   I thought that whole area was free game for anything that sorta
wanted to use it. Since it's special memory, the MMgr usually takes
bank E0 for its records of handles and the like. I remember talking
with Todd Whitesel about the VOC's 640x400 mode (shr at e1/2000
interlaced with pseudo-shr at e0/2000, I believe), and the fact that
the MMgr tended to put handles in the e0/2000.9fff zone, making it
impossible to reserve or modify that area.

   I didn't know that the HGR page(s) were shadowed to bank e0; I
guess that comes from not having read all of the hardware refs and
the like.
