How do I connect my ST to a TV (NTSC) ?

Post by mbricou » Tue, 13 Jan 2004 04:30:53


I am in an NTSC zone. I have a 1040 STF with a SM124 monochrome monitor. My
STF is NOT equipped with an RF modulator, and TVs over here do not have the
Scart (Peritel) connector. What are my options to get access to the color
modes of the ST ?

I have a TV with "ColorStream" component video input. These are 3 RCA
connectors labelled "cY, cB, cR". That's where I usually connect my DVD
player. Can I make a cable and hook up my ST to the TV using those
connectors ?

What are my other options if I want to use the color modes of the ST ? I
came accross some information regarding a ST to S-Video adapter called
"Video Flyer" (I think). Anyone knows where to find one ? Or an external RF
modulator ?

Thanks in advance,
Michael.

Wha...?! A 1040 without a built-in RF?!? Hmm... perhaps the cheapest
option would be to look for a replacement 1040, one with an RF built
in. Or if you're brave (and good with a soldering iron), you could
obtain a non-working ST and transplant the RF modulator.


Might be possible, but without an Atari monitor to hack a cbale from
it will be a challenging hack. And even then I suspect the sync rates
will be all wrong.


To use an external RF modulator you will need to have AV output, which
the ST does not have.

Hmm never saw this, but judging from your description these must be
composite signals with sync and lumination for one color. The ST doesn't
provide these (only R, G and B signals with separate sync, and composite
video in the models that also have a modulator built in (STm/STe)).


Electronic stores probably have converters from R/G/B/Sync to
ColorStream. This would give a much better quality than modulating the
signal to RF. It would be even better if your TV also had composite
video input (just one RCA for the total picture information), because I
_know_ there are simple modulators for that (R/G/B/Sync to composite video).

A final possibility would be to find an old VCR with a scart input.
Might even be cheaper (second hand) :)

It's not that rare. The ST and STf have no modulator. Only STm, STfm and
STe have (guess what the "m" in STm stands for) :)

I have a 1040 without RF too :o)
( it is in german )

Something like this, I suppose:

I was thinking about trying to adapt an RF modulator for Nintendo N64
(they're pretty cheap), but I know the picture quality would be terrible
:(.

Thanks,
Michael

My
the
RF

Hi Michael, I reakon the easiest way out would be to get a Amiga A520
external modulator and make a 13 to 23 pin adaptor. This has a modulator
that produces both rf and composite. The just tap the audio using the 13 to
23 pin adaptor. easy:-). Oh the STF is lacking alot of extra circuitry as
well as the modulator so just dropping in a modulator is not an easy job.

This sounds very interesting. I have an A520 hooked up my a500, and wouldn't
mind giving it a go on my Stacy. How difficult is it to build a 13 to 23 pin
adapter? Any pinouts for such a beast on the net?

Should not be too hard.

stf side.

a520 side.

this is only a theory mind you, if the modulator uses csync you could tie
the v and h sync together via a low value resistor. A little experimentation
would be required. Usual disclaimer apllies of course;-)

Have u taken a look at the RGB To NTSC converter that was posted in an
earlier post?

http://www.yqcomputer.com/

Practical Peripherals had such a beast out in 1988, along with
a slew of other companies. I have never seen any of them for sale
though, neither in this newsgroup nor on ebay.
