Introduced a memory fuzzer, and ensured the Oric uses it.

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.

Factored out the now-sampling binary-level tape player from the Vic and connected it up to the Oric.

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.
