What exactly are we looking for here? *I* can read a schematic diagram. The OGD1 schematic (http://www.traversaltech.com/ogd1_images/OGD1_RevG.pdf) is a bit strung out over multiple pages with lots of reference markers, so I can see how it's a little bit confusing to read. Is that the problem? (But making it fit on one page without the reference hops would be really hard -- this is a big schematic). There may also be some de-referencing problems with the chips (I'm not sure they're labeled very well -- teeny tiny, very abbreviated labels). Are you hoping somebody will create a more abstracted version, with, say, *buses* instead of individual data lines? Sort of a block diagram of the board, with chips labeled more completely, etc.? Because that's probably something I could do, if there's a need for it. Or if you want something else, please tell me, so I can tell if it is something I can do. I'm not sure I could explain *why* the PCB is laid out the way it is, because I don't necessarily understand much of the engineering behind it. Speaking of documentation, we're supposed to have PDFs of all 10 layers of this board, right? But actually, layers 2, 4, 7, and 9 are missing from the image directory. Are they somewhere else? Presently being updated? Lost? ( :-O ). It turns out I fried my original XCF file for the color PCB layout image. So now I only have the composed PNG. <Sigh> :-( I was going to do a new, more abstract one that looks less like a circuitboard, since we have ACTUAL photos of the populated PCB now. So, if I want to do this, I'm going to have to find all the layers again and reconstruct it. Fortunately, that wasn't really all that hard, but I hate repeating work due to my own filesystem mismanagement.
