Hello,

Since the emulator memory model follows Paul Barton's NoCan 32MB/64MB
interface and it uses the MMU extension registers located at $FF80-$FF8F
along with the MMU registers at $FFA0-$FFAF I'll have to move the emulator
vhd interface from $FF80-$FF85 to somewhere else.  I was thinking about the
area right after the PIA's.  It looks like this area might be free?

$FF24 RMB 28 PIA1 IMAGES

I can actually have 2 vhd interfaces easily fit into either area.  The
reason for 2 vhd interfaces is I felt the need to backup my emulated hard
drive already.  If anyone can shed light on this please respond.  If it
sounds good to almost everyone I can change the msdos version of the
emulator along with the os9 driver and device type for the emulated virtual
hard drives.
