98751e6ac8 Ensures that all result phases are exactly the intended length by replacing accumulation with assignment. 
Also attempts a different version of control mark behaviour. Experiments.

da082673d7 Drives now have a finite number of heads. 
The Amstrad volunteers itself to be single sided. Everything else stays as it was.

b835cb73e2 Merge pull request #241 from TomHarte/DriveEvents 
Devolves `TimedEventLoop` ownership from disk controllers to drives
 2017-09-15 19:15:44 -04:00

662d031e3c Adds exposition on the meaning of a disk controller being in write mode. 2017-09-15 19:14:36 -04:00
Thomas Harte
bf20c717fb The Drive now no longer produces input when in writing mode — other than announcing the index hole. 2017-09-14 22:32:13 -04:00
Thomas Harte
4d4a0cf1d2 Puts the disk controller back into the loop with knowledge about reading mode, and uses that knowledge to cut off the PLL. 2017-09-14 22:30:40 -04:00

b62f3e726a Adds a start-of-execution-phase get-out for drives that aren't ready. 2017-09-12 20:43:53 -04:00

Thomas Harte
2f13517f38 Adjusts the 1770 not to talk directly to the drive about motor status. 2017-09-11 22:10:56 -04:00

fb9fd26af7 Updates the 1540 for the slightly-more modern world of decoupled drives and disks (!). 2017-09-11 22:08:10 -04:00

d3c385b471 Separates the 8272's drive selection signalling from actual drive ownership. 
Thereby returns working motor control to the CPC.

96bf133924 Withdraws requirement for DiskController users to specify a PLL multiplier or to provide rotation speed. 
In the latter case because it's no longer of any interest to the controller, and in the former because I'd rather it be picked automatically.

6d6cac429d Fixes extra time accumulation during track running. 
Introduces a bunch of further asserts, which aided me in determining the fix, i.e. that Drives being responsible for their own setup_track could double-pump the event loop.

523e1288fa Updates the MFM parser to use SingleTrackDisk rather than the equivalent withdrawn Drive functionality. 2017-09-10 17:34:52 -04:00
Thomas Harte
1a96cce26f Implements SingleTrackDisk, a Disk that contains only a single, specified, track. 2017-09-10 17:34:14 -04:00
Thomas Harte
a4e275e1fc Provides an implementation of Drive's new interface. 
Mostly lifted from DiskController. `set_disk_with_track` has been withdrawn in favour of providing a suitable wrapper `Disk` subclass, as being an unnecessary complexity and intermingling of concerns.

6075064400 Adds the ability to query a TimedEventLoop for its input clock rate. 2017-09-10 17:31:43 -04:00

90d2347c90 Extended to permit subclasses that are interested to get sub-run_for information about event times. 2017-09-10 14:44:38 -04:00
Thomas Harte
90c7056d12 Started devolving timed event loop logic down to the drives, moving them closer to modelling real life. 2017-09-10 14:43:20 -04:00

fed2bc9fc9 Merge pull request #240 from TomHarte/C1540 
Simplifies the published C1540 interface and corrects a transcription bug.

ff510f3b84 Explicitly disallows copying of VIAs, and marks the constructor as noexcept. 2017-09-05 21:21:23 -04:00
Thomas Harte
3b12fca417 Corrects non-recurring-pattern adaptation bug: the 'SerialPortVIA' should keep a reference to its VIA, not a copy of it. 2017-09-05 21:19:56 -04:00
Thomas Harte
8eeb7e73cd Adds a commented-out printf that I might like to use again later. 2017-09-05 21:15:56 -04:00

ff24e1de31 Corrects 6522 bridge per has-a-not-is-a template switch. 2017-09-04 21:56:21 -04:00
Thomas Harte
6547102511 Attempts better to hide C1540 implementation details from the reader. 
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.

d538ff5039 Merge pull request #238 from TomHarte/C1540 
Minor tweaks to re-enable proper file selection in the Vic-20.

a49594c6a3 Tweaks Vic20 Machine parent class order so that when turned into a CRTMachine, still successfully dynamically casts as a ConfigurationTarget. 
More thorough thought is required.

3544c0f014 Switches from testing size() != 0 to empty() != true. 
Partly as size() is O(n) but empty is O(1), but primarily for style.

f26fe3756c Merge pull request #237 from TomHarte/6522CleanUp

a42ca290cb 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.

24b3faa427 Deconstitutes the 6522 into component parts, templated and non-templated. 
Adjusts the Oric, Vic-20 and C-1540 accordingly, albeit with the quickest possible solutions.

a1e200cc65 Further strips back the amount exposed in Z80-related headers. 
Almost all opcode table generation macros and code now resides neatly in the world of .CPP.

e6ac939ae0 Reintroduces missing noexcept specifier. 2017-09-01 20:51:31 -04:00
Thomas Harte
b034d4e6f8 Refactors the Z80 to separate out interface and implementation. 
Following the pattern just established by the 6502, puts all implementation specifics beyond the visibility of a human reading Z80.hpp and in subfolders so as to promote the idea that they shouldn't go out of their way.
