From the posted rumors about the new ROMs:

! 2. The ST puts the screen near the end of accessible RAM.  Sloppy 
!    programs that have been writing past the end of the screen will give bus 
!    errors if they do so on the 4 meg ST.

- this sounds very strange: Is any access above the current video RAM now
a no-no? then how can one have multiple screens in RAM, writing to one
while displaying another?  Or does this simply mean that writing beyond
4 Megs gives a Bus Error - then that's nothing new: same for the old STs!

- Moshe Braner

PS: where will us mortals get documentation about the new XBIOS call, etc?
