RGB to NTSC video converter
(Video game to Television set converter)
ALLOWS YOU TO DRIVE A TELEVISION SET FROM
A COMMERCIAL, COIN-OPERATED VIDEO GAME
One of our most popular products, the RGB to NTSC video converter allows you to view the output from a coin-operated video game on a home television set. It runs in parallel with the game monitor and does not effect the picture seen in the game cabinet. The output from the converter can be used to display the game screen on one (or several) television sets connected by a single RCA connector.
Commercial games use a standard known as 'RGB' (red-green-blue) to drive the video picture. Television sets are on a different standard known as 'NTSC'. Our RGB to NTSC converter can be used to put the video game screen on a TV set mounted above your bar so others can watch when the game is being played. Several major manufacturers are using our board to construct new commercial video games using 50 inch (and larger!) projector TV screens.
You can project your game on ANY Television set!
Our board is also a replacement for the board found in the large screen cabinets produced by Dynamo. Many operators have called to tell us that the original board provided in those cabinets will not 'sync up' to many newer video games. Our board sync locks to any stardard resolution source.
The RGB to NTSC converter comes complete with a wiring harness to install it inside your video game cabinet. The connection to your TV is made through an ordinary round RCA cable available in any length at your local stereo store.

The RGB to NTSC converter sells for $129.
FREQUENTLY ASKED QUESTIONS (FAQ) about the RGB to NTSC converter.
WHAT DOES NTSC MEAN EXACTLY?
NTSC (National Television Standards Code) is ordinary video in the United States. It's what we use when we connect a VCR to the TV; that little round plug labeled 'video input' on your TV set.
- HOW COMPLICATED IS THIS KIT TO INSTALL?
Quite simple. Just connect the Red, Green, Blue, ground, sync and +12 volt wires of your game cabinet to the wiring harness we provide and run a patch cord over to your tv set.
- DOES IT WORK WITH MEDIUM OR HIGH RESOLUTION GAMES?
No! Only standard resolution RGB video sources such as a coin-operated video game.
- DOES IT WORK WITH A COMPUTER?
It will NOT work with VGA, EGA, SVGA, or Macintosh. It WILL work on CGA systems if you build this one-chip sync mixer.
- DOES IT WORK WITH AN SGI WORKSTATION?
No, because they are very high resolution.
- DOES IT OUTPUT 'PAL'?
Yes, it does either PAL (European standard) or NTSC. If you have a PAL video game board, the converter can be changed from NTSC to PAL modes by replacing the 3.57 MHz crystal with a 4.48 MHz and changing one jumper wire on the board. Keep in mind that this changes BOTH the input and output frequencies. You can NOT convert an American made RGB (3.57 MHz) video game board's output into PAL (4.48 MHz).
- HOW IS THE CONVERTER POWERED?
You need to provide +12 volts, although the converter will operate normally at any voltage between 8 and 24 volts DC. Most (if not all) coin operated video games have a suitable power supply built in.
- HOW MANY TV SETS CAN I DRIVE WITH ONE CONVERTER BOARD?
You can chain many televison sets together and they will all show the same picture simultaneously. Depending on the quality and length of the cables used, customers have reported good results with as many as twelve sets before requiring an amplifier.
- WILL THE CONVERTER AFFECT THE PICTURE ON THE RGB GAME MONITOR?
No! The converter does not 'load' the drive circuit. The picture on the original game monitor will not be affected by the installation of the converter.
- DO I HAVE TO HAVE AN RGB GAME MONITOR?
No! The converter does not require you to have an RGB monitor at all! Go directly from any video game board to a TV set.
- WILL IT REPLACE THE CONVERTER IN MY DYNAMO BIG SCREEN CABINET?
It will if you swap around a few wires.
- MY GAME HAS POSITIVE SYNC. WILL YOUR CONVERTER WORK?
Yes! Our converter expects negative composite sync, so if you have an unusual video source which outputs positive sync, here is a simple circuit you can build using one component that will invert the sync signal for most applications.
