Drives now have a finite number of heads.
The Amstrad volunteers itself to be single sided. Everything else stays as it was.

Standardises on const [Half]Cycles as the thing called and returned, rather than const [Half]Cycles & as it's explicitly defined to be only one int in size, so using a reference is overly weighty.

Made steps towards proper CRC generation. Am currently comparing against Oric disk images, as — amongst other things — they include precomputed CRCs.

Deintegrated the busy flag and the interrupt request line, as the latter is reset by status reads. Which also means I can start reporting the WD INTRQ line status directly from the Microdisc. That appears to be correct, rather than honouring the Microdisc IRQ select there.

Ensured flag setting is atomic, removed duplication of interrupt request versus busy, found better names for the personality testers, unified delegate protocol.

Now that it can be more explicit, this should admit that it's '93-based, not '73.

It would appear the 1770 and 1773 actually differ in relation to the (non-sensical) ability not to spin-up for a Type 2, and whether a side compare can occur. So the WD1770 class now requires a personality to be specified. Which it singly fails to honour.

Of course, changing the IRQ enable may immediately change the IRQ line. Signal if so.

Interrupt enabling works the other way around I think, and both registers with only one bit defined should probably return '1' in all other places?

Okay, so it looks like both ROM paging flags are the opposite of what I previously had.
