Personally interesting, on page 16 at the beginning of the driver text it suggests that the XCEED SE/306-48 is a Micron XCEED Color 30. Is that correct, or are there multiple products that map to one or both of those identifiers?
It is interesting to me because I have an XCEED SE/306-48 in my inventory, but I thought that I had confirmed years ago that it is not one of the cards compatible with the internal Grey scale assembly. And I only have the card. I don't have any video connector for it. I think I got it either from a bin at Goodwill or in a large lot of video cards on Ebay a couple of decades ago.
I've seen these docs before and there's a lot of good information there.
The good is that this gives one a basic framework of how to build a video card and fills in a lot of details that might otherwise be tedious or impossible to work out.
The bad is that the internals of the main chip, Mavericks and the two ((?) GALs are not described in detail. Also, it will take a lot of work to make use of the aforementioned details, even though they are present.
Still, knowing what a video card does, and understanding how the Mac sends frame buffer data (two tasks by themselves) and understanding how VRAM works, it should be possible to deduce what Mavericks and the GALs must be doing.
