Alright. Supporting the next video mode the RasterOps board switches into nets us this:
VRAM layout in 1 bit per pixel mode on that card is nearly Apple II hi-res levels of weird. Also, it doesn't like my harddisk images created on the (emulated) Mac Plus for reasons I need to investigate (I see where in the code it's rejecting them, I just don't know the details yet), and nobody has a clue how the SWIM works so no floppies pending a major deconstruction of the .Sony driver. Whee
ETA: declaration ROM dumps and chip lists for other Mac II NuBus video cards accepted, PM me ;-)
