ET4000 Graphics card.

[lom@tc.multi.se (Mats Loman)]

I have made some investigations regarding my Spectrum TC graphics card.
I looks to me that you can address all the ET4000 registers as on the PC but 
with the base address 0xFED00000. That means if you want to write a byte to 
port 0x3D4h, you can write a byte to the address 0xFED000000+0x3D4. Can 
someone confirm this??? Is there some good ET4000/VGA dockumentation 
available somewhere?? I think it's possible to implement virtual consoles 
with "REAL" text and graphics modes on a such graphics card. I need some 
dockument describing the registers. So far I have only succeded to make the 
screen totally black :-(.
