In this case not from the compiler, as it's desireable to keep `run_for` as a non-virtual call, and therefore everything else comes alone for the ride.

Reformulates the Oric more cleanly into the modern world.
...
Specifically: now that the implementation is contained within the CPP file, there's no need to embed the keyboard, tape player and VIA port handler as private classes. Also the pain of additional syntax is reduced, so the keyboard has been bumped up to a fully data-hiding class. I've also transferred overall ownership of the tape player, AY and keyboard up to the Oric itself, with the VIA merely being wired to them, and added a whole bunch of extra documentation.

Arranges for the ZX80/81 to get a peek at target configuration prior to construction. I'm as yet undecided on whether to make this the norm.
2017-08-27 16:42:16 -04:00

Makes it optional whether the Z80 supports the wait line. If the wait line isn't in use, runtime costs are decreased because the optional wait cycles need not be iterated over.

Breaks apart the CPC's 6845 bus handler to obey phase 1 and phase 2, and now back-dates interrupts when appropriate.
2017-08-26 14:07:51 -04:00
Thomas Harte
6e99169348
Permits the 6845's bus state to be examined by an owner, eliminating the need to buffer it in the bus handler. But more than that it allows the CRTC to decide when it adjusts the various outputs respective to the main phase. So a net effect of the change is that the CPC now sees vsync a cycle earlier, because my current reading of the 6845 datasheet is that it is set at the end of phase 1, not the beginning of the next phase 1.

Quick fixes: the binary tape player now considers talk to the sleep observer only if motor control changes. The Amstrad CPC no longer attempts to use the component argument to identify the caller, since this will often be that of the superclass and not that of the derived class known to the CPC.

Split the static analyser functionality so that it's possible just to ask for the set of media implied by a particular file. Extended ConfigurationTarget so that media alone can be pushed to a machine.

Slowed the typer, having discovered that otherwise it has problems transitioning from a shifted to an unshifted character.

Added a decent portion of documentation. But started feeling like I should address my various ownership decisions. Which would justify a separate pull request.

Performed the normative removal from public view of Vic-20 implementation details. Which were hefty.

Moves the Electron implementation behind a more opaque interface, in line with changes elsewhere.

Cut the amount disclosed by the Atari 2600 for public inspection down to the minimum, relocating implementation into the .cpp.

Hid most of the Oric innards, and corrected a potential multi-thread access error emanating from the Mac side of the world.

Consequential to the 6502 change, severs the Atari 2600's cartridge container from its former attempt at runtime polymorphism, in favour of each cartridge's specific hardware being defined as a 'bus extender'.

Remove the 6502's use of runtime polymorphism in favour of ordinary templating.

Introduces active input handling for the AY and uses it in the CPC to give proper, active keyboard input, rather than push-on-select, which was only ever a temporary hack. Also maps a few more keys for the Amstrad.

Started making provisions for a DMA-compatible implementation. Re: the CPC, it sounds like DMA acknowledge might be permanently wired, causing DMA mode seemingly to work from the 8272's point of view.

Ensured the ZX80 and '81 also provide the necessary hook for destruction.

Ensured that a virtual destructor is declared, so that the various automatically-generated real constructors get in on the action.

Fixed test for termination of a key sequence; the previous error will have seen this reduce all multi-key sequences to just the one, and expand single-key sequences to "probably" two, posting an out-of-bounds code to the machine at completion.

Fixed: should be a full-path #ifdef guard, given that this is one of the classes named relative to its namespace.

Ensured counter-intuitive CRTC writes get through, taking the opportunity to correct my handling of port IO in general: selecting multiple devices for input results in a logical AND (i.e. open collector mode), and both the CRTC and gate array will receive data from 'input's if applicable.

Disks are now communicated to the 8272. Which is able to handle four of them.

Switched disk controllers to be instantiated explicitly in terms of cycles, created an Amstrad-specific subclass of the 8272 to record the direct programmatic availability of all disk motors bundled together, and otherwise adjusted to ensure the thing is clocked and that the motor is enabled and disabled appropriately. The 8272 is also now formally a subclass of the incoming MDM controller.

Strung up an empty shell that eventually should contain the 8272, and added appropriate IO decoding to the Amstrad.

Fixed ROM paging port decoding. It should have been fd00 if completely decoded, not df00, but also shouldn't be completely decoded.

Sought: (i) to instruct the CPC that it should be a 664, not a 464, if given a disk image (at least until I have RAM paging implemented for a 6128); (ii) to support ROM selection within the CPC and allow paging in of AMSDOS.

Fixed AY queuing behaviour as handled by the Amstrad. I think I need to come up with clearer semantics here.
