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.	2017-11-07 21:19:51 -05:00
Thomas Harte	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.	2017-10-21 10:52:35 -04:00
Thomas Harte	75208b0762	Moves the Electron implementation behind a more opaque interface, in line with changes elsewhere.	2017-08-16 15:33:40 -04:00
Thomas Harte	903a17ae11	Corrected typo and removed replication of what's already declared formally.	2017-08-16 14:53:03 -04:00
Thomas Harte	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
Thomas Harte	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
Thomas Harte	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
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	d3bf8fa53b	Upped the documentation.	2017-08-02 20:37:26 -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.	2017-08-01 20:39:10 -04:00
Thomas Harte	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
Thomas Harte	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
Thomas Harte	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
Thomas Harte	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
Thomas Harte	69b99fe127	Transferred ownership of the CRT to the CRTC bus handler, to give it easy access.	2017-07-31 22:04:52 -04:00
Thomas Harte	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
Thomas Harte	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
Thomas Harte	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
Thomas Harte	afd409c883	Ensured that ROM images are loaded and passed to the Amstrad CPC.	2017-07-31 18:44:49 -04:00
Thomas Harte	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
Thomas Harte	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
