Factored out the table-lookup approach to being a typer, and adjusted so as definitely to limit myself to positive offset table lookups.

Settled definitively on flush as more communicative than synchronise (and slightly more locale neutral); culled some more duplication from the Z80.

Pulled the 6502 into a CPU namespace, making it an instance of something that has micro-opcodes and schedules them, and factoring out the formulation of a register pair.

Introduced the ability simply to piggy-back off the CRT's natural phase for the colour burst, thereby eliminating a couple of redundant independent attempts in the Oric and Electron.

Commuted remaining Electron underscores. It would be nice also to factor out the video, but the time hasn't come yet.

Treading water some more, ensured the DFS and ADFS ROMs get to the Electron. It now even inserts the DFS ROM if it has a DFS disk image. Might need to make it a sideways RAM though? Regardless, the next job surely — surely! — has to be to stop avoiding the 1770?

Tweaked disk side density, added call-outs to a WD1770 if the Electron had one (albeit without run_for_cycles yet as I need to figure out the clock rate), added a shell of the basic functions of the WD1770. No implementation yet.

Finally started on generalising the C++ stuff so as to be able to be able to get a working audio binding on the OS-specific side without further repetition by factoring an appropriate protocol out from the Electron and sketching out the correct speaker class for the Atari. Added a method to ask it what a good output frequency would be.

Believing the previous implementation to be overly complicated through premature optimisation, simplified video. It's slightly slower now. Will need work. Immediately to do: figure out how to deal with blank scan lines.
