Composite Video Output for the Atari Falcon 030
If you ever wanted to connect your Falcon to a TV card or
grabbing a video or simply using it with the AV connector of
your TV, you will have noticed that the Falcon doesn't offer a
composite video signal by default. However this signal is
available from the large nonstandard monitor connector the
Falcon offers at his backside.
This article shows you a simple way to build yourself an
adaptor which will allow you to use those yellow standard cinch
cabling to hookup your Falcon to any device that takes composite
video like a beamer, modern TV sets or most TV cards.
Tools and parts
You will need the following:
- a DB25 connector (female, the one with holes in)
of course a DB19 one will do too if you manage to find one :>
- a small metal saw
- a cinch connector (female)
- 10cm of wire
- soldering iron
Falcon video port
If you look at the Falcon's video port you can identify 19 pins.
Take a look from the outside and you will see the following
1 2 3 4 5 6 7 8 9 10
\o o o o o o o o o o/
\ o o o o o o o o o/
11 12 13 14 15 16 17 18 19
The pin layout is organized like follows:
Red Ground 6
Green Ground 7
Blue Ground 8
Composite Sync 12 (That's the one we are looking for.)
The main problem is the monitor connector. DB19 ones as used by
the Falcon are hard to find these days and if you are lucky to
get one, you can skip the following step.
(cxt: You might find those db19 connectors at partsdata.de)
First you will have to make the DB19 compatible plug. So put your
DB25 standard plug into a vice and use the saw to cutoff 6
connectors on the left. Make sure to cut them cleanly or the
remains of the pins will interfere with your Falcon's case and
you won't be able to plug it into the socket.
Now take a file and smoothen the cut. Try and correct until your
DIY DB19 slides easily into the socket. Use the soldering iron
to ensure the shielding stays intact on your customized plug.
Let's turn to the main task now and warm up the soldering iron
to get ready to solder the needed wires to the connector.
Solder a wire to PIN 10 (I did choose a black one to identify it
as GND) and another to PIN 12 which will have the composite
video signal. It is advisable to choose a meaningful color
scheme or you will get lost easily.
Now take the cinch plug apart and solder your composite wire from
PIN 12 to the center piece. Afterwards solder the ground-wire to
the shielding of the cinch plug. Reassemble the cinch plug and
fix the soldering points with some plastic glue.
Now you are finished. To test your cable, simply put your new
adaptor into the Falcon's video port, and connect it to your TV
with a cinch cable.
Now it's time to enjoy RGB demos and video capturing :)
