Ensured AY registers aren't rewritten just because of a synchronise event. A stall prior to figuring out proper bus logic, clearly.

Altered phase so that it now merely accounts for accumulated error across a frame. Can probably do better.

Fixed inverse characters, added an extra per-frame phase change, based on empirical observation, ensured header guard won't become ambiguous.

Performed enough wiring to put the onus back onto OricTAP to do appropriate things.

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

Made some AY advances; it's now being polled for samples and collecting more information on what it needs to output.

Added a VIA. Now it's time to find out how poor my 6522 emulation is.

Made an almost complete implementation of video. Just one row of the diagnostics cartridge seems to be off, showing thw wrong character set.

Meaningful text! Albeit with the initial 'O' of 'Oric' missing. I guess control codes and NMIs next?

|
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.

Added just enough wiring to add something that will generate the video, one day.

Added enough wiring to get Oric TAPs through to a completely unimplemented Oric emulation.

That's thread safety, subject to the async task queue being made to work...

It's likely this should be set at startup too, based on latest info.

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

Upped MFM clock cycles, switched back to using the typer for the ADFS and adjusted ADFS ROM slots.

Made an attempt to add MFM decoding to the 1770; ensured something is returned when reading the Plus 3 status register again.

Made a first stab at enabling multi-disk machines and thereby obeying (some of) the Plus 3's status register.

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.

Attempted to ensure that ADFS disks get to an appropriately-configured Electron. Not immediately sure why the shift press isn't working; doesn't need to be dealt with immediately.

Added shift-break as a better way to boot suitable disks. Continued attempting to clean the 1770.

Fixed slots for DFS and ADFS to sideways RAM; continued working on the 1770 to get as far as trying to get the body of a sector.

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.
|
2016-09-20 22:14:33 -04:00 |

Corrected and sketched out state machine far enough to get to a complaint about unhandled work.

Added a WD1770 run_for_cycles call. So I really can now move that as far as reporting that it has no disk?
|

|
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.
