Enshrined a default colour burst amplitude. Which now everybody relies on. The 102 figure is derived from the burst apparently being 40 IRE.

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

Switched the 6560 to two bytes per pixel, since one isn't sufficient for precision and because mixing up the implementation might help me to figure out what's amiss.

It seems likely that an AY divides its clock by 8, not 16. I had conflated wave frequency and counter clock.

Made an attempt at read track. Which means process_input_bit can't just swallow syncs any more; it now reports them as tokens of type ::Sync.

The "MFM...Byte"s aren't MFM-specific, they're relevant to both FM and MFM encoding. So renamed them. Also slimmed syntax within MFM.cpp mostly where emigration from the Acorn disk analyser had left a residue of lengthy namespace specification.

Added some even more verbose logging; slightly simplified write loop logic, and decided it's definitely write_byte that's responsible for CRC generator feeding.

Introduced data_mode_ to replace is_reading_data_, representing that there are now three possible modes. When writing, any input from the read head won't affect the CRC generator.

Made steps towards proper CRC generation. Am currently comparing against Oric disk images, as — amongst other things — they include precomputed CRCs.

Started working CRC checking into the 1770. Discovered immediately that my generated CRC does not match that built into the Oric disk images. So mine is pretty-much certainly wrong. An opportunity for learning!

Worked on the all-around framework for decoding sectors back from tracks when closing down a file. Hit the wall that the parser is more observant of CRCs than the WD. No, really. So I guess I have to stop avoiding that whole issue.

2016-12-26 14:24:33 -05:00 |

Deviated from the data sheet, which seems likely to be correct. Hence removed a whole load of the temporary logging.

With lots of logging arising temporarily, fixed bug whereby conversion to a patched track would lead to holding a track with a distinct measure of time, leading to improperly-placed patches.

Shuffled a little to reduce risk of overflow, ensured writing is a loop, still seem to be writing too quickly for some reason.

aceb7e3b6b

Started implementing write sector on the 1770, immediately deciding it would be useful to have a callback for end-of-queued-data-written from disk controller. So had a go at implementing that, naively. More investigation required.
|
2016-12-25 12:31:38 -05:00 |

Added enough stuff that SSDs attached to a 1770 will now reach the entry point for writing.

|
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.

Split the status up into flags, assembled into a register upon demand. Attempted to implement some of the differences between the 1770/1772 and 1773/1793. Albeit with a motor fix still in place.

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

The '72 seems to be a '70 with altered timing. So worth differentiating.

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.

Temporarily disabled spin-down as harmful to the status register if following anything other than a Type 1 command.

Gave the Microdisc a clock signal, added just enough of force interrupt to avoid a spurious belief that a type 3 command has started.

Added getters for the IRQ and DRQ lines plus a delegate to receive changes; adjusted code so that the two lines signal.

Reversed myself. I once again do not think the clock is divided by 256 for envelopes.

|
Switched to more straightforward version of two-step loop, dealing with my mistaken dealing of when _master_divider&15 == 0 upon entry without adding an extra sanity check. Am also temporarily on non-modulo logic for tone generation, for a profiling test.

Sought both to [start to] optimise the AY and correct divider reloads. It turns out that conditionals aren't that troubling. But I can probably eliminate the counters.

Ensured propagation of synchronise messages, added enough to do plain tone. Probably. So: noise and envelopes missing. And it's all far too quiet.

Renamed class, intending to turn a Disk::Drive into literally just that, and have a thing with a PLL that consumes events be a Controller .

Performed an about-face on how this should probably be implemented. Now forsaking the state machine in favour of a macro'd switch-for-cooperative-event-based-messaging implementation. Let's see how this ends up looking.

One painful step at a time, this now starts the disk rotating and gets as far as deciding whether it's about to head off on a read or a write.

Fixed ROM loading by the Electron, turned the WD1770 into a 'disk drive' (it'll do for now), persuaded it to get all the way through a very specifically convenient type 1 command.

This is the start of my slog through type 1 commands. I kind of need to figure out what I'm doing about drives and PLLs now though.

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.

It turns out that the Vic has a 1.6Khz low-pass filter. So added that.

Turned the 6560 into an ordinary template, similar to the rest of the project, albeit right now with a fairly shonky internal implementation. Fixed a Mac-specific interface sizing issue.
