The Sun-2 Multibus machines can have 7Mb of RAM accessed through the
P2 connector.  The other 1 Meg is used by the bwtwo video card.
This is one-half of the address space usable by the 68010.  The
other half is mapped onto the P1 bus.  (or something close to that).
I think they call it I/O Space and Memory Space.
I have to 4Mb cards in mine, with one meg going to waste.

X11R4 works just fine on my 2/120 running 4.0.3.  Well, a bit slow...
