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.

Made an attempt to shuffle the texture builder to a similar flush/submit pattern as the input builder. Don't care about thread safety yet, as it's obvious I'm going to need to move that back up to the CRT.

Started introducing an extra layer of indirection so as to be able to bind the texture builder to the same flush and submit patern as the array builder.

The remainder of this test isn't necessarily safe to perform if the array length isn't as expected. But in that case the test has already failed, so it's not worth worrying about a partial validation.

Checked some documentation more thoroughly; the 1793 has quite different spin-up (/head load) semantics. So it's another distinct personality. Grrr.

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.
