I don't see how the memory devices we are given in Q1 can completely fill
the address space spanned by the given 20-bit CPU address bus. If so, how
can I completely decode the CPU addresses for Q2 ?  Do we need to add extra
RAM and ROM banks for Q2 ?

( I calculate 2^16 + 2^17 bytes in the given memory, but I think we need
2^20.....so have I screwed up somewhere?)

Thanks.
