For now, at least, c800–cfff is always built-in ROM.
...
Otherwise I probably need to extend my c3 logic to cover the other built-in cards (?)

I think the Apple IIgs Technical Reference explains how these bits interact, and I just had inhibit_all_pages off all on my own.

Attempts to use the other bit of disk drive control, the 5.25"/3.5" select.
...
For the record, the ROM thinks it finds some Smartport devices and then attempts to talk to them. Since none is present, it blocks forever.

Stubs in audio toggle and disk control.
...
It appears that ROM 01 now fails because reading the disk interface register doesn't do as expected. ROM 03 starts hitting what should be the IWM and dies in a surplus of logging.
