Made an attempt to eliminate creeping tape processing accuracy misses, which implied factoring out the GCM and LCD functions, which I then felt didn't really amount to signal processing.

Switched to a much-more straightforward PLL. I think I'm just fiddling now rather than moving forwards. Probably time to move on?

Switched to specifying bit length as a quotient for the purposes of a PCMSegment and verified that I had the logic for picking a Commodore time zone backwards: bigger numbers are faster, not slower.
Started sketching out a DiskDrive class.

With a history of three pulses, this can track up a 10% sine variation in a 1010101 stream. So I guess this'll do for now?

Improved factoring and increased window of testing, causing both the fast and slow tests to show framing errors.

Factored out the PCM track since it's going to be a useful construct for almost every file format. Documented it a little better.

Started trying to clean up, including commuting the C1540 source file name to match its class name but mainly by adding documentation.

This is probably a valid test. But I'm not completely sure. Time to figure out what's happening on the 1540 end.

Furthered fleshing out of the 1540. Though it doesn't yet receive a ROM so won't even attempt to do anything meaningful.

Attempted to separate out the concept of a serial port and a serial bus, since the bus may be shared, and to establish half duplex communications from the Vic.

Started endeavouring to sketch out the boilerplate for writing a 6522 test harness. Added a default implementation of synchronise to the 6522 too, since not everybody is going to want one.

Made an attempt also to trigger updates upon audio packets being returned, and significantly to reduce the size and quantity of those. This should get down to 11ms latency if the output wave is 44100; I might need to scale up the buffer size as the sampling rate increases or this is going to get crazy at 192Khz.

Increased buffering range of audio as a quick fix for now. Basically means: increased latency as a short-term fix.

Hacked my 6522 to work. Mistake is in not returning output as input when appropriate — i.e. that I'm ignoring data direction. Also fixed K and L keys.

Actually, I'm dithering over whether the 6522 should be an ordinary class or a curiously-recurring template. But it'll need a file, definitely.

System ROMs are now supplied to the Vic-20 wrapper, though they stop there. I also factored key forwarding out of the ElectronDocument and into the superclass, depending upon the child conforming to CSKeyboardMachine.

Reorganised system ROMs out of the Mac-specific folder, adjusted Mac code to expect to find them organised hierarchically (as how many os.roms am I going to have?) and added readme files to explain what's missing from the Git repository.

Back to asynchronous updates and drawing, to try to improve guarantees on audio latency; experimenting with whether other parts of the approach are fundamentally flawed; added a broad-phase for scheduled updates on the 2600.
