Expanded interface so that an external machine caller can request a string be typed without any knowledge of whatever it intends to do re: CharacterMappers. Which is immediately useful in paste functionality.

Standardises on const [Half]Cycles as the thing called and returned, rather than const [Half]Cycles & as it's explicitly defined to be only one int in size, so using a reference is overly weighty.

Switched to Cycles as the result from the 6502 perform_bus_operation, helping slightly to clarify what you're intended to return and reducing type jumping within the 6502 implementation.

Switched CRTMachine over to use Cycles as an explicit statement of units, and followed through on the effects of that.

Factored out the table-lookup approach to being a typer, and adjusted so as definitely to limit myself to positive offset table lookups.

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

Pulled the 6502 into a CPU namespace, making it an instance of something that has micro-opcodes and schedules them, and factoring out the formulation of a register pair.

Fixed Oric SCART mode by having it change what it's giving to the CRT based on which shader it knows will be active.

Ensured flag setting is atomic, removed duplication of interrupt request versus busy, found better names for the personality testers, unified delegate protocol.

Any Oric-format disks that are inserted now make it all the way to the Oric, along with a request to emulate the Microdisc. It has received a copy of the ROM. The ball is entirely in its court now.

Extended analysis to spot IRQ and NMI vector changes, for titles that simply adjust those then exit. Ensured Oric emulator can type and load quickly on an Oric 1 just as well as on an Atmos.

The emulated Oric now has access to both versions of the BASIC ROM and picks between them based on the static analyser's recommendation.

Switched the Oric implementation simply to rely upon the Storage-level tape parser. So now there's only one, authoritative one of those.

Made the typer much more able to help out, and thereby tidied and separated the Oric's typer.

Implemented typer for the Oric, and I'm starting to think the code is a bit too repetitious. Refactoring will be forthcoming. Added CLOAD"" as the loading command for all Oric software.

This appears to be it. The secret? Don't worry about the stop bits. They're just processing time. Latch onto the next start.

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

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