Unfortunately, no. It provides stereo sound in/out, composite video in/
out, and RGB in/out. The later revisions of the standard allow the RGB
signal pins to carry either YUV or S-Video. IIRC, YUV isn't even a
part of the standard.

There's also pins for the D2B automation bus and a signalling pin for
16:9/4:3 source identification.

So that white connector could also be composite sync input. Perhaps
the power connection is obscured somehow.

OK, my apologies...I thought all those RCA jacks were *outputs*!
After all, it does say RGB *to* component, and SCART is RGB, right?

And it also says:

* BRAND NEW; Scart (male) to Component (female) Adapter.
* For 'RGB' scart video signal to high quality 'Y/U/V' component video
signal.
* Signal output from DVD players, Freeview, Sky or Sky+ set-top boxes
to Component Video.

That sure *sounds* like it accepts an RGB signal on the SCART side
and outputs a Component signal on the RCA side.

I thought that SCART was also an *output* connector for AV equipment,
and that it would supply RGB that this box would convert to component.
(And with all those pins, not supplying a little power seems like an
oversight...)

Does anyone know what this $5 thing actually does?
(I'm pretty sure that the $60 box does what I described.)

In any event, this would be a straightforward way to drive a modern
TV from a IIgs RGB signal, perhaps.

Michael,

Okay, I'm a little confused. What is the difference between RGB component
video and Y/U/V component video? And more important to me, would either one
of the boxes (assuming they do what they advertise) give me a better screen
image than just running the IIgs output into my Monitor/TV with Roger
Johnstone's IIgs to SCART cable? As it stands now I get a usable but not
perfect picture. The only problem seems to be in the transition from one
color to another horizontally. For instance, if you have a line of
horizontal black pixels which turn to white there will be one pixel at the
transition that is gray. This creates a horizontal ghosting effect that can
be reduced by judicious adjusting of the contrast and sharpness, but some
color combinations are worse than others. I had the impression from past
threads that this ghosting effect was caused by the monitor not being able
to sync with the IIgs signal frequency.

My monitor/TV (Samsung SyncMaster 940mw) will accept several types of video
input including both SCART and component video but to further confuse me the
component video input is listed as Pr, Pb, Y.
