My board has a string of Chinese characters with a "III" in it.  To the 
right of that is "GBS 8220 V3.0".  Below is "CGA/EGA/YUV TO 2VGA" and 
below that "2009/07/15".

I also misspoke on the suggested wiring change mentioned in the booklet. 
By default, HSync (grey wire) connects to composite sync on the board. 
The change they call out puts HSync on, well, HSync.  I'm reasonably sure 
I tried this myself.
