Seeking Xceed Color30 card

Actually, that project was just to clone the Grayscale adapter card. It did not include the frame buffer main card. The main card was based on a custom chip by Micron--not an FPGA unfortunately. So the chances of cloning it without having to redesign the bulk of the logic is nill. Now, it really shouldn't be that hard to whip something up with an FPGA and either some fastish SRAM or an open core DDR2 controller and one DDR2 memory chip. However, figuring out all the ins and outs of properly interfacing to the Mac OS of the time has had me slowed and stopped for a while. It's probably not all that difficult, but it is tedious and there is a lot of information to sort through. One of the hardest parts is knowing which information I actually need. For every useful tidbit I find, I've gone through 20 chunks of old Mac knowledge which don't apply but were in the way. Jeff Walther
