[Coco] New "commercial" CoCo3 RGB to VGA Converter?

[Torsten Dittel]

This time with a descriptive subject line, I hope to get some additional 
comments on this one:

http://www.ambery.com/rgbcgatovgac.html

offers a:

15Khz RGB (CGA YUV Component Video YCbCr) to VGA Converter Scaler

for 92US$. From the website above:

"The video displays for the older RGB sources are quite hard to get 
nowadays. If users want the benefit of using LCD flat panel display for 
their legacy RGB source, this converter provides the right solution for 
converting the 15Khz RGB type signals to modern VGA interface signals. 
Glitch-free conversion with high resolution output display of sharp 
frames and fine pixels.

This RGB to VGA converter scaler unit upgrades the older 15Khz RGB video 
signals from sources like arcade game boards to high-resolution VGA with 
progressive scan output for use with TFT monitor, LCD panel, projector 
or HDTV set with VGA input.

-- Fit with both 4:3 And 16:9 Wide Screen VESA/VGA Displays

This RGB to VGA converter is featured the only product in the market 
that supports true 16:9 output with native wide screen resolution at 
1366x768 pixels  for LCD TV or LCD/TFT monitor size larger than 17" or 
1024x768 pixels output for standard 4:3 CRT monitor VESA displays.

The unit converts the signals of a RGB source in a format that can be 
shown on both: a traditional CRT with VGA connector as well as on a 
flatscreen LCD monitor. It digitizes the incoming video signals and up 
converts them with perfect image output quality.

-- Advanced 3D Motion Adaptive De-interlacing

With the motion adaptive de-interlacing technology, this unit easily 
converts the interlaced RGB signals into progressive ones (scanned every 
line). Users shall find pictures much less flickering with more 
graphical presentation. This unit also adopts a variety of technologies 
including automatic 3:2/2:2 file mode detection and non-linear scaling 
to enhance the picture quality for sharp and clear output.

-- 480i/576i Component Video to VGA Converter

This RGB converter also supports 480i or 576i YUV or component video 
YCbCr signals from RGB sources like DVD players, satellite set top 
boxes, media players and all major video game consoles including:

     * Gamecube at 480i/576i mode
     * Xbox and Xbox 360 at 480i/576i mode
     * PlayStation 2 PS2 at 480i/576i mode
     * Nintendo Wii at 480i/576i mode

The interlaced component RGB signals will be converted into progressive 
scan  type VGA or RGBHV signals for high resolution presentation and 
scaled up to 1024x768 pixels or 1366x768 pixels to fit with all sizes of 
  VGA monitors, LCD flat panels or LCD TV displays with VGA inputs.

-- 15Khz RGB CGA to VGA Converter

All the legacy RGB devices with analog outputs at 15Khz horizontal plus 
50/60Hz vertical frequency range can be up converted nicely at high 
resolution on CRT/LCD/TFT monitor, projector or LCD TV via VGA connection.

like the CGA from arcade video games  can also be displayed

The CGA outputs from those arcade game board or the older Amiga computer 
  can now be displayed using a PC VGA monitor or TFT  LCD monitor. All 
new design for low picture noise and detects wider range in game board 
timing.

This converter supports all major RGB outputs from the following gaming 
machine PCBs and all other legacy computer video sources:

     * Amiga
     * Atari computer
     * ICB CM99
     * Subsino
     * CYE
     * IGS
