b2bfee7f96 The SLOTCXROM switch seems to work opposite 
Which seems weird, but I've verified this in some other places.

2c3d6a4dfa Reimplement idx and idy to use 16-bit addresses 
While I have found some conflicting details on how this should be done,
it seems pretty clear to me that IDX and IDY work with 16-bit addresses,
not 8-bit. The inability to do so was preventing us from probing
peripheral ROM (e.g. at $C705, for the disk controller).

4165c1cefc Make idx, idy clearer 
I'm still not confident this is how it _should_ work, but I have found
conflicting accounts online for the behavior of these two modes. The
current code is what allows the Apple II to bootstrap as it should.

ca5276cb6b It turns out we don't use carry for addr modes. 
This fix actually corrects a rather irritating bug where the Apple ][
logo was displaying one-off--e.g., as "pple ][D".
