Thomas Harte

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.

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

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.

Corrects quick-hack version of border drawing: the assumption that the colour must be the same over a plotted period. Also corrects my entry for colour 15.

Found documentation that makes more sense, and in practice seems to be more correct: the test after vertical sync is for greater than 32, not less. Also I decided to chance my arm on counter reset also resetting interrupt request. The raster effects of Ghouls 'n' Ghosts is now pretty much correct but one line off. I think probably either something is off in my wait-two logic on the post-vsync timer event, or possibly the vsync bit exposed via the PPI doesn't mean exactly what I think it means.

Minor tidiness: included missing headers, and spaced out the ROM type and key lists for readability.
2017-08-03 12:45:42 -04:00

575b1dba75
Formally declared the ZX80/81 and Amstrad CPC as keyboard machines in their public interface. Which means not having to repeat the meaning of set_key_state and clear_all_keys. So: a minor DRY improvement.
2017-08-03 12:38:22 -04:00

bbb17acf3a
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.
2017-08-03 11:50:50 -04:00

ad3a98387f
Within the Typer
framework: hatched out CharacterMapper
as a distinct thing from the target for keypresses, better to formalise responsibility but also to make it easy cleanly to sever that stuff into its own little part.
2017-08-03 11:42:31 -04:00

These should actually both be in the public header, as the types are used in an exposed method.
2017-08-02 22:18:30 -04:00
Thomas Harte
6d510e4e70
Made it no longer public knowledge that any sort of Typer is involved in being a ZX80/81.
2017-08-02 22:17:22 -04:00
Thomas Harte
8e0736fbe6
Reinstated typing ability, albeit with an ugly inline insertion. But I think I can defer dealing with typers to another pull request. The whole issue of keyboard mapping probably needs reappraisal.
2017-08-02 22:16:09 -04:00
Thomas Harte
681d1e2f8d
Breaking its typer for now, adapted the ZX80/81 to having a Z80, not being one.
2017-08-02 22:12:59 -04:00
Thomas Harte

Realised my colour error: mapping the ROM numbers as though they were the hardware numbers. Having fixed that, spotted that I was deserialising R and B the wrong way around and dividing by too much. Colours now appear to be correct.

c6e340a8a2
Wired up the vsync signal. Pen 15 no longer flashes like crazy. Still can't figure out why the palette is so askew; was looking for perhaps some sort of detection of a green screen rather than a colour one, but there's no obvious input for that.
2017-08-01 21:21:59 -04:00
Thomas Harte
31c7153301
Corrected bit to colour mapping for modes 0 and 1. The total palette is still way off but there's consistency between modes now.
2017-08-01 20:52:42 -04:00
Thomas Harte
7e04d00cc1
Fixed key values, causing the new set of keys to work, decreased quantity of output and ensured that pixels appear in modes 0 and 2.

Corrected typo: the input to an AY is BDIR, not BCDIR.
2017-08-01 17:06:57 -04:00
Thomas Harte
3b292273c7
Fixed: BC2 is always implicitly set. The machine is now periodically checking the AY's register 14 (i.e. the first input port), so probably there's enough here now to implement keyboard input.
2017-08-01 17:05:11 -04:00

It's barely an implementation of the 8255, but ensured that data is bounced into the PortHandler, conveniently assuming the interaction mode used by the CPC.
2017-08-01 16:34:13 -04:00
Thomas Harte
58b98267fc
Formally transferred ownership of PIO accesses to an incoming template, and decided to start being explicit about how to specify the interfaces and provide fallbacks for optional behaviour for the new, clean generation of interfaces. A full-project sweep will inevitably occur but I'll try to tie off this branch first.
2017-08-01 16:15:19 -04:00
Thomas Harte
a27946102a
Took a shot at the interrupt counter. Attempts at keyboard reading now recur so it'll probably do for now. I think that next puts me into the realm of needing to implement the 8255.

Had a quick go at properly outputting Mode 1, adding wiring to communicate palette and mode changes to the CRTC bus handler. Colours are off but it's sufficient for now.

Doubled up to ensure that every byte that should be inspected is represented. This makes it clearer that I'm on the right road. A garbled version of 'Amstrad 64k Microcomputer' can be discerned, in a weird grayscale and with the right-hand column missing and skewed output as a result.
2017-08-01 07:56:44 -04:00

As per my keenness for cleanliness improvements corresponding to my ever-increasing C++ ability: turned the Amstrad into something that a factory produces, allowing me completely to hide a bunch of implementation details.

Created a 6845 class and started pushing data at it and clocking it. It doesn't currently have the concept of a bus but will do, hence the in-header implementation.

Thomas Harte
c0f1313830
Performed sufficient wiring to get to the point where attempting to load a CDT creates an instance of the Amstrad CPC and then fails only because the thing vends a nullptr
CRT.

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.
2017-07-27 22:05:29 -04:00
Thomas Harte
968d2bb8ba
Brought Typer
into the new run_for
orthodoxy, making it easier to clock consistently regardless of unit. Which necessitated adding a negative operator for WrappedInts.
2017-07-27 21:53:45 -04:00
Thomas Harte
9ef232157b
Revoked the operator bool() on WrappedInt as providing an indirect means for implicit but incorrect assignment to unwrapped ints. Got explicit about run_for
intention and simplified HalfClockReceiver slightly by building a lossy and a flushing conversion to Cycles into HalfCycles. Adapted the all-RAM Z80 properly to return HalfCycles.
2017-07-27 21:38:50 -04:00
Thomas Harte
8848ebbd4f
Formalised set_interrupt_line's optional parameter as being a count of HalfCycles; corrected PartialMachineCycle.is_wait and effected the proper timing for counter reset on a ZX81.

Thomas Harte
8361756dc4
Switched definitively to the works-for-now approach of requiring an explicit opt-in where somebody wants to clock a whole-cycle receiver from a half-cycle clock.
2017-07-27 07:40:02 -04:00
Thomas Harte

Switched to Cycles as the result from the 6502 perform_bus_operation

Relocated ClockReceiver.hpp as it's a dependency for parts of the static analyser, and therefore needs to be distinct from the actual emulation parts.

Clean ups along the Electron::Tape line: ensured that the ClockReceiver is opted into only once, and that its run_for
