Thomas Harte
05bcd73f82 Attempts to pull drive ownership into DiskController. 
For the sake of being more intelligent as to drive clocking, hopefully. And, eventually, to support multiple drive selection.

Temporarily breaks ST video in the endeavour.
 2020-01-29 22:18:41 -05:00
Thomas Harte
0e29c6b0ab On further reflection, I think events should occur after the running period. 
I'm testing this now for sanity in 2/4bpp mode.
 2020-01-28 23:26:37 -05:00
Thomas Harte

7e8405e68a Makes 72Hz horizontal sync independently relocatable.

43bf6aca67 Corrects reported scan status for the Amstrad CPC. 2020-01-25 23:46:18 -05:00
Thomas Harte
03d23aad41 Corrects reported ZX80/81 scan status. 2020-01-25 23:27:09 -05:00
Thomas Harte
294e09f275 All these 'override's can be 'final's. 
At least for the purpose of being communicative. I doubt there's much to gain in terms of compiler output — the DiskImageHolder can avoid some virtual lookups but nothing else leaps out.
 2020-01-23 22:57:51 -05:00
Thomas Harte
ba516387ba In all these instances, final => override. So no need to repeat myself. 2020-01-23 22:35:39 -05:00
Thomas Harte
9136917f00 Enables the Oric for 50/60Hz mode switching, inventing PAL60 for the purpose. 2020-01-23 22:14:02 -05:00
Thomas Harte
6802318784 Removes audio_queue_.flush() calls; I don't think I really need to block. At least, not usually. 2020-01-23 20:13:16 -05:00

Thomas Harte
beefb70f75 Adds vertical sync as something that can be run_until. 2020-01-22 22:20:56 -05:00
Thomas Harte
8404409c0d Causes the Atari 2600 to obey normal flush semantics. 
This stuff is going to become more important with run_until.
 2020-01-22 22:05:51 -05:00
Thomas Harte
a71c5946f0 Ensures proper manipulation of scan_statuses, leading to the correct result out of a CRTMachine. 
Possibly with the exception of the TMS, as I appear to have uncovered an unrelated issue there.
 2020-01-21 22:28:25 -05:00
Thomas Harte
d97a073d1b Adds the necessary routine for all machines to be able to respond to get_scan_status. 
They all just as the CRT, as all are currently based on the CRT. Which doesn't currently know the total clock rate it would need to in order properly to scale the answer to the question. Further thought coming.
 2020-01-20 21:45:10 -05:00
Thomas Harte
3c760e585a Switches to accepting a bit mask of events to run_until. 2020-01-20 16:08:21 -05:00
Thomas Harte
cb61e84868 Starts building out higher-level run_until functionality. 
Specifically: you can now run until the next set of speaker samples has been delivered.
 2020-01-20 12:12:23 -05:00
Thomas Harte
8349005c4b Adds CRTMachine::run_until, which will run until a condition is true. 
I want to get to being able to say "run until the beam is 60% of the way down", "run until a new packet of audio has been delivered", etc.

d30f83871d Corrects Jasmin activity light. 2020-01-16 22:59:43 -05:00
Thomas Harte
efd684dc56 Opts the BD-500 in for modified Shugart RDY. 
Hopefully this is correct. I'm presently mystified as to other options.
 2020-01-16 21:34:57 -05:00
Thomas Harte
1972ca00a4 Fixes quick-NTSC-avoidance fix. 
I suspect this is very temporary, but here it is.
 2020-01-16 00:01:16 -05:00
Thomas Harte
c606931c93 Ensures a safe default-selected drive. 2020-01-15 23:56:44 -05:00
Thomas Harte
93cecf0882 Ensures no possible initial NTSC, removes printfs. 2020-01-15 23:47:45 -05:00
Thomas Harte
aac3d27c10 Adds activity indicators for the BD-500 and Jasmin. 
Also slightly cleans up DiskController a little further.
 2020-01-15 23:39:15 -05:00
Thomas Harte
91fae86e73 Factors out paging, implements a bit more of the BD500. 
That is, enough seemingly fully to work, if I force the drive to report ready.
 2020-01-15 23:15:39 -05:00
Thomas Harte
f5c194386c Ties head load to ready. 
BD-DOS no longer perpetually retries.
 2020-01-14 23:45:36 -05:00
Thomas Harte
62c3720c97 Adds status register and shout-outs on other address access. 2020-01-14 23:24:11 -05:00
Thomas Harte
f258fc2971 Adds enough of a BD500 for the boot sector seemingly to load. 2020-01-14 23:15:27 -05:00
Thomas Harte
6b84ae3095 Makes the Microdisc also a DiskController, and simplifies delegate interface. 2020-01-14 22:53:27 -05:00
Thomas Harte
5dd8c677f1 Factors out from the Jasmin the stuff that I'm going to need to repeat for the BD-500. 2020-01-14 22:23:00 -05:00
Thomas Harte
3ced31043a Makes Jasmin autoboot optional, adds a Jasmin reset key, adds the Jasmin to File -> New... . 
Also finally implements KeyNMI.
 2020-01-05 21:57:33 -05:00
Thomas Harte
7361e7ec34 Fixed: the issue was failing to propagate motor control. 
Also it seems to be incorrect to have the Jasmin paged at initial boot.
 2020-01-05 21:35:20 -05:00
Thomas Harte
533729638c It seems like Jasmin paged in at boot, and button = page back in and reset works? 
At least, that gets me a 'boot failed' error. Which is something.
 2020-01-05 20:34:15 -05:00
Thomas Harte
9f30be1c13 Attempts to implement most of a Jasmin disk interface. 
With one obvious omission: there's no way to start it? The real interface had a dedicated button, but I don't yet know what that button did. Research needed.
 2020-01-05 20:05:55 -05:00
Thomas Harte
c1bae49a92 Standardises on read and write for bus accesses. 
Logic being: name these things for the bus action they model, not the effect they have.
 2020-01-05 13:40:02 -05:00
Thomas Harte
e4349f5e05 Slightly clarifies logic. 2020-01-04 21:32:34 -05:00

7b2777ac08 Sorts cases into order; adds copious audio mirrors. 2020-01-04 21:06:21 -05:00
Thomas Harte
0fbcbfc61b Switches to more idiomatic address listing. 2020-01-04 20:35:47 -05:00
Thomas Harte
3ab4fb8c79 Enables an assumption of partial address decoding at the ACIA and PSG. 2020-01-04 17:27:55 -05:00
Thomas Harte
19ddfae6d6 Adds Joystick key code mode, ensures events aren't posted in interrogation mode. 
This should fix Turrican due to the latter change; I'm not aware of software that uses the former.
 2020-01-04 09:45:59 -05:00

414b0cc234 Reintroduces sync write delay. 2020-01-02 23:36:11 -05:00

Thomas Harte
455e831b87 Corrects bug whereby changing pixel mode mid-line will produce an improper amount of data. 2020-01-02 23:18:21 -05:00
Thomas Harte
42ccf48966 Judging by Pompey Pirates Menu 88, vsync should occur a line earlier, ending during line 0. 2020-01-02 20:16:28 -05:00
Thomas Harte
2f8078db22 Switches to should_log as a global when I'm hacking about. 2020-01-02 20:15:48 -05:00
Thomas Harte
23ed9ad2de Corrects application of negative relative scale. 2020-01-01 13:22:21 -05:00

Thomas Harte
90b899c00e Attempts to implement absolute mouse positioning mode. 
Along with mouse direction.
