Giving the discussion about building an SE/30 video card in "SE/30 with Grayscale Adaper" it's own thread...
So I was reading a bit in "Inside Macintosh" today and a question hit me. If the address space for each NuBus slot is only 1 MB when operating in 24 bit mode, and the SE/30 is limited to 24 bit addressing, how is it possible to have a video card with more than 1 MB of VRAM (actually considerably less because of ROM/firmware addresses and register space)? Perhaps this was answered in Designing Cards and Drivers... and I've forgotten it. I don't have my copy handy. Still, it's an interesting enough and simple enough question to kick off some discussion. How much VRAM was on the Exceed cards which were made for the SE/30?
