...RGB is really great and all, but wouldnt adding a component option be more useful? Component inputs are more common than RGB, and IIRC component Y/CR/CB values can be calculated from RGB values, surely this could be done inside the FPGA, then just provide a switch/jumper to either output straight RGB or the calculated component?
The PLD I am using is of FPGA architecture (array based) but it is just a baby one and is already nearly full, so the feature would not be free. No game consoles prior to 2000 featured component output, while almost all will have RGB available. If you like old game consoles and good quality video and a component video monitor you probably already own a component video encoder box. Also, because component video is a relatively recent video format, many monitors which feature this input are not compatible with non-interlaced 15kHz video.

Tim, this is awesome! Just the thing to cheaply replace the use of the pc10 rgb ppu for nes mods!
I've been getting email after email asking me about this and already have 3 that want it for sure so please make plenty as I may end up making a big batch order!
I have lots of stock and will offer bulk discounts. The only thing not finished now is website and documentation.

Tim, is there any kind of lag introduced by this? I'd love to order one of these but I'd like to know if there's any lag.
No lag.

Will this board work in a PlayChoice? Plenty of PC-10s out there with dead or scavenged PPUs.
I think it should if fitted with an NTSC PPU. The video output from my board is not exactly the same electrically (you may need to modify the Playchoice video amplifier or something), but other than that I suppose it will work.

This may be way out there, Tim, but do you foresee in the future an HDMI version of this board?
Nah, too hard. The XRGB probably does a better job that I would anyway.

This looks absolutely perfect except for the expansion audio issue touched on earlier. Are you looking into it viletim? I just bought a Famicom and I'm dying to throw this in there, but I gotta have Castlevania 3 sound right!
The internal amplifier was just an afterthought really. As alamone said, you don't have to use it. You can take the audio from the Nintendo motherboard at the right spot after the mixer/amplifier. It's just easier to write the installation docs if the audio comes from two pins on the CPU vs some point on the board which is different for every revision. I'll look into the expansion audio thing later.
