6845-related. May or may not be important for

reasonable emulation.

0x60001C: Only read; might be a latch of some sort. It is

read each time M0's interrupt service routine syncs
|
||||
with the i860's to have them update the frame buffer.

0x703000: (VC only) Likely analog axis for VR headset

is always read at the same time as the other two

- Assuming a single framebuffer, as I think we are at the moment,
|
||||
how are all the CPUs writes to the framebuffer prioritized,
|
||||
if at all? The zero values written by the 68k side erase
|
||||
the i860-generated FB data (i.e., zero maps to black in the
|
||||
pallette). On the other hand, treating the zero values as
|
||||
transparent doesn't quite look right either. Could just the
|
||||
i860s each have their own framebuffers? After
|
||||
all, since each eye of the binocular sees a slightly different
|
||||
picture, the i860's might just maintain their own. Then maybe
|
||||
the 68k shares with each of the two, since I think it just
|
||||
generates a single picture (not sure about that either).
