A quick hard-wiring of the OricTAP code to get the first file in a .tap correct, damn the rest, and I'm getting some on-screen feedback. Hooray!

Switched to using a diagnostic ROM for now, as it'll definitely boot without initially requiring either a 6522 or AY. Have some forms appearing which imply I'm not doing badly, at least up to not knowing where I'm supposed to get character pixels from.

This may be feeding bits in the wrong direction or calculting the wrong parity or doing something else amiss but should now be correct as to bytes.

Not having read the C++ synchronisation primitives before, this async task queue is probably incorrect. But nevertheless, let's have a quick go at employing it — in a hideously thread unsafe fashion — for audio generation. What can possibly go wrong?

Eventually reached an implementation of ADC that continues to satisfy all the formalised unit tests while also satisfying the manual BCDTest, that I need to find a way to formalise. I fixed the unit tests for Swift 3 while here, and attempted to do some unrelated NIB stuff with no real success.

Adjusted per tests on StarDot; it appears the tape interrupts may fire during audio output, as if in tape output mode.
