to get the machine to boot up and enter BASIC, you CAN ignore all the
paged I/O. this is what i've found.

the FE40/2/3 pokes are essentially to do with the keyboard
and (for the time being) can be ignored. FE4E/F are to handle the IRQ
interrupts. finally FE30, i think, is to switch sideways rom. just
ignore it. 

a good idea is to write zeroes to the paged I/O before running the emulator.

look at the advanced user guide for more details.
