I concur with most of what David Empson has described
regarding the interrupt tables in the upper 16k or ram.

I can verify that you CAN use ProDOS if the language card is
enabled and use the emulation and native mode BRK and IRQ vectors
if they are set up previously and the language card is set up
to be at least read from before entering native mode.

The RESET vector is always read from ROM on the IIe/c/gs.
I haven't found use for the COP register (yet).

I am using ProDOS 1.9 to verify the above.  So far I have had
no problems with ProDOS stepping on the vectors for native mode
interrupts.  I would be curious if this will change in the future
for the IIe/c.
