to comment Share on other sites More sharing options...
thgill Posted June 1, 2012 Share Posted June 1, 2012 I would be interested in one. I have a UK 520STe I can provide feedback on it from. Plus I have a couple LCD TV's that work fine with PAL signals. Quote Link to comment Share on other sites More sharing options...
+DarkLord Posted June 1, 2012 Share Posted June 1, 2012 Refresh our memories, what ST model(s) work with this? Is it STe only, or does it require a modulator, how big, what power supply is needed, etc, etc,... Thanks! Quote Link to comment Share on other sites More sharing options...

Is it STe only, or does it require a modulator, how big, what power supply is needed, etc, etc,... Thanks! It should work on any ST. (though more testing is definitely needed) A small wall-wart will be required The prototype is an external box with a standard ST video cable to the ST, a power input and an S-Video output. One could easily be mounted inside an ST, which would eliminate the need for a power brick. I actually had the 1st stripboard version sitting inside a 1040 STf where the RF modulator would have been.
