S-Video to 3 RCA jacks Chrominance Luminance Audio (C= 1901 monitor)
De Man
I'd like to connect a console (super tv boy III) to my commodore 1901
monitor. The monitor has a 3 RCA plug input (red, white, yellow =
chrominance, audio, luminance) the console has an s-video (DIN) output
connector. I have a cable that is supplied with the console that outputs to
2 RCA jacks (luminance & audio) and this works but gives me a black & white
image (as expected).
So what I'd really need is an s-video to 3 RCA jack cable. Does such a cable
exist? Or do I need to make one myself? Does anyone have an idea about the
pinout?
thanks,

DB,
If that S output jack is wired to the S "standard", the following
pinout should work for Y and C connections and audio will go on another
line(s). I don't know of any commercial monitor that uses RCA jacks for S
video, so you might end up having to make your own cable. The easiest way
is to buy a standard S cable (if you get a long one and cut it in half, you
can make two cables) and cut one end off, then pigtail some RCA cables onto
it. Use shrink tubing to insulate the bundle of connections. You want it
mechanically strong so it will not pull apart if tugged on.
This is the pinout for an S-video connector. It is shown facing the
rear of the monitor/TV, SVHS VCR, or whatever. The connector is a four
pin mini DIN. Note the "keyway" at the bottom. Note also that the
active pins are labeled IN / OUT. If the device is a source of video
like a VCR or DVD player, the pins are OUTputs. If you're wiring a
cable for a monitor, they are INputs. If somehow you get the connections
wrong, you will not damage anything. It just will not work. The most
common mistake in wiring a DIN is mirroring... reversing the connections
left to right. <looking embarrassed because I've done it myself>
CHROMA (C) IN/OUT -------4 3-------- LUMINANCE (Y) IN/OUT
CHROMA GROUND--------2 1-------- LUMINANCE GROUND
[_]
The luminance is the black and white information with sync. The chroma is
the color information. Separated Y and C produces a better picture on a
monitor screen than composite (single wire) video. To connect the Y/C
output of a C64 or C128 to a Y/C monitor or TV, take the Y output and
connect it via a shielded cable to pin 3 of the mini DIN connector. Take
the C output and connect it to pin 4 of the monitor. Don't depend on the
metal shell as a ground connection between devices... some cables do not
use the shell as a shield. Use the Y and C grounds, pins 1 and 2
respectively for the grounds on your shielded cable(s). Audio can be
included in your hookup from the computer to the monitor or to your stereo
system.
One last thing (don't know how common this is)... I bought some new S video
cables (made in China) that had the "hot" and ground leads reversed. That
put both signal lines on the shields! Except for possible interference
problems, I would never have known about that if I had not cut the cable to
use it as described above. Wouldn't hurt to check yours... especially if it
doesn't work when you get it wired up. Who would ever thing to check that?

I think that you want to use a combined video as input and
separate luma and chroma video as output. This requires
more sophisticated electronics than simple cables.
I don't think that you need to do this anyway.
If your 1901 monitor has any of the capabilities
of my 1084, you can configure your monitor to
accept the combined video of your super tv boy III.
Either there is a speparate combined video jack on your
monitor, or you need to change the settings of some
toggle switches or buttons on your monitor. If you,
like 99% of everybodu else, no longer have the monitor's
user's manual, you may need to use trial and error
methods to get your monitor to work with your console.
I think that your monitor needs no adjustment to accept
the audio signal of your console.

Set your monitor to composite input (instead of split-composite) and you
will get color.

Correction, you want an Svidoeo to two-RCA jack cable, and I have been
looking for same, Radio shack doesn't have it, nor do thay have an
S-Video extension cable that I could hack into shape, so I am going to
have to special order (the female 4-pin mini din jack is the hard thing
to get here).
Here is a site that has extension cables (and a whole bunch of other
electronics goodies!)
(Request a catalog and look for Mac ADB extension cables, they are the
same connector...)

It seems one could make a good business here with making those RCA to DIN
adaptors for S-video. I once made a few and sold them for about $5 per piece,
and still made a little profit, but I don't have time to make more of them. I
think it takes me about 5 minutes to make one, and they look like the left
one in the picture:
http://www.chemie.uni-konstanz.de/~welte/adapter.gif
Of course I could also make a female DIN to male RCA adaptor as well, but I
never needed one. It is only needed if someone wants to abuse a Commodore
monitor as a display for modern game consoles or game PCs, and I don't like
this at all.

I guess I'm the abuser here. :-) Mind you, the super TV boy isn't a 'modern
game console' at all. It's a remake of an atari 2600 with 127 games built
in.
Would fit quite nicely on such a retro monitor, actually!
Anyway, I guess the S-Video connector is somehow abused here. There's sound
& audio on 4 lines, probably meaning the video signal is just a composite
signal (instead of chrominance, luminance seperated). So I'm afraid the 1901
won't work as it only has a Chrominance/Luminance/Audio (three x RCA) & a 9
pin RGB input. (for 80 columns)
The cable supplied with the super tv boy has a scart connector _and_ two
jacks. One carying the audio signal, and the other the composite video
signal I suppose. If I fit the video signal into the luminance of the 1901 I
get a white & black picture with flickering sprites in a lot of games.

Why? I use a 1084S/D2 for my PlayStation. Works mighty good, after I squeezed
a LM 1881[1], two resistors and a capacitor in a female SCART plug, in order
to make a decent composite sync signal from a composite video signal.
Somehow, I fail to see the moral issues here. These kind of monitors are
hard to find these days (Unless they have a tuner, and are also called
'portable television', but most of them aren't stereo then, they're ugly
and they're expensive), and I do have a pile of these monitors. And,
as far as moral issues are concerned, they weren't really Commodore
monitors in the first place.
1084's are plain perfect for video editing as well ;)

Re the 1084S-D2: What is it internally, a Philips monitor? I have a 184S-D1
here, which I repaired with Ray Carlsens help (cap short circuited), and it
looks very similar to the Philips CM8833-II, I think even the mainboard could
be swapped between the two, because all ports, switches and knobs are in the
same places. But they are completely different designs, strange.

Hm, actually I don't think I have moral concerns here, it is more about game
console and Atari users getting into the market of "our" monitors and raising
the prices :-) Recently I also got a small pile of 1081 and 1084 monitors and
I think I will have to get rid of them sooner or later. I'm sure I can steer
who buys them by bundling them with the correct cable. The 1081 is nice and
cute (and has that Amiga label), I will keep one myself and the other one is
promised to someone as well. I will get rid of the 1084S-D1 as well, somehow
I don't like it. Doesn't have that automatic vertical resize for 50/60Hz of
the 1084-P anymore, which is quite useful for playing Amiga NTSC games with
proper aspect ratio.

I use my 1702 with a satelitte receiver to watch TV in my bedroom.

No, 1881 rings a bell, sync processor that also has an output for odd/even
field.

Martijn van Buul
Hmm. I *seem* to recall that it was a Thom(p?)son, but I didn't take a
really good look; I only opened it once to make the hole for the RGB
plug slightly bigger, so that it would accept home-built cables as well.
I recently obtained a 1084 from unknown origin as well; it doesn't look
like any 1084 I've ever seen.

Yup. The D2 refused to accept a composite video signal as sync (other
models do), and I really need RGB in order to play my American PS games.

Hear, hear :-) I now see 1702s going as high as $50 because their reputation
is becoming increasingly well known. Of course, it doesn't help that we're
so proud of how good quality they are. ;-P
It's funny how often people use them as a monitor for a VCR or satellite
receiver. I used to watch TV on one of my 1702s, a friend of mine did also
for years, and another friend of mine in Sasketchewan still does!

I had a phonograph that did that some years ago. It was a bad filter
capacitor in the filter portion of the power supply circuit. A new
capacitor fixed it. I assume this could apply to the audio portion of a
cbm style monitor also. A bridge rectifier that is about to fail can also
cause hum, but would be likely to cause the video to flicker as well.
Hope this is of at least a little help.

It looks like a 1902, but it's actually labeled 1084..

Monitor model numbers confuse me, especially those which I never owned
myself. Is there some reference page with pictures of all Commodore monitors
and the model numbers given? I think Bo's page has some monitors, but not
all.

Well, we COULD start taking snaps of ours and collect them into one place..
:-) Well, I started it off.. I'll kill it later if nobody shows any interest.

Please start donating your reasonably sized pictures! The email address is
jo...@kameli.arabuusimiehet.com. You can use the ones already there as a
guideline, but if you have a sharper camera, you can of course use a better
resolution. The digicamera I have access to is not that good.
Just keep in mind that a 1280x1024 sized shot WILL get shrinked quite a bit.

Ah! At least one interested person.. :-) Still no emails with monitor specs
and nice pictures attached, though.

Mostly because I don't have a nice fancy thing called "digital camera"
and/or "Webcam".

Ahh.. :-/ Do you have an extensive collection?
I have an old 1084, a newer case 1083 and a 1942 that I haven't taken pictures
of yet..
Should I just insert a snippet of the Canonical list's monitor section? What
do you ppl think.

Same here :-( I'm thinking heavily of getting one of those 3 Megapixel toys,
but with prices going lower every week it's even less fun to buy one than to
buy a new PC :-(
Monitors in my collection are currently:
1702 (PAL)
1084-P (PAL)
1802 (PAL) this one is dead, it self-destructed when I connected the video
cable!
another 1084-P (PAL)
two 1081 (PAL)
1084S-D1 (PAL)
I also have a few other 1084S equivalent types that are not by Commodore, but
they're so similar that there must be a connection somewhere. One is the
Philips CM8833-II, it is very similar to the 1084S-D1, but internally it is
very different. Yet another one is branded "Hanseatic", but I don't know the
details about it now.

Yes, I've seen Philips monitors that are either 100% the same as the 1084 and
some with a different front panel.. Guess who made the respective C= versions?

A photo of the 1902 might be good.
I managed to borrow the digital camera, I'll be taking shots of my monitors
and additions to my collection (1570, 1571) soon..
