7b7beb13a3
Eliminates the fiction of setting and getting registers.
...
The Disk II seems lower level than that; it will read the data bus whenever it likes, it is the programmer's responsibility to keep up with that. It also reserves the right not to load the bus regardless of whether it receives a read or write access.

Introduces the Disk II as a unique media target platform.
...
As it makes a little more sense to analyse Apple GCR images to determine target platform than it does to have the potential platforms vote over them.
Also starts on the parser that'll be necessary for making a decision.
