3862fdb44c Simplifies initialisation procedure for all machines.
With the side effect of allowing every machine to try to load only the ROMs that it needs.

0b771ce61a Removes all instances of the copyright symbol. 2018-05-13 15:19:52 -04:00

78eaecb29e Provides the proper framework for encapsulation of analyser target specifics.
... while making them a safe container for objects too. Uses the ZX80/81 as the pilot platform.

6b1eef572b Eliminates diamond inheritance of KeyboardMachine::Machine by typers.
Specifically by pulling the key action stuff into a purely abstract class [/interface]. Takes the opportunity to unpublish a bunch of machine details.

7b420d56e3 Removed state mirroring in the machine-specific Mac UI classes. 2018-02-14 21:46:50 -05:00

21efb32b6f Integrates the static and nascent dynamic analyser namespaces. 2018-01-24 21:48:44 -05:00
Thomas Harte
c83b3cefbc Eliminates the generalised special case selectors and ROM suppliers from the CPC, Vic-20, Electron and ZX80/81. 2017-11-24 17:55:28 -05:00
Thomas Harte
7b25b03cd5 Formally standardises machine options and introduces a --help option for the SDL target. 2017-11-20 21:55:32 -05:00
Thomas Harte
82ad0354c4 Adds configuration options to the Vic-20, Oric and ZX80/81. 2017-11-18 19:48:10 -05:00
Thomas Harte
ddcdd07dd0 Modifies the Vic-20 and C1540 to bring them into the realm of self-ROM fetching.
Hence enables Vic-20 support within kiosk mode as currently drafted.

35da3edf60 Implements install_roms on the Electron, Oric and ZX80/81. 2017-11-06 22:14:15 -05:00

9e0907ee76 Completes clean-up of post-formalisation per-machine keyboard code.
At least for now. Standardising on how column + row is encoded might be helpful.

4a66dd9e82 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
Thomas Harte
3831fbaca2 Ensured the ZX80 and '81 also provide the necessary hook for destruction. 2017-08-11 12:11:01 -04:00
Thomas Harte
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
Thomas Harte
2f2071be8a 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
4abd62e62b 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
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
81a3899381 Adjusted the Z80 formally to communicate in terms of half cycles rather than whole. 2017-07-26 19:42:00 -04:00
Thomas Harte
966b5e6372 Adapted the Z80's perform_machine_cycle to return Cycles. 2017-07-25 22:25:44 -04:00
Thomas Harte
b82bef95f3 Decided to follow through on Cycles and HalfCycles as complete integer-alikes. Which means giving them the interesting range of operators. Also killed the implicit conversion to int as likely to lead to type confusion. 2017-07-24 20:10:05 -04:00
Thomas Harte
2ff157cf7a Switched CRTMachine over to use Cycles as an explicit statement of units, and followed through on the effects of that. 2017-07-22 22:17:29 -04:00
Thomas Harte
3f609e17b3 Factored out the table-lookup approach to being a typer, and adjusted so as definitely to limit myself to positive offset table lookups. 2017-07-21 21:18:51 -04:00
Thomas Harte
44e5a03cf2 Removed just-don't-power-the-tape approach to pausing and playing, in favour of being fully communicative. 2017-07-19 19:21:27 -04:00
Thomas Harte
3e5c209039 Added basic Typer support for the ZX80 and '81. 2017-07-09 22:00:34 -04:00
Thomas Harte
d6b87053bf Introduced an explicit record of whether a video byte is latched. It's definitely incorrect to treat the latching of 0 as equivalent to no latching, as the byte that will eventually become video is not strongly implied. 2017-07-08 20:40:19 -04:00
Thomas Harte
54efcb7e2f Made a game attempt at automatic motor control and ensured setting is initialised correctly from the user defaults. 2017-07-08 19:31:20 -04:00
Thomas Harte
e2575d6de4 Routed tape motor selections through to the C++ side of the world, and ensured that manual tape playback works properly. 2017-07-08 19:21:12 -04:00
Thomas Harte
a3684545b5 Added a block on the tape motor for a short period after each time the ROM routine is intercepted for a substituted byte read. To reduce the collision between fast tape and real tape loading. 2017-07-06 22:33:54 -04:00
Thomas Harte
644ef13acd Connected up the fast-tape GUI option for the ZX80 and '81. 2017-06-22 20:20:31 -04:00
Thomas Harte
e1355d4b62 Restored proper video output. 2017-06-21 21:18:09 -04:00
Thomas Harte
0e0ce379b4 Renamed MachineCycle to PartialMachineCycle given that it mostly no longer intends to describe an entire machine cycle. 2017-06-21 20:38:08 -04:00
Thomas Harte
76a64d13a0 Made a first attempt at ZX81 emulation. 2017-06-13 21:25:55 -04:00
Thomas Harte
8b09b4180b This now at least remembers whether it is meant to be a ZX81 and has storage for a horizontal counter. 2017-06-12 21:33:16 -04:00
Thomas Harte
06fe07932a While tidying up, killed an unused instance variable. 2017-06-11 21:21:26 -04:00
Thomas Harte
6b602c74b7 Made an attempt to support memory maps other than the unexpanded default of 1kb. 2017-06-11 19:29:02 -04:00
Thomas Harte
e40d553045 Bumped the tape parser up into the machine to ensure a maintained state. Temporarily disabled normally-timed tape playback. 2017-06-11 18:31:43 -04:00
Thomas Harte
84d2feb2e6 Cleaned up and implemented fast-tape hack. I've decided it'd be better to test some other software, potentially to give multiple issues to think about, rather than sitting around with just the one. 2017-06-11 16:42:49 -04:00
Thomas Harte
8c66e1d99d Factored out ZX80/81 video and rejigged to ensure it will keep ticking over irrespective of whether the machine is supplying data. 2017-06-06 17:53:23 -04:00
Thomas Harte
ca9e8aecd6 Made a seemingly unsuccessful attempt to add tape input. 2017-06-06 10:13:32 -04:00
Thomas Harte
cc4cb45e9d Implemented keyboard input and ensured that the signal generated is marked as composite, putting the colour-suppression ball into the CRT's court. 2017-06-06 09:25:18 -04:00
Thomas Harte
6f7037b2b1 Made an initial stab at outputting half the correct pixels. 2017-06-06 08:55:07 -04:00
Thomas Harte
2fbc7a2869 Made a very basic attempt at getting something that at least demarcates proper graphics output. 2017-06-05 23:32:49 -04:00
Thomas Harte
4983718df7 Got to outputting something to the CRT. Should be just proper syncs and a paper background. It's not synchronising properly, so something is amiss in my timing. 2017-06-05 10:47:42 -04:00
Thomas Harte
7e3a46c33e [Re]discovered that sync may also be a product of the interrupt cycle. So started looking into that. 2017-06-04 21:54:55 -04:00
Thomas Harte
096551ab3e Made a first attempt to hash out the ZX80's bus. Video output isn't yet going though. Can't seem to find clarity on whether horizontal sync is really programmatic. Let's see. 2017-06-04 18:32:23 -04:00
