hmm I think maybe in your case you would have to combine the Luma and Chroma (y and c) into one cable with a y splitter and then go into composite with that. But to be honest why would you do that? Always run Y/C (svid) if you can

[CodeHunter]

Success! Thanks to all, I managed to get a S-Video to single male RCA, as well as a RCA "Y" Cable, and combined the two, and it works on my ThinkPad T22!

QUESTION:

Now, I might be pushing it, but is there any way to utilize the RGB connector in the back of 1084S-D1 and connect it to the VGA connector of the PC (or in my case Laptop)?

I am sure the image quality would be much better!

Thanks.

Pretty unlikely, at least, not without some converters the likes of which I can't recall seeing.

*cough* that's hardly S-video *cough*

Seriously, if you're happy go with it.
For the record, you require *two* RCA connections (or any two signals on whatever connector for that matter) for S-video to work. Combining them into a single signal is composite (more or less). Due to frequency overlap a simple combining will usually degrade the resolution to below composite. The adapter you're using may have an integrated low-pass filter to solve this problem.

What I meant with the dangling RCA plug is that *many* (possibly most) mini-DIN outputs use just one of the signals if you're down to composite and don't use the other one - if configured to composite that is, this doesn't magically change because you pull a plug. This lets you use a single S-video connector cable for both S-video and composite (not simultaneously, of course) without requiring an additional adapter/cable. *Some* mini-DIN outputs with >4 contacts use a dedicated contact, so the dangling won't work - depending on the hardware in question. Anyway...

*cough* that's hardly S-video *cough*

My current connection is as follows: I managed to obtain a S-Video (one end) to DUAL female RCA.

Then I obtained a Male RCA, Y-Splitter cable (all three ends are Male), and connected this to my S-Video cable above.

Then I connected one end of the cable (S-Video) to the back of my IBM ThinkPad, and the other TWO Male RCA connectors to Y (Luma) and C (chroma) of my 1084S-D1.

Is this still NOT a true S-Video hookup???

[magnetic]

Yes that is svideo (y/c) hookup. *cough* :rollseyes

[CodeHunter]

Thanks!

I'm not quite following all your steps..

OK, good, so from an S-video plug to dual RCA. So far so good..

What?
Did you just take both RCA plugs (Chroma and Luma) and join them to a single RCA plug?
If so (and I'm not sure), that's no longer s-video..
Or do you have 2 Y splitters and you are just using them as a gender bender???

And this is where I'm totally lost..
What happened to the Y splitter?
You need to go from s-video to separate chroma and luma, and they have to stay separate all the way to the monitor...

I'm sure I just misread something...

Do you think this 15Khz RGB CGA/Component YCbCr to VGA Converter Scale

http://www.ambery.com/rgbcgatovgac.html

Would be able to allow my ThinkPad IBM to be connected to Commodore 1084S-D1 through VGA? (RGB to VGA that is)

What do you think?


Supports legacy computer devices such as Amiga, Atari, etc with compatible RGB output spec.

Thanks!

[CodeHunter]

What about this unit?

I'm pretty sure all those units are for taking a 15khz screen (Amiga, old video game console, etc) and displaying them on a VGA monitor.

You are talking about taking a PC and scaling it DOWN to 15khz for RGB.

I haven't seen that type of hardware...

I have seen some drivers that can do that type of thing for using a DOS MAME PC with an Arcade monitor. And the ArcadeVGA card can do that with full Windows drivers, but that doesn't sound like what you want..

If I understand it, you want to preview whatever is on your PC in whatever resolution to the 1084s.
In that case, a VGA to S-Video adapter is going to be your best bet, I think....
(And many (well???) laptops and PCs already output s-video...)

Yes, exactly! Is there such a thing? Also, by looking at the website again, I think that their propriety cable (9 pin DN to 15 pin VGA) might do the trick?

I also found the 15khz software:

No, you're looking for something like this:

No idea if / or how well it works..
But it matches the description.
You'll still need an s-video to separate chroma/luma cable to connect that to the 1084s.

I see. Thanks for the link. As you mentioned, basically I am trying to connect my IBM ThinkPad, with various emulators (SEGA, SNES, MAME, NEO.GEO, etc.) running on Win XP, and connect it to my 1084S-D1 monitor. The ThinkPad LCD (or when connected to a regular VGA CRT monitor), shows the graphics pixellated (I don't like to turn on those software based filters, to smooth out the image), so that is why I am trying to connect it to a 1084S-D1: The S-Video smooths out the image considerably, but it has flicker (I even set the refresh rate under Windows settings to 75Hz and still see it).

Can anyone verify that the device which desiv posted would work?

I don't understand why you are not just using the S-VIDEO output on your Thinkpad to go to the 1084. Why buy an expensive VGA to [whatever analogue NTSC mode] converter when the Thinkpad already converts its video to S-VIDEO NTSC analogue?

All you need is a $5 S-VIDEO to dual RCA (Chroma/Luma) cable and connect that to the appropriate connectors on the back of the 1084.

Note:

Do NOT merge the two RCA outputs together. You lose the advantage of S-VIDEO this way (unless you really want a more smeared retro composite video look).
