Yes, there is the 24 Bit to TV Converter box which is also available
with RGB-Scart output..

Well together with a Genoa 7900 ET4000 true color card you can also
output Powerpoint on the TV set with 800x600x65 K colors fullsscreen
overscan ! Looks incredible good with powerpoint !
I have used it myself..

24 bit to TV box is an external unit that connects via the 15 pin
output connector of the VGA card. It gets it power from the keyboard
connector, so you need no external power supply..

You can also stick the VGA monitor to it, so if you start no software
driver, your system will be like before.. You see your pictures on the
VGA monitor..
If you start a 2 KByets TSR program it switches the graphics output
to the FBAS(video), Y/C(SVHS/Hi8) and RGB-Scart output..

You can toggle back by a Hot Key to SVGA..

I gonna post a JPEG pic of it in alt.binaries.pictures.misc newsgroup,
so you all can have a look at it...

No, .WAV files are raw 8-bit samples, whereas, .MOD files are a collection of
samples with assigned notes and sequences to make the sound...a .MID is similar
but you'll have to have a preset collection of "voices" for the .MID to use, as
it contains instructions for a MIDI keyboard/sequencer/other device...

There should be an OS/2 .MOD player out sometime soon...Untill then, get a copy 
of the SBOS2.SYS driver and wait...I'm connected to SBCNet which gives me access
to all the latest .MOD players, etc. so when it's out, I'll be glad to Zip it

I presume one of the advantages of RGB for software is that it's
additive: if you have two images that you want to mix, and you have
the pixels as R,G,B color components, mixing becomes trivial (just
average the components).  Many shading algorithms also use this
additive property extensively.  I don't think this is as easy for YUV.

Unless I've been doing things wrong, the inputs don't really have to be

Right.  I frequently use Gaussian activation functions for hidden units in
Cascor nets (and reported this in the original cascor paper).  If you use
something more complex such as Bessel functions, there's the problem of
multiple minima or maxima where you can get hung up.

Since your targets are set to +/- 1 then you must be using some squashing
function (sigmoid, tanh etc) on the output activation level (otherwise
they would take on levels of +/-50 or so). If you want the hidden deltas to be
in the range +/-1 then use the same squashing function. Whatever you do
the deltas indicate the relative error of the hidden units backpropagated from
the output units. Interestingly you can use this error to update the hidden
activation levels (ignoring activations passed down from higher levels) so
that you obtain hidden patterns best suited to obtaining the required
target patterns (for any specific initial set of interconnecting weights).
This could be useful to find out how far you are from final convergence in
a multilayer network.

I can't quite see how you calculate the deltas for hidden nodes, since
you don't have a target to compare your nodes activity with. That is exactly
what the deltas in backpropagation are used for: to backpropagate the error
through the network.
