Gives the two sets of switches responsibility for supplying 'state'.
(And fixes language-card state value.)

Attempts to stub in read from microcontroller, and extends command 0x06.
A complete guess on the latter, as if you didn't know.

Seems to do enough padding out to get me to my second failing ADB command.
That's better than failing at the first.

Completes logic for pixel framing. Well, mostly; this doesn't yet allow for auxiliary-using II modes being off to the left.
The perceived effect though is that a frame appears and then freezes. So a clocking issue may still be afoot.
