* Spin the disk under the read/write head for WOZ images.
*
* This implementation emulates every clock cycle of the 2 MHz
* sequencer since the last time it was called in order to
* determine the current state. Because this is called on
* every access to the softswitches, the data in the latch
* will be correct on every read.
*
* The emulation of the disk makes a few simplifying assumptions:
*
* * The motor turns on instantly.
* * The head moves tracks instantly.
* * The length (in bits) of each track of the WOZ image
* represents one full rotation of the disk and that each
* bit is evenly spaced.
* * Writing will not change the track length. This means
* that short tracks stay short.
* * The read head picks up the next bit when the sequencer
* clock === 4.
* * Head position X on track T is equivalent to head position
* X on track T′. (This is not the recommendation in the WOZ
* spec.)
* * Unspecified tracks contain a single zero bit. (A very
* short track, indeed!)
* * Two zero bits are sufficient to cause the MC3470 to freak
* out. When freaking out, it returns 0 and 1 with equal
* probability.
* * Any softswitch changes happen before `moveHead`. This is
* important because it means that if the clock is ever
* advanced more than one cycle between calls, the
* softswitch changes will appear to happen at the very
* beginning, not just before the last cycle.

* The emulation of the disk makes a few simplifying assumptions:

* * The motor turns on instantly.
* * The head moves tracks instantly.
* * The length (in bits) of each track of the WOZ image
* represents one full rotation of the disk and that each

* that short tracks stay short.
* * The read head picks up the next bit when the sequencer
* clock === 4.
* * Head position X on track T is equivalent to head position
* X on track T′. (This is not the recommendation in the WOZ
* spec.)
* * Unspecified tracks contain a single zero bit. (A very
* short track, indeed!)
* * Two zero bits are sufficient to cause the MC3470 to freak
* out. When freaking out, it returns 0 and 1 with equal
* probability.
* * Any softswitch changes happen before `moveHead`. This is
