Workaround for a weird bug that suddenly appears to manifest: gzgetc is returning the file name, not bytes from the file. Seems to be related to improper initialisation of the next field within the gzFile header. I can't immediately see where ZLib intends to do that so it's a bit mysterious. But the larger-than-8 readers could probably save time by reading in blocks anyway.

More or less rewrote, to use a filled-per-chunk buffer of upcoming pulses rather than working them out as requests come. Which is more straightforward — all the code for a particular chunk goes in exactly one place — and much easier to extend. So threw in a provisional 0104 implementation.

Addressed my dithering here: the file format containers themselves should do nothing but inspect the data to find out whether it is of the correct format. The machine steps are there for machine-specific validation. So it's probably easier to treat a binary ROM image just as a binary ROM image. Therefore, the Acorn-specific .rom detection is now in an Acorn-specific area.

ROMs definitely have no behaviour other than responding to memory accesses. Cartridges might. So picked the more general term. Sketched out a class at least to parse PRG as though it were a cartridge. Hence the static analyser can guess at whether a PRG is a cartridge or an ordinary program.

Fixed parity: now calculated from the actual byte and works the other way around. The Vic now believes it is loading the actual program. So I guess bytes, headers and the lead-in is working.

Lengths I'd taken seem to have been for dipoles, not single poles. So I just doubled the clock rate. Also I was producing each dipole as high then low, when they should probably be low then high. The Vic now at least recognises that something is happening on the tape.

Formalised clock-rate multiplication within disk drives, discovered that the stepper didn't have ideal behaviour for my timed event loop and hence nailed down the semantics a ilttle more.

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.

Started sketching out the basic form here, albeit that it doesn't yet do _the only thing it advertises itself as useful for_.

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

Actually, I think this is the correct conversion from received speed to clock rate. It'll become obvious if it's not when I get back to working on the 1541 itself.

Put sufficiently much of PCMTrack into place to get to a stored list of segments, having determined a common clock rate between them and therefore a complete track length.
