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.

d45f1a793d Introduces composite/RGB selection for the Amstrad CPC. 2018-06-21 20:00:49 -04:00

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.

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

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.

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.

75208b0762 Moves the Electron implementation behind a more opaque interface, in line with changes elsewhere. 2017-08-16 15:33:40 -04:00

903a17ae11 Corrected typo and removed replication of what's already declared formally. 2017-08-16 14:53:03 -04:00

1d8edf58dd Ensured that a virtual destructor is declared, so that the various automatically-generated real constructors get in on the action. 2017-08-11 12:07:48 -04:00

caf3ac0645 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. 2017-08-05 19:20:38 -04:00

33ed27c3ad 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

d3bf8fa53b Upped the documentation. 2017-08-02 20:37:26 -04:00

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. 2017-08-01 20:39:10 -04:00

f5b278d683 Added enough stuff to put the emulated Amstrad CPC in a state of knowing whether its '0' key is pressed. 2017-08-01 17:31:56 -04:00

3df13cddd4 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. 2017-07-31 22:32:04 -04:00

c2253c1e0f Fixed multiplier: the dot clock I've used to instantiate the CRT is the pixel clock, not the character clock. 2017-07-31 22:17:46 -04:00

f742fd5d4a Made basic attempt to get something on screen: white where the display is enabled, black for the border. 2017-07-31 22:13:20 -04:00

69b99fe127 Transferred ownership of the CRT to the CRTC bus handler, to give it easy access. 2017-07-31 22:04:52 -04:00

e28829bd1b Corrected CRTC timing, gave it someone to talk to and a means with which to talk. 2017-07-31 20:14:46 -04:00

68ceeab610 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. 2017-07-31 19:56:59 -04:00
Thomas Harte
68dca9d047 Made a first attempt at ROM paging, with pretty much the same scheme that'll be needed for 128kb support. 2017-07-31 19:37:28 -04:00

3c90218c3d With a very basic stab at something a bit like the memory map (sans paging), execution begins. 2017-07-31 19:15:43 -04:00

afd409c883 Ensured that ROM images are loaded and passed to the Amstrad CPC. 2017-07-31 18:44:49 -04:00

9c04d851e4 Added the basics necessary to get the CPU ticking over, at a nominal 4Mhz but with the wait states that I currently believe to be accurate. 2017-07-31 07:29:50 -04:00

1d6fe11906 Added an instance of Outputs::CRT::CRT. So progress is now: select CDT, up comes a blank window. 2017-07-31 07:16:51 -04:00
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. 2017-07-30 22:05:29 -04:00
