OK, I've finally gotten ahold of one of these things, arrived earlier this week and I've been playing with it a bit. It does get the scanrate to where my Mitsubishi Diamond Pro 91TXM monitor can display Amiga output, however there is a green tint too it. I believe this was touched on earlier in the thread, and I wanted to get other ppls opinion of whats going on with it. Apparently, the 16 bit input expected from the chip is split up between 3 channels as Red: 5, Green: 6, Blue: 5, Where AGA exports 24 bit signal as Red: 8, Green: 8, Blue: 8. I would think this would cause a drop in green tint, and overpowering of blue and red, but I guess my thinking was backwards here. The gentleman making these things seems eager to get an Amiga compatable version working, and was thinking of somehow dropping the extra green bit before it reaches the chip. (I think, I'm not too good at this level of digital electronics) My solution was to solder together 2 vga connectors with a resistor on the green line to bring it down to the same level as the red and blue, and being too lazy to work out the math, was actually going to solder 3 different variable resistors on the RGB lines and adjust the VGA display until it matched what was on my TV through the composite port, then measure the resistance accross the green pot and E-mail him the value for future units. I've uploaded 2 pictures here, of a test pattern (apparently from sweden, just something I grabbed off google images by typing "color test pattern" :-D ) and will edit this post or just add another one when/if they're approved. 1 is of the NTSC tv displaing the test image, and the other is the monitor displaying the same image. Any corrections in what I think is going on here would be appreciated, as I'm so good at hardware engineering that I currently hold a telemarketing job trying to sell cable telephone to people that don't want it. :-D
