Thomas Harte
7890506b16 Gives the SN76489 its proper dividers and personalities. 2018-02-28 22:36:03 -05:00
Thomas Harte
87760297fc Fixes underpumping of SN76489. 
Audio works now. Though I still need properly to confirm who owns dividers in practice. I think probably all division should be within the SN.

 2018-02-25 22:47:47 -05:00
Thomas Harte
204d5cc964 Extends JoystickMachine protocol to cover ColecoVision use case. 
Also thereby implements input on the ColecoVision, in theory at least. No input is being fed though, so...

Thomas Harte
ddf1bf3cbf Reintroduces options selection for the Mac. 
For everything except the Vic-20, anyway. That has a somewhat outdated notion of what an options panel should be, corresponding to the work yet to do on its analyser.
 2018-02-12 21:46:21 -05:00

d493ea4bca Introduces a multimachine to handle multi-target static analyser outputs. 
Non-functional as of yet.
 2018-01-28 22:22:21 -05:00
Thomas Harte
e025674eb2 The MSX analyser is now smart enough not to be definitive when it's uncertain. 
The cartridge type has also migrated to being a property of the cartridge, prefiguring my intention to discard the static analyser union.
 2018-01-25 22:16:46 -05:00
Thomas Harte
f2519f4fd7 Decided to focus on 'confidence' over 'probability'. 
Besides anything else, it individualises the measure. E.g. two targets can each have a confidence of 0.8 without each giving the wrong answer about probability.
 2018-01-25 19:02:16 -05:00
Thomas Harte

The SDL target would now be fooled by a hypothetical multi-target, the Mac not yet.

Thomas Harte

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.

Thomas Harte
57bfec285f Makes it optional whether the Z80 supports the wait line. If the wait line isn't in use, runtime costs are decreased because the optional wait cycles need not be iterated over. 2017-08-26 23:08:57 -04:00

e7ad79c79a 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. 2017-08-26 12:59:59 -04:00

0cbc1753b9 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 will often be that of the superclass and not that of the derived class known to the CPC. 2017-08-20 13:18:46 -04:00
