I just noticed something.  48KB of linear ROM space would require a minimum of
16 address lines.  As far as I can see, the DOC2000 only has 13 address lines
(ie. 8KB address space).  I'm a bit confused here.

How does the DOC distinguish between accesses to the linear ROM and accesses to
the NAND-Flash ?

Thanks,
Brendan Simon.
